Description
Math21 is a card game where you are given five cards and your job is to combine them using the four arithmetic operations and get the result 21.
Solve ten hands (an entire deck of cards) as fast as possible and get your scores on the leaderboard!
As a side effect you will hone your math skills and become smarter, faster, more successful, and better looking.
Some combinations of five cards are unsolvable in this game, these combinations are of course never given in the game.
The free version includes a practice mode only, the full version is available as an In-App Purchase.
