Calcache, math puzzles

A playful puzzle to master addition and multiplication tables, Calcache is a game of jumbled operations: like "word search", but with numbers instead of letters, and additions or multiplications instead of words.
Start with the times table of 2 and try to unearth all the operations with the number 2 in the grid. Act fast, and you'll earn a speed bonus. Once you complete a table, the next one gets unlocked.
With Calcache, your children will quickly become unbeatable, and they'll be the ones asking you to review their tables.
