Description
Japanese SugarOffice and SCE dice puzzle, where the player rolls dice on a grid to remove them in groups. Created by SugarOffice and Sony Computer Entertainment, released in 1998 in Asia and Japan under the XI sai title. Grid-based 3D puzzle where the player rolls dice and stacks them in groups matching the top face value, over ten modes including Stage and Trial, two-player versus mode and playful ambient soundtrack. Asian and Japanese edition under the XI sai title.
Cult dice puzzler published by Sony, where you line up number combinations by rolling dice across a grid, here in its Asian edition. Its collecting interest comes from the singular place this original concept holds in the PS1 puzzle catalogue, never really imitated, and from the Asian version's thinner distribution compared with the more common Japanese runs. Sought by fans of inventive puzzlers and completists of the XI franchise.
An underrated gem
An isometric 3D puzzler as original as it is nerve-racking: you roll dice across a grid suspended over the void to align their faces, with the threat of falling ever-present. Released with no fanfare, it never enjoyed the spotlight of the genre's giants. Its clever concept and mounting tension make it a gem for fans of high-pressure brain-teasers.
Is XI [sai] still worth playing in 2026?
A Sony puzzle known in the West as Devil Dice, XI rolls dice across a grid where you must match identical faces to make them disappear, in a principle both simple and of unexpected strategic depth. The rolling mechanic, the space management and the addictive rising tension make it a fierce brain-teaser, excellent in multiplayer. The modest production matters little against the ingenuity of the concept. An original, demanding puzzle for fans of snappy thinking and scoring games.
