Devil Dice

Devil Dice (Xi, pronounced "Sai", in Japan) is a video game for the PlayStation. It was originally created by developer Shift on the "homebrew" Yaroze platform, and later turned into a commercial game. Released in 1998, it is one of only a handful of games to make the leap from the Yaroze to commercial release. The game is a million-seller and a demo version was released as a PlayStation Classic game for the PlayStation 3 and PlayStation Portable (PSP) on November 7, 2007.
A sequel, Xi Jumbo was released on the original PlayStation in Japan and Asia. The "Jumbo Mode" gameplay changes were integrated into Bombastic on the PS2.
A version called Xi Little also appeared on the Wonderswan Color.
A PSP version, Xi Coliseum, was released in Japan on March 9, 2006. This version includes support for ad hoc wireless play between up to five players.
Bombastic, for the PlayStation 2, is the second sequel to Devil Dice, and incorporates all play modes from previous releases.
