About ChromaOracle
The story behind our free color-sort puzzle solver engine
Our Mission
ChromaOracle is designed to solve color-sorting tube games — including Water Sort, Ball Sort, Nut & Bolt Sort, and Hoop Sort — instantly, efficiently, and accurately. We believe in building clean, fast, privacy-respecting web tools that deliver the shortest mathematical path with zero fluff.
Instant BFS Engine
Employs Breadth-First Search (BFS) graph traversal to evaluate state trees level by level, guaranteeing the global minimum move count.
Mystery Mode
Handles levels with fogged or hidden blocks by evaluating all valid state permutations and generating guaranteed safe moves.
100% Free & Private
No account creation, no app downloads, no tracking of personal identity data. Works directly inside any mobile or desktop web browser.
How the Solver Works Under the Hood
Color-sort tube puzzles can be formalized as state graphs where each node represents a tube arrangement and each directed edge represents a legal liquid pour or piece transfer.
We prune symmetric tube configurations and identical color paths, reducing search space size by up to 90% on 14+ tube boards.
Supports liquid pour physics (Water Sort), single sphere transfers (Ball/Hoop Sort), and variable height capacity (Nut & Bolt Sort).
