Fun Number-Guessing Magic! A Collection of Easy Ideas (11–20)
A simple mentalism-style number-guessing trick
It’s cool to read someone’s mind and guess their number, right? That’s called mentalism, and mastering it isn’t easy, but a mentalism-style number trick is something you can learn right away.
First, have the audience silently think of any number from 1 to 10.
Next, ask them to double the number, then add 15, and divide the result by 2.
Finally, have them subtract the original number they first thought of.
Now all that’s left is for you to guess the result.
In fact, no matter which number they chose, the answer will be 5.
Guessing the numbers after tearing up the paper they were written on
Magic that feels like psychic powers is fun, isn’t it? Here’s one I recommend: a trick where you tear up a paper with a number written on it and still guess the number.
First, have someone write a three-digit number on a sheet of paper folded into quarters.
Then fold the paper again and tear it into small pieces.
After that, you reveal the correct number.
The secret is that before tearing, you slip the paper under the table, fold it the opposite way, take it back out, and tear it while secretly looking at the number.
They’ll be left thinking, “How did they know even though it was shredded?”
A calculation magic trick where the numbers predicted in advance appear exactly as foretold
This magic trick predicts a number that equals the sum of three three-digit numbers.
First, have the spectator name any three three-digit numbers.
Right before adding them up, you make a prediction—but at this stage, the sum and your prediction won’t match.
Then, you split each of the three-digit numbers into their individual digits, form three new three-digit numbers from those digits, and add those.
Amazingly, the total now matches your prediction! The key is to take the original three numbers, break them into digits, and use the sums of corresponding digits.
If you love numbers, practice this and give it a try!
Even elementary schoolers can do it! Guess the trump card numbers
This is a playing card magic trick where you guess the card someone has chosen.
In this trick, the spectator returns their chosen card to any spot they like, and you pretend not to know where it is—but in fact, from the moment it’s returned, the performer already knows its location.
The key to making this trick work is the bottom card of the deck.
While squaring the deck and demonstrating that the cards are well shuffled, make sure to firmly remember what that bottom card is.
Then, at the moment the chosen card is returned to the deck, place the key card directly on top of it.
By doing this, you’re able to keep track of the position of the chosen card!
Read Your Mind! Math Magic
First, choose a number from 1 to 9.
Then add 1 to that number and multiply by 2, then add 6 and divide by 2.
Finally, subtract the number you originally chose, and you’ll end up with 4.
It’s a magic trick where no matter which number you pick, the final result is always 4, so as long as you remember the steps, anyone can perform this prediction trick successfully.
As long as the arithmetic or mathematical expression holds, you can change the content and arrange it in different ways, so why not come up with your own version?
