JMineSweeper is similar to other minesweeper games in that you try to make the right choices, so you won't end up being bombed out of the game.
It's made for Mac OS X, so it has that look. You also get access to the high scores, and you can obtain post-game feedback. The Preferences and About windows have tooltips that explain some of the functions. Also, the rules of gameplay can be found in the About window.
