Ball tower Puzzle

A wooden puzzle that plays like a sliding tile puzzle built in three dimensions. Colorful wooden balls in four colors fill a column of stacked, rotating discs, all but one slot, since a single empty space is what makes the whole thing move: balls slide up or down within their column into that gap, and twisting a disc shifts a ball sideways into a different column. The goal is to work the balls around, one slide and turn at a time, until every ball of a single color lines up together in one row, while the other three colors stay scattered elsewhere. Because moving one ball changes what's possible next, solving it takes real forward planning rather than random shuffling, the same thinking a classic sliding puzzle demands, just wrapped around a cylinder instead of flat on a board. Crafted in Germany from beech, with a smooth, close-fitting turn to every disc, it holds up to being scrambled and resolved again and again. A compact, quietly clever puzzle for focused hands ages 6 and up.
