Block Sort Tower

A cozy sort puzzle where you move jumbled colored cubes between tower columns until each one is a single color. Tap a source tower, then a target, and the top block flies over onto a matching color or into an empty column, with three stars for solving in fewer moves. Forty levels ramp up with more colors and towers and nailed blocks that cannot move, and every level is generator-checked to be solvable. Boosts like an extra tower, an undo, and a hint help, bought with coins from clearing levels. A warm construction-site look of gold, wood, and glossy cubes, with no timers or pressure, just your brain and logic.
