◎ Play checkers

How strong Easy Sees a move or two ahead and often gives pieces away. Medium Spots simple shots and rarely leaves a piece hanging. Hard Looks eight moves ahead and sets up two-for-ones. Expert Thinks as deep as a second and a half allows. Very hard to beat. The computer plays in your browser and answers in a moment (Expert takes a second or two). These games have no clock and don't count in your record against people.

Opponent Leave it empty and the game is an open seat on the Games page: the first member to take it plays you.

You play Either (a coin decides) Red pieces (moves first) White pieces

Days per move Each move gives the other player this long to answer. Run out and you lose on time (after ten moves each; before that the game is just set aside).
