Oct 08, 2011 - The independent development company codemachinery introduces Calx 1.0, for iOS devices. It is an puzzle/arcade game and fits best into the match3 category. It plays similar to the well-known Bejeweled, but still is different. In principle, the player has to select a simple math term (like 34 + 5) and then its solution - then a highscore awaits. Bonus factors get triggered, when a player can solve the math really fast. The game has iOS Game Center integrated and brings 18 new achievements.
