Win Conditions
Checkmate
The most common way to win. Your opponent's king is under attack and cannot escape, block, or capture the attacking piece.
Resignation
A player may resign at any time, conceding the game to their opponent.
Timeout
If a player runs out of time on their clock, they lose the game (with some exceptions - see below).
Draw Conditions
Stalemate
The player to move has no legal moves, but their king is NOT in check. The game is a draw.
Insufficient Material
Neither player has enough pieces to deliver checkmate. Common examples:
- King vs King
- King and Bishop vs King
- King and Knight vs King
50-Move Rule
If 50 moves pass without a pawn move or capture, either player may claim a draw.
Threefold Repetition
If the same position occurs three times with the same player to move, a draw can be claimed.
Agreement
Both players may agree to a draw at any time.
