===Mathematical puzzles===
[[Mathematical puzzle]]s require mathematics in order to solve them. They have specific rules, as do [[multiplayer game]]s, but mathematical puzzles do not usually involve competition between two or more players. Instead, in order to solve such a [[puzzle]], the solver must find a solution that satisfies the given conditions.

[[Logic puzzle]]s and [[classical cipher]]s are common examples of mathematical puzzles. [[Cellular automata]] and [[fractals]] are also considered mathematical puzzles, even though the solver only interacts with them by providing a set of initial conditions.

As they often include or require game-like features or thinking, mathematical puzzles are sometimes also called mathematical games.
