Could you add together five completely random three-digit numbers in less than two seconds?
With Speed Math Dice, that's exactly what your audience will believe you can do!
Hand your spectator five specially designed dice, each displaying a selection of three-digit numbers. They freely roll all five onto the table and you ask them to add together the numbers showing on the top faces.
While they're still reading the numbers or reaching for their phone calculator, you calmly announce the correct total almost instantly!
No superhuman mathematical ability required – just a wonderfully clever secret that creates the appearance of astonishing mental calculation skills.
đ˛ Give the spectator five specially designed number dice
𤲠They freely roll all five onto the table
đĸ Five different three-digit numbers are now visible
đą Challenge them to calculate the total
⥠Before they've finished entering the numbers into their calculator, you announce your answer
đ˛ The total is completely correct!
Repeat the experiment with another roll and you can apparently do it all over again.
You don't need to be a mathematical genius or memorise hundreds of combinations.
Speed Math Dice uses a clever mathematical principle that allows the performer to determine the total extremely quickly once the secret is understood.
To your audience, however, it looks like you're performing incredibly complicated mental arithmetic almost instantaneously.
The result is a simple but extremely effective piece of mentalism that audiences immediately understand.

One particularly entertaining presentation is to challenge your spectator to use the calculator on their phone.
They roll the dice and begin entering each three-digit number...
But before they've even finished typing them in, you've already announced the answer!
The calculator then becomes the spectator's own independent way of confirming that your apparently impossible calculation was correct.
