Box Tap Sort

A cube that doesn't match one of your color orders goes into your holding bin. The bin has 7 slots. Fill every slot and the current puzzle resets, so a few careless taps can cost you the whole structure.

It's a head-to-head race. You need to clear more structures than your rival before time runs out. Each structure is cleared by tapping every cube in it, following the color orders shown at the bottom of the screen.

There are three at any time. Each one is a color you can tap, with a count of how many cubes of that color you still need. Tap exposed cubes that match one of them to take the stack apart.

Your holding bin has 7 slots, and every wrong-colored cube takes one. When all 7 are full, the current puzzle resets. So you have some room for mistakes, but not much.

Yes, you can drag to rotate. It helps because you can only tap cubes that are exposed, so turning the structure lets you spot the ones you need.

It's a head-to-head puzzle, so you're racing a rival to clear more structures before time runs out. The page doesn't describe how that rival is matched, so expect a race rather than a relaxed solo solve.

It's free and runs in your browser on desktop, so there's nothing to download. Open the page and start tapping cubes.

Box Tap Sort comes from developer Golem Kin Games. It's a 3D color-sort puzzle played in landscape orientation.
