math game that the whole family can enjoy. Fast, fun, and insanely addicting,
this lightning-quick card game will have you working
that mental math magic as you race to find creative equations hidden among
nine number cards. Keep what you find and collect the most cards to win!
Got the cards 2, 8, and 10? Concoct an equation like 10 - 2 = 8!
Working with the cards 2, 5, 5, 10, and 20? Conjure up a beauty like 5 + 5 = 20 ÷ 2 = 10!
Allowing you to use almost any math symbols and all sorts of crazy equations, Proof! is unlike most math games: it's engaging for both students in a classroom and adults at a party.
Proof! is also the inspiration behind our infamous, free, online game, the Weekly Challenge Math Puzzles. For the more puzzle-minded players out there, each week we post a new set of nine cards that hides a challenging equation. See if you can find the proof!
Full instructions for the card game can be found here.
Proof! was created by The Master Theorem Games in New York City and is now available for purchase. It is for 2 - 6 players, ages 9+, and takes less than 15 minutes to play.
Our flagship game, Snippets, was first successfully funded by over 400 word-loving backers on Kickstarter in November 2016.
