Ball Sort

Sort colored balls so each non-empty bin contains balls of only one color.

Rules

• You can pour from one bin to another.
• You may pour onto any bin that is not full (including empty bins).
• Each bin has capacity 4.
• Goal: all non-empty bins are full and monochrome.

Difficulty

• Easy: 5-7 full bins + 2 empty bins
• Medium: 9-12 full bins + 2 empty bins
• Hard: 13-17 full bins + 2 empty bins
