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.
KBall is a game of skill and reflexes suitable for all ages. The idea is to move a ball around the map without falling or running out of time, and getting the prizes, in order to reach the exit. The map has different traps, such as slides, pushers, jumps, falls, and walls, etc. Maps are viewed from top view, and the walls and player's ball are real-time rendered in beautiful 3D. There is a map editor available inside of the game, to make custom maps.
Petals on a Rose Game is a computer version of the famous riddle/puzzle game called Petals on a Rose. It is rumored that Bill Gates was stumped by it for two days. It's usually played with a group of friends and a set of 5 dice. The game master rolls the dice and tells everyone the answer. This computer version of the puzzle works similarly, only in this case the computer plays as the game master. There is no source included because that would give away the answer. The binaries were made as universal as possible.
