Whack-A-Math

Play WhackAMath - based on an idea by Klemens Winkler - a fun arithmetic challenge to keep you on your mental toes! Select the operations that will combine the rolled dice to a number you can click, then take that number off the board. Remove as many numbers as you can! Not hard enough? Click the gear button to change settings - choose a larger board, or score yourself, or play against the clock!  Post your score if you are proud of it!

Play it on your computer, tablet or phone!

Multi-player version coming soon for registered together.math users!

Rules of the game

"Warmup" mode

  • Just press "start" and go! 

  • Click on the mathematical operations between the dice (initially "+") to select the operation you think will work.

  • Click on the parentheses left or right to group operations the way you want them.

  • Drag and drop the dice into a different order if you want to.

  • When you are done, click the number you think is the result of the operation. It will disappear and the dice are rolled again.

  • Continue until you wipe out the board!

  • But not every dice roll is solvable ... click "roll" when you want different dice.

"Game" mode

  • Now we keep score:

    • 1 point for an even number (>2)

    • 2 points for an odd number

    • 3 points for a prime number

"Speed" mode

  • Now it is a race against the clock:

    • Every dice roll is good for 30 seconds

    • Your score is multiplied by the number of seconds you had left

    • A wrong click will cost you ...

    • Rolling again when there was an achievable solution will also cost you ... and the less time you had left, the more it will cost you

    • Try not to stress out (and if you succeed, let us know how you do that!)

"Settings" mode

  • Press the "gear" button by the dice

  • Click the number of tiles you want to play

  • Click the mode button by the tile numbers to select the mode you want to play

  • Click "play" to exit settings mode

We hope you will enjoy playing Whack-A-Math!

Oh and one more thing ...

"Cheat" mode

  • For the hacker in you:

    • Find the secret key and phrase

    • Unlock "only solvable dice rolls" and "achievable numbers are highlighted"

    • No, we won't tell you how to activate it
