Play Checkers Against the Computer

How This Mode Works

Select Play AI on the game board and choose a level. You control black, the computer controls red, and black moves first. The game responds after each completed turn; reply time depends on the position and device.

This page explains the four levels and the rules they share. The computer plays a regular game of American checkers. It does not use a separate ruleset or change the legal moves.

Four Difficulty Levels

• Easy: picks a random legal move. A forced capture remains required even at this level; the computer cannot skip a legal jump.
• Medium: the default setting. It searches possible replies before choosing a move, which can help it avoid some simple mistakes.
• Hard: searches further ahead than Medium. It may recognize more short tactics, though it can still miss a useful move.
• Expert: uses the deepest setting available here. Replies can take longer in complex positions.

All four settings follow the same board and capture rules. Level affects how the computer selects among legal moves, not which moves are allowed. If a jump is mandatory, each level must take one; if a sequence continues, it must finish the chain with the same checker.

Why Play Against the Computer

• Start a game without waiting for another player or arranging a match.
• Choose a lower or higher level for a practice session.
• Review a finished position, then start a fresh game when you are ready.
• Practice required jumps, multi-jumps, and king movement at your own pace.

The board always begins from the normal starting position. This mode does not load a saved puzzle or let you enter a custom position.

How the Computer Plays Checkers

At the start of its turn, the computer considers legal moves under the same rules as a human player. A capture is mandatory. If a piece can continue a jump, the turn must complete that sequence before the next side moves. Men move forward. Kings move one diagonal step, or capture by jumping an adjacent checker into the empty square beyond it, forward or backward.

The higher levels compare possible moves and replies before choosing. For example, they can consider whether a move leaves a piece available for an opponent's forced jump, or whether a capture opens another jump in the same chain. Before you move, count the legal replies you expect to face and see whether another checker can protect the landing square. This makes practice more useful even when the computer's reply is not the move you expected.

There is no move timer. The response time varies with the position and the device. The game stays in the browser, and a local save may restore the board when storage is available.

A checkers vs computer practice game is useful for learning the turn rhythm: make one move, wait for the reply, then inspect the board again. Look at the status line after a jump. It shows whether you must continue with the same checker or whether the other side can move next.

Another checkers vs computer session can focus on just one decision: list every available capture before you select a move. That habit makes it easier to notice a forced jump and avoid choosing a normal move when a capture is required.

Practice Mode

Use Easy to learn how legal moves highlight and how a capture chain works. Move up to Medium, Hard, or Expert when you want the computer to look farther ahead. If you change level during a match, the board resets to a new starting position.

There is no undo control and no way to switch colors during a game. In AI mode, you play black. To review another position, finish or restart the game. For the full rules, see checkers rules; for another person, choose two-player mode.
