Ball Stacks is an online ball sort puzzle where you group colors into matching stacks using as few moves as possible. Start with beginner-friendly collections, jump into Survivor-inspired variants, or open a custom level to practice deeper move planning.

The Challenge from Season 47 episode 11 of Survivor.

Keep Ball Stacks light and readable by building clean bottom anchors, avoiding fake home columns, and preserving enough space to untangle a board.
