Pi

Pi is based on an original game concept because it is both a 3D racing arcade game, a platform game, a puzzle game and a first-person shooting game in one for Windows. The player can go through eras such as ancient Egypt, medieval and sci-fi worlds to unlock the mysteries of the Pi number.

• A platform game: you will have to jump and drive smarter on static and moving platforms to reach some inaccessible gems
• A puzzle game: some obstacles are more difficult than others because you must first understand the puzzle and then find out how to solve it
• A first-person shooting game: kill enemies!...
