SmartMines is a minesweeper game for Mac OS X (Tiger and above) with a few features that make it stand out when compared with many other minesweeper games. For instance, it features "smart clicks" that make it easy to both mark and uncover with single button mice. Also the minefield window is resizable, so actually hitting the square you want will not be the greatest challenge.

It should compile under any operating system supported by SDL, SDL_image, and SDL_ttf. The symbols on the screen represent a numeric value in the order they are displayed on the right.

Hex-a-hop is a puzzle game based on hexagonal tiles. There is no time limit and no real-time elements. The objective is simply to destroy all the green hexagonal tiles on each of the 100 levels.
