Suberi December 2024
A new sliding puzzle game with a database of over seven million computer-generated puzzles.
Suberi is a new sliding puzzle game with familiar mechanics. Pieces can move up, down, left, or right, but they keep sliding until they hit a wall or another piece. The puzzle is solved when all of the target squares are covered by the correct pieces. These simple rules make Suberi a superset of the 15 Puzzle, Lunar Landing, and Ricochet Robots. The name means something like "sliding" in Japanese.
As with my Rush Hour project, I did more than write a simple puzzle solver. I wrote some C++ code that enumerates all kinds of boards and finds the hardest possible starting positions for each one. The result is a database of over 7 million puzzles with board sizes ranging from 3x3 to 5x5. The hardest one requires 232 moves to solve!
The website is still a work in progress, but you can play through several puzzle packs, search the entire database, or even create your own puzzles.
