Checkers Free is a free application for playing the board game checkers on your iPhone or iPod Touch. You can play with one or two players (on the same device), or you can even watch two computer players compete in a demo mode.
In the one-player mode, you can adjust the difficulty of the computer opponent with a slider, and in both modes you can type in player names and choose which color goes first. Clean, wood-grain-themed graphics and simple sound effects give the game a more realistic feel, and an undo option allows you take back your last move. Checkers Free also lets you turn off sound effects, allow forced jumps, or even use the app's old interface.
Overall, this is a well-done app that's a great value for anyone who's a fan of checkers.
