Mathcentration marries an old card game Concentration with the four basic mathematic functions (addition, subtraction, multiplication and division). The two cards in view must match the number at the top of the playing grid based on the mathematical function in use. Players can select which math function they want to use along with the number of cards in play and the highest value on the card. The game can get fairly difficult when setting to the maximum values.
Mathcentration is ad supported with the option to upgrade to the ad-free version.
