Color Sort Shelf

How to play

Gather each colour onto a shelf of its own — every shelf ends up empty or holding four of one colour. Each item has a colour and a shape. Tap a shelf to pick up its top group (the run of matching items on top), then tap another shelf to move it there. A move needs room, and the destination must be empty or have the same colour on top; as many as fit move. Undo is free of rules but counted, and every move you make counts, even one you undo. Tap only, no dragging.
