Mentalism Tricks: 9 Routines From Easiest to Strongest

Classic, public-domain mind reading effects with complete methods, ordered so each one teaches a skill the next one needs.

Mentalism tricks create one experience: the feeling that someone has just read your thoughts. The methods behind that feeling are surprisingly ordinary. Simple arithmetic, a few words chosen with care, a torn scrap of paper, a partner who knows a code. What turns them into something people talk about for years is the presentation.

This guide teaches nine mentalism tricks for beginners and improvers, ordered from the easiest to the strongest. Every one is a classic from the public domain, the kind of material found in the old books by Theodore Annemann and Tony Corinda and in school maths puzzles, so you can learn and perform them freely. Each routine comes with the effect, what you need, the full method step by step, and notes on how to present it.

How These Mentalism Tricks Are Ordered

The list climbs a ladder of skills. The early routines rely on a mathematical or psychological principle that works on its own, so you can focus on your words and timing. The middle routines add a prop you control (paper, a book, envelopes). The final routines depend on your hands and your attention, which is why they come last.

If you want tricks with a deck in your hands, the mind reading card tricks page covers the key card, the 21-card trick and a full-deck stack. If you like the arithmetic routines here, there are more on the number and math tricks page, including the famous three-questions prediction.

Mentalism Tricks With No Props

These four routines are where every beginner should start. They cost nothing, you can do them over dinner or on a video call, and they teach the most important habit in mentalism: you never look like you are doing a trick. You look like you are paying attention to a person.

1. The Gray Elephant From Denmark

This is the most famous number force on the internet, and it still works in person because of the way you deliver it. Keep the pace brisk and conversational so the arithmetic feels like a warm-up, not the point.

Routine

The Gray Elephant From Denmark

Level
Beginner
Setup
None
Running time
2 minutes

The effect

A friend thinks of a number, a country, an animal and a color without saying anything aloud. You announce that they are thinking of a gray elephant in Denmark.

You need

  • Nothing
  • Optional: a folded prediction in your pocket
  1. The number

    Ask them to think of any number from 1 to 10 and multiply it by 9. If the answer has two digits, they add them together. Whatever number they started with, the result is now 9.

  2. Subtract and convert

    Ask them to subtract 5 (everyone now has 4) and turn the number into a letter: 1 is A, 2 is B, 3 is C, 4 is D.

  3. The country

    Ask for a country that starts with that letter. Almost everyone says Denmark, because the other D countries (Djibouti, Dominica, the Dominican Republic) rarely come to mind under time pressure.

  4. The animal and the color

    Ask them to take the second letter of the country, E, and think of an animal that starts with it, then the color of that animal. Elephant, and gray, are by far the most common answers.

  5. The reveal

    Pause, look at them, and say slowly: "That's strange. There are no gray elephants in Denmark." The laugh that follows is the applause.

Presentation notes

If someone says eagle or emu, smile and say you were picking up something with wings, then move on to another trick. Never repeat this one for the same group: the second time, people start to check the arithmetic and the force becomes obvious.

2. Shapes, Numbers and the Psychological Force

A psychological force uses the fact that, when people are asked to choose quickly within narrow limits, their choices cluster. Mentalists have relied on a handful of these for generations. None of them works every time, so the method below builds in outs: alternative endings that make a miss look like a hit.

Routine

Two Thoughts, One Prediction

Level
Beginner
Setup
1 minute
Running time
3 minutes

The effect

You write something down and hide it. A friend imagines one simple shape inside another, then a two-digit number. You turn the pad around: a circle inside a triangle, and the number 37.

You need

  • A small notepad
  • A pen
  1. Write the prediction

    Before you start, draw a circle inside a triangle on the pad and write 37 under it. Keep the pad facing you.

  2. The shape

    Say: "Picture a simple geometric shape. Now picture a second, different simple shape around it, like a frame." Draw a vague shape in the air with one hand as you speak, a gesture that happens to have three corners. Ask them to keep the picture clear but not to say it.

  3. The number

    Say: "Now a number between 1 and 50. Both digits odd, and different from each other. So 11 wouldn't work, for example." The examples you give remove choices: the most common answer is 37, followed by 35.

  4. Check before you reveal

    Ask them to name the shapes first. If they say a circle inside a triangle, show the drawing. If they say a triangle inside a circle, say you were picking up both shapes and show the drawing anyway: it still looks like a hit.

  5. The number reveal

    Ask for the number. If it is 37, turn the pad around. If it is 35, say "I was one away, three and five, I had the three" and laugh it off. Any other answer: hide the number with your thumb and reveal only the shapes.

Presentation notes

Psychological forces are the honest heart of mentalism: you are genuinely using how people think. Present this as an experiment in how predictable we are, not as telepathy. That framing also protects you when it misses.

Diagram of Two Thoughts, One Prediction. A notepad shows a circle drawn inside a triangle with the number 37 under it, written before the trick starts and kept facing you. The outs for the shapes: if they say a circle inside a triangle, show the drawing; if they say a triangle inside a circle, say you were picking up both shapes and show the drawing anyway. The outs for the number: 37, turn the pad around; 35, say you were one away, three and five, you had the three, and laugh it off; any other number, hide the number with your thumb and reveal only the shapes.
Every answer has an out: the drawing is never wasted.

3. The Clock Trick

This is a classic counting principle from the old puzzle books. It is completely self-working, which means it cannot fail if you follow the count, and it looks like you are tuning into someone's thoughts as you touch the numbers.

Routine

The Clock Trick

Level
Beginner
Setup
1 minute
Running time
3 minutes

The effect

A spectator thinks of an hour on the clock. You tap around the clock while they count silently, and when they say stop, your pen is resting on the exact hour they thought of.

You need

  • A clock face drawn on paper (or a real analog clock)
  • A pen to point with
  1. The choice

    Ask the spectator to think of any hour from 1 to 12 and keep it to themselves.

  2. The counting rule

    Explain: "Each time I tap a number, count one silently in your head. Start counting from the number after your hour. So if you thought of 5, my first tap is 6, the next is 7, and so on. When you reach 20, say stop."

  3. The first seven taps

    Tap any seven numbers at random. Count your taps silently. These taps do not matter, so make them look casual.

  4. The eighth tap

    Your eighth tap must land on 12. From there, move counterclockwise one number per tap: 11, 10, 9, 8 and so on.

  5. The stop

    When they say stop, leave your pen where it is and ask them to name their hour. Your pen is already on it.

Presentation notes

The arithmetic behind it: a spectator who chose hour h says stop on tap number 20 minus h, and your tap number k (from the eighth on) sits on hour 20 minus k. The two always meet. Slow down slightly from the eighth tap onwards, as if you are feeling for the answer.

Diagram of the Clock Trick. Your first seven taps go anywhere on the clock. Tap 8 lands on 12, then each tap moves one hour counterclockwise: tap 9 on 11, tap 10 on 10, tap 11 on 9, and so on. Worked example for a spectator who thinks of 5: they count 6 to 12 on your first seven taps, 13 on tap 8, and reach 20 on tap 15, when your pen is on 5.
Their count of 20 and your pen always meet on their hour.

4. Black Magic: Two-Person Telepathy

Two-person codes are the oldest form of stage mind reading, and the parlor game known as Black Magic is the simplest version. It is perfect for a party, because the group tries to crack the method and keeps asking for one more round. If you want to go further with partner acts, the guide on how to read minds as a performer covers more ambitious systems.

Routine

Black Magic

Level
Beginner
Setup
5 minutes with your partner
Running time
5 minutes

The effect

Your partner leaves the room. The group chooses any object. Your partner comes back, you point at objects one at a time asking "Is it this?", and your partner says no, no, no, then yes, on exactly the right object.

You need

  • A partner who knows the code
  • A room with objects of different colors
  1. Agree the code

    The rule is simple: the chosen object is the first one you point to immediately after pointing to something black.

  2. The choice

    With your partner out of the room, let the group choose any object. Make a show of ensuring nobody can signal through the door.

  3. The questions

    Call your partner back. Point at several objects that are not black, asking "Is it this?" each time. Your partner says no.

  4. The signal

    Point at something black (a phone, a shoe, a TV screen). Your partner says no. Next, point at the chosen object. Your partner says yes.

  5. Repeat with variety

    Do it two or three times, varying the number of objects before the signal so no pattern of counting appears.

Presentation notes

When people guess "it's the black object", switch to a backup code you agreed in advance, for example the object comes after one with legs. Changing codes is what makes Black Magic last a whole evening.

Mind Reading With Paper and Pen

Most mentalism acts are built on written information: names, words, drawings or questions that the audience writes and the performer seemingly cannot see. These three routines teach you to handle paper naturally and to build a reveal that lands.

5. Real or Fictional

Finding one special name among many is one of the oldest effects in mind reading. The séance-era version, the living and dead test, asked people to think about someone they had lost. We do not perform it and we do not teach it: a show should never lean on anyone's grief. This version keeps the same classic torn-paper principle and swaps the theme for something light. It needs nothing but a sheet of paper and a careful tear.

Routine

Real or Fictional

Level
Intermediate
Setup
None
Running time
5 minutes

The effect

A spectator writes the name of one real, famous person and several fictional characters, each on a separate slip. The slips are folded and mixed while you look away. You pick out the one name that belongs to a real person.

You need

  • One sheet of paper
  • A pen
  • A hat, bowl or bag
  1. Tear the sheet

    Fold a sheet of paper into thirds both ways and tear it into nine pieces along the folds. Hold the pieces so you know where the center piece is.

  2. Hand out the slips

    Give the spectator the center piece first and ask them to write the name of a real, famous person they like: a singer, an athlete, a scientist. Then hand them edge pieces for the names of fictional characters from films, books or cartoons (in practice, four or five are plenty).

  3. Fold and mix

    Have them fold each slip in half twice and drop all of them into the hat. Turn away while they mix.

  4. The selection

    Reach in (or tip the slips onto the table) and feel or look at the edges. The center piece is the only one with four torn edges; every other piece has at least one smooth, straight edge from the side of the original sheet.

  5. The reveal

    Discard the fictional names one by one, reading each aloud and saying it feels "made up". Hold the last slip, pause, and hand it over for them to open and read the real name.

Presentation notes

Keep the theme light. Ask for someone famous, never a friend, a relative or anyone private, so nobody has to share something personal in front of the room. Present it as a game of reading how people write and react, not as a psychic sense. If you want a more personal version later, the same principle works with a favorite place among invented ones.

Diagram of Real or Fictional. A sheet folded into thirds both ways is torn into a 3 by 3 grid of nine pieces. The eight edge pieces each keep at least one smooth, straight edge from the side of the sheet and carry the names of fictional characters. The center piece is torn on all four sides and carries the name of the real, famous person, so it is the one slip you can find by feel or by sight.
Only the center piece has four torn edges.

6. The Magician's Choice Prediction

Equivoque, or magician's choice, is a verbal technique that leads someone to a predetermined item while they believe they chose freely. It is one of the most useful tools in mentalism because it needs no gimmick, only control over your wording.

Routine

The Magician's Choice Prediction

Level
Intermediate
Setup
2 minutes
Running time
3 minutes

The effect

Three objects sit on the table. The spectator eliminates them one by one until a single object remains. You open an envelope that has been in view the whole time: it names that object.

You need

  • Three different objects (a coin, a key, a ring)
  • An envelope with a written prediction: "You will choose the key"
  1. Set the scene

    Place the envelope in view and the three objects in a row. The key (your target) goes in the middle.

  2. First choice

    Say: "Point to any two objects." If they point to two that include the key, remove the third. If they point to the coin and the ring, say "Fine, we'll get rid of those" and remove them. The key is left.

  3. Second choice

    If two objects are left, say "Hand me one." If they hand you the key, say "This one, then" and set it apart from the others. If they hand you the other object, say "So we're left with this one" and point to the key.

  4. The reveal

    Recap only what happened, in plain words: "You pointed to two, then you handed me one." Do not tell them they could have ended anywhere or ask them to confirm a free choice: the path was shaped, and an honest script never claims otherwise. Then have them open the envelope and read the prediction aloud.

Presentation notes

The whole method lives in phrases like "point to two" and "hand me one", which can be interpreted as either keep or discard. Never use the words keep or eliminate before you know which outcome you need. Rehearse every branch aloud until each sounds like the only thing you could have said.

7. The 1089 Book Test

Book tests are among the most admired effects in mentalism because a book seems to hold thousands of free choices. This one combines a book with a famous number force that has been printed in recreational maths books for generations.

Routine

The 1089 Book Test

Level
Intermediate
Setup
5 minutes
Running time
5 minutes

The effect

A spectator invents a three-digit number, does some arithmetic on a calculator and turns the result into a page and a word in a book you never touch. You name the word.

You need

  • A paperback of your own with at least 110 pages
  • A calculator or a phone
  • Pen and paper
  1. Prepare the book

    Open your paperback at page 108 and memorize the ninth word on the page. Choose a book where that word is a noun or something easy to picture.

  2. Make a number

    Ask the spectator to write any three-digit number whose first and last digits differ by at least two, for example 742. Then reverse it (247) and subtract the smaller from the larger (495).

  3. Reverse and add

    Ask them to reverse that answer (594) and add the two together. The result is always 1089. If they ever get 99, they forgot to treat it as 099; the reversal is 990 and the sum is still 1089.

  4. Find the word

    Say: "Use the first three digits as a page number and the last digit to count words along the first line." Hand them the book: page 108, word 9.

  5. The reveal

    Don't simply say the word. Describe it first, its shape, a feeling, a letter, and arrive at it slowly, as if the picture is getting sharper.

Presentation notes

Let the spectator do all the arithmetic on their own calculator while you turn away. Your distance from the numbers is what makes the effect impossible to reconstruct afterwards.

Advanced Mentalism Tricks

The last two routines are where mentalism stops being a puzzle and becomes a skill. Expect to rehearse each for a few weeks before you perform them for strangers. Both are documented across the classic literature and both are the basis of material professionals still perform today.

8. The Center Tear

The center tear is the foundation of billet work, the craft of learning what someone wrote on a small slip of paper. It looks like you destroy the paper; in fact you keep the one piece that matters.

Routine

The Center Tear

Level
Advanced
Setup
2 minutes
Running time
4 minutes

The effect

A spectator writes a name or a word inside a circle, folds the slip and you tear it to pieces without opening it. You then reveal what they wrote.

You need

  • A square slip of paper about 3 by 3 inches with a circle drawn in the middle
  • A pen
  • An ashtray, bowl or bin for the pieces
  1. The writing

    Hand the spectator the slip and ask them to write a word or a name inside the circle, then fold the slip in half and in half again, writing inwards.

  2. Find the center

    Take the folded slip. The center of the original sheet is now the corner where both folds meet. Turn the packet so that corner is at the top right (for a right-handed tear).

  3. The tear

    Tear the packet in half, put the pieces together, and tear again. Your fingers pinch the corner that holds the folded center. As you drop the pieces into the bowl, your hand keeps that small square curled out of sight.

  4. The glimpse

    Find a natural moment to open the center: reach for a pen, put your hand in your pocket for a lighter, or turn to write your impressions on a pad with the piece hidden behind it. A one-second look is all you need.

  5. The reveal

    Discard the center piece in your pocket. Then reveal the word slowly, starting with impressions and ending with the exact word.

Presentation notes

Rehearse in front of a mirror until the tear is relaxed and quick. If your hands hesitate at the moment of the steal, people remember the hesitation. Many performers practice one hundred tears before showing the routine to anyone.

9. Finding a Hidden Object

Contact mind reading, also called muscle reading or Hellstromism after the German performer Axel Hellstrom (1893 to 1933), uses the tiny, unconscious movements people make when they think about a direction. It is the closest thing in mentalism to a genuine skill of reading people, and it is the reason this routine sits at the top of the list.

Routine

Finding a Hidden Object

Level
Advanced
Setup
None
Running time
5 to 10 minutes

The effect

While you wait outside, the group hides a ring somewhere in the room. You come back, lightly hold a volunteer's wrist, and walk straight to the hiding place.

You need

  • A small object, such as a ring or a coin
  • A room with a few hiding places
  1. Choose a guide

    Pick the person who hid the object. Ask them to concentrate on the location and to think only of directions: left, right, forward, stop.

  2. The contact

    Hold their wrist lightly with your fingers, their arm slightly in front of you. Ask them to stay relaxed and to walk with you.

  3. Walk and feel

    Start walking slowly in one direction. When you head the wrong way, you will feel a slight resistance or drag. When you head the right way, the arm moves with you more freely. Change direction until the resistance disappears.

  4. The stop

    As you approach the place, the guide tends to slow down or tense up. Stop, move your free hand slowly over the area, and feel for the same tension as you get closer.

  5. The find

    When the arm stiffens, reach in and pick up the object.

Presentation notes

Start with large targets (which of four corners of a room) and work down to small ones. Explain openly that you are reading unconscious muscle movements: it is true, it is fascinating, and it frames you as a skilled performer rather than a psychic.

How to Perform Mentalism Tricks Well

Learning the method is the short part. These are the habits that separate a puzzle from a performance.

Perform One Effect, Not Five

Mentalism weakens with repetition. Three strong minutes followed by a change of subject leaves people talking. Twenty minutes of tricks invites them to look for patterns. Pick the routine that suits the moment and stop while they still want more.

Make It Look Difficult

A magician's effect can be instant; a mind reading effect should look as if it costs you something. Hesitate, get a detail slightly wrong and correct it, describe before you name. The struggle makes the result feel earned and real.

Frame It Honestly

Tell people you use psychology, observation and showmanship. Audiences enjoy the mystery just as much, and you never risk misleading someone who is vulnerable. Never use these methods to give advice about health, money or relationships.

Add Props Later

Once you can perform three routines from this page, specialist props become worth the money. Our list of the best mentalism tricks you can buy explains what each classic prop does without exposing the secret, and the guide to ESP cards shows how the five-symbol Zener deck can carry a full telepathy routine.

Where to go next: the full study plan on how to learn mentalism step by step.

The best mentalism tricks combine a simple method with a strong, personal reveal. Classic examples are book tests, finding one name among many, billet reading with the center tear, and contact mind reading. For a beginner, a number force like 1089 inside a book test gives the strongest result for the least practice.
Mentalists guess what people are thinking through a mix of methods: forces that limit the choice without the person noticing, written information they secretly learn, codes with a partner, and careful observation of body language. The performance hides which method is at work, so the result feels like mind reading.
Yes. Anybody can learn mentalism, because the core methods rely on psychology, arithmetic and practice rather than talent. What takes longer is the presentation: speaking clearly, reading a room and staying calm when a routine misses. Most people can perform a first self-working effect within an afternoon.
A beginner can learn mentalism by mastering one self-working routine, performing it for friends, and only then adding the next. Pair practice with a classic book such as Practical Mental Magic or 13 Steps to Mentalism, and study the psychology behind forces and cold reading as you go.
Learning a single mentalism trick takes anywhere from ten minutes for a number force to several weeks for the center tear. Becoming a confident performer with a short act usually takes months of regular practice, and professionals keep refining their material for years.
Yes. Many of the strongest classic routines, including the Clock Trick, Black Magic and the 1089 force, are in the public domain and taught freely in puzzle books, libraries and articles like this one. Paid books and props become useful once you want deeper material and more polished methods.
It is your choice with public-domain tricks like the ones on this page, but explaining a method usually spoils the moment for everyone who saw it. Never reveal the methods of commercial tricks or of working performers: those belong to their creators, and the magic community takes it seriously.
