Devil Dice (known in Japan as XI, pronounced [sai]) is a puzzle video game developed by Shift exclusively on PlayStation. It was released by Sony Computer Entertainment in Japan in 1998 and Europe in 1999, and by THQ in North America in 1998. 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 7 November 2007.^[3]

Gameplay

Devil Dice is a unique puzzle video game, where the player controls a small devil that runs around a grid covered in large dice. The player can both stand atop dice, and stand on the ground (with the dice towering above). When standing on the dice, the player can move from die to die, or can roll a die in the direction he or she runs, revealing a different face as the die rotates. Creating a group of adjacent dice with identical pips—the size of which must be at least the number of pips—causes those dice to slowly sink into the field before disappearing. Chain reactions are possible by adding additional dice to a sinking set. Different types of dice are available in some modes, with different properties to make the game more challenging.

The game features the following modes:

• Battle - pits the player against a single computer opponent, both attempting to build up chains and negate those of the opponent.
• Puzzle - mode in which players must solve puzzles (i.e., clear all dice) using only a limited number of steps or moves. Solving a whole row of puzzles allows players access to a picture that they can play on in Battle mode.
• Trial - the standard arcade-style mode, where the objective is to remove as many dice as possible (and thus score as many points as possible) before the grid completely fills with dice.
• Wars - quickfire multiplayer mode, supporting up to four simultaneous computer opponents, or five human players when using a multitap. Players damage each other as they complete chains, with the last man standing becoming the winner.
