Stack Sort

Stack Sort is the satisfying sorting puzzle where every tap clicks something into place.

Each column wants one kind of thing — sea creatures, birds, fruit, sweets, tools, music, space. You're always holding one stamp. Tap a column and it slides in on top; the stamp at the bottom pops out and becomes the one in your hand. Trade by trade, mixed-up stacks turn into neat, sorted columns.

It sounds simple. Then you're three moves deep, planning what you'll get back before you commit, and the "just one more level" feeling kicks in.
