Diamond and Ruby app for iPhone and iPad
Diamond and Ruby is a game where you win if the gems can keep moving. If the gems cant move, the pennies win.
Pennies and the ruby make simple orthogonal moves, and the ruby captures by jumping. The diamond moves like a chess knight, and the diamond captures by going over a penny to another penny.
The different ways the gems capture, plus the numerous pennies, means the game has a continuous flow.
