The gameplay of Bombastic is similar to its predecessor, Devil Dice. Players control a family of small devil called Aqui that runs across a grid full of dice. Players can walk on the grid, pushing dice around, or walk on the dice, rolling them as the character walks. The objective and how dice are cleared vary between modes.

Devil Dice is a unique puzzle 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. 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 on November 7, 2007.

XI JUMBO was released as a sequel to Devil Dice only released in Japan. The rule is similar to its predecessor, but in this version, you can stack the dice vertically by lift up or jump with a die. The classical "Trial - Time Limited" and "Puzzle" modes are also available on this version. For new features, The "Battle" mode is entirely renewed with a garbage-attacking style. In addition, a new task-solving trial, named "Norma Attack," is introduced.
