Repetition of Position Draws
Rules that make games end in draws if players make position or game states repeat themselves in a game instance.
Actions that players make in games are typically done to advance their positions or increase their chances of winning. However, when players meet each other in games their actions can cancel each out in ways that make the positions of game elements — or more generally, the whole game state — repeat themselves. Repetition of Position Draws are rules that make such sequences of actions result in draws instead of letting players potentially continue infinitely with the actions.
Wikipedia has a page on a specific instance of this, the Threefold repetition.

Examples
Game instances of Chess end if players make the same position occur three times (not necessarily in a row). Shogi does the same but allows repetitions up to four times before a draw is enforced.
Anti-Examples
Go forbids the direct repetition of an existing game state, and may forbid any repetition depending on which rule set is used.
