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 they run, revealing a different face as the die rotates. Creating a group of adjacent dice with identical pipsâÂÂthe size of which must be at least the number of pipsâÂÂcauses 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:
According to lead designer Yuichi Sugiyama, Devil Dice was created for Game Yarà Âze, a Japan-exclusive competition where participants competed for access to a development environment for the creation of PlayStation games intended for commercial release. The original program was held between 1995 and 1999, with over 3,000 participants and 1,200 submitted game concepts. Ultimately, over thirty Game Yarà Âze titles went to market, including Devil Dice and the first Doko Demo Issyo game. One of the Devil Dice programmers, Shuichi Yano, stated that he was a successful applicant of the Game Yarà Âze program; he further stated that the program is unrelated to the similarly-named Net Yarà Âze program.
Devil Dice received favorable reviews according to the review aggregation website GameRankings. Both GamePro and Next Generation were positive to the game despite noting its high difficulty. In Japan, Famitsu gave it a score of 30 out of 40.
Famitsu reported that the title sold over 131,815 units in its first week on the market and approximately 864,844 units during its lifetime in Japan. GamesTM regarded it as one of "10 Underrated PlayStation Gems".
The game won the award for both "Best Puzzle Game" and "Best Multiplayer Game" at the 1998 OPM Editors' Awards. Hyper later named Devil Dice a second runner-up for "1999 Hyper Reader Awards" for "Best Puzzle Game", which went to Bust-A-Move 99 for PlayStation and Nintendo 64.
