A game of chess may end in a draw in several possible ways:

Agreement

When both players agree that neither can win, a game of chess can be declared drawn.


Stalemate

Stalemate is a situation where neither player is in check, but the player whose turn it is to move cannot do so legally.

The game of chess is drawn.


Repetition

If the same position for all pieces occurs multiple times throughout a game of chess, this is a draw.

The exact number of positions is dependent on the specific rules used, but $3$ is conventional.


Fifty Move Rule

If, during $50$ moves, no pawn has been moved and no capture has been made, either player may claim a draw.

This rule is not always used.


Insufficient Pieces

If neither player has sufficient pieces to force checkmate, then the game of chess is drawn.
