Fun Number-Guessing Magic Tricks! A Collection of Easy Ideas (21–30)
Calculation magic that results in 6
It’s a magic trick I like to show when I want people to get interested in numbers.
In this trick, you create equations that always come out to 6.
For example, if you insert plus signs into “2 2 2,” the equation works and equals 6.
Or if you insert multiplication and subtraction into “3 3 3,” the answer also becomes 6.
By inserting symbols like this, you neatly complete the equations and calculate as if by magic.
If you’re interested, try coming up with your own equations too.
You can do calculations with playing cards!? Simple playing-card magic
In this magic trick, you do a calculation using two selected playing cards.
For example, let’s say the selected cards are a 6 and a 2.
Add 6 and 2 to get 8… then when you turn over the 8th card from the top of the deck, an 8 will appear.
This is a self-working trick, meaning it requires no sleight of hand.
By placing the 4, 8, Q, and 3 at predetermined positions in the deck beforehand, doing the math will make the correct card appear from the deck.
At the beginning, you show three cards, but in fact all three are 6s—and the next three cards are all 2s!
A magic trick where you guess the number someone rolled on a die!
Here’s a magic trick using dice.
Prepare three dice and have someone roll all of them once.
Ask them to remember the total of the numbers shown.
Next, flip two of the dice to their opposite faces and add the new numbers to the original total.
Then hide one of the flipped dice, roll the remaining dice again, and have them remember the new total after adding the numbers shown.
The magician will guess this final number.
The method is simple: just add 14 to the sum of the numbers showing on the two dice that aren’t hidden.
Number Guessing Card Magic
I’ll introduce a magic trick that uses playing cards to find a spectator’s chosen card.
This one requires almost no sleight of hand, so just learn the steps and practice to perform it smoothly.
First, have a spectator choose any card.
Return that card to the deck, then deal the cards onto the table one by one into three groups.
Ask the spectator to confirm which group contains their chosen card.
Repeat this process three times.
After the third round, the chosen card will inevitably end up in the middle of its group, so finish by making that card dramatically pop out to surprise your audience.
The answer is always 3!? A mysterious calculation
Have the audience think of a favorite number, then follow your instructions to calculate.
First, add 1 to the number they thought of.
Next, double that result and then add 4.
After that, divide by 2, and finally subtract the original number they thought of… Did the answer come out to 3? With this curious calculation, no matter what number they start with, if they follow the steps correctly, they will always end up with 3.
Since the audience likely doesn’t know it will be 3, reveal that you had predicted the number after they get their answer to amaze them.
