Checkers is a classic board game for iPhone that allows 2 players to compete against each other. The game follows the traditional rules of checkers, where players position their 12 pieces on the closest dark squares of the checkerboard. One player has 12 pieces of one color, while the other player has pieces of a different color.

The game starts with the player who has the darker pieces making the first move. Players take turns moving their pieces diagonally one square towards the opposite side of the board. If an opponent's piece blocks the path and there is an empty square diagonally beyond it, a player can jump over the opponent's piece and remove it from the board. If multiple jumps are possible from the landing square, the player can continue with a second jump.

In this app, there is an option to turn off the rule that requires a player to make a jump if it is possible. This allows for more strategic gameplay.

When a player's piece reaches the furthest forward row of squares on the opponent's side of the board, it gets crowned and gains the ability to move or jump in any direction diagonally.

The game ends when one player has lost all their pieces or is unable to make a move. Checkers is a free game, available on the iPhone platform, and is a great choice for fans of this classic board game.
