Cardmath Theory

Cardmath Theory is a puzzle game in which a deck of cards becomes a mathematical tool. An equation appears on the screen with empty slots and a known answer. Your task is to select cards from your hand so that the expression becomes correct. The numbers on the cards follow simple rules: cards from two through ten are worth their face value, a jack is worth eleven, a queen is worth twelve, and a king is worth thirteen. The ace holds a special place: it can be either one or fourteen, and the game automatically checks both possibilities, giving you more freedom in finding the solution. The game features four modes. The Levels mode offers 100 consecutive problems of increasing difficulty, which unlock as you progress. Quick Play consists of ten problems in a row, with one attempt per problem and a score at the end. The Timed mode tests your thinking speed: you have thirty seconds per problem, and a single mistake ends the round. Training mode lets you solve problems at your own pace without any pressure. The difficulty of the problems gradually increases: from simple addition to multi-step expressions involving multiplication, subtraction, and combinations of several cards. Cardmath Theory trains your logic, mental math skills, and ability to think outside the box.
