Water Color Sort – Order From Chaos
Water Color Sort looks simple—pour colored water so each tube holds a single color—but depth emerges fast. The key is staging: create temporary buffers, keep one tube empty as a universal swap, and avoid locking tall stacks with mixed bottoms. When stuck, undo the last consolidation and reopen space.
Planning Tricks
- Singleton buffer: maintain one empty tube to unlock dead ends.
- Bottom-first thinking: a wrong base color poisons the whole tube.
- Two-step pours: move A→buffer→target to keep options alive.
