KMines is another game offered by KDE. Beneath the square boxes are hidden mines. The object of the game is to locate all the mines as quickly as possible without uncovering any of them. If you uncover a mine, you lose the game. Simply put, it is a step above Minesweeper (for Windows, if you have played that already).
Apart from the usual gameplay, KMines offers themed interface (offers 3 themes) and a slightly better High Scores implementation. The game has three modes of difficulty – (i) Easy, (ii) Medium, and (iii) Hard.
Here are some screenshots of the game in action: –
