Pyraos

From the developer: "You and your opponent set about building a pyramid, understanding that whoever places a piece on top wins the game. Sounds easy, right? Couldn't be more wrong. What sounds straight-forward turns boggling quickly: there are devious patterns you can build within the pyramid to force your opponent to use up his pieces too quickly. And, of course, the computer opponent is pretty tricky itself. Pyraos offers addictive game play, beautiful pre-rendered 3D graphics--including alpha blending, even on your 256-color handheld device!--and loads of fun."
