2048 3D: Merge Cubes

Stone blocks in a 2048 game sounds like a rules violation, but that's exactly the twist here. Numbers still drop and merge the way you'd expect, doubling from 2 all the way toward 2048, but every so often a stone lands that refuses to combine with anything. You either work around it or blast it away.

That's where the boosters earn their keep. X2 doubles any block's value on the spot, Bomb clears out everything nearby, and Flash wipes every stone off the field in one go. Swipe left or right on empty space, or drag with your mouse on desktop, to slide a block into position, then let go to drop it.

The pressure comes from above, literally. Stack blocks past the top boundary and you've got three seconds before it's game over, so every merge decision doubles as damage control. It's a tighter squeeze than most Arcade games, and if you're into cube-based challenges, check out Cube Games for more of the same energy.

Free, no download, runs right in your browser on Android, iOS, or desktop.

Merge matching number blocks to build higher values and rack up points while clearing each level before the stack overflows.

Swipe left or right on an empty part of the screen to slide the falling block into place, then release to drop it. On desktop, hold the left mouse button to drag and let go to drop the same way.

Stones can't be merged, so save your X2, Bomb, or Flash boosters for when they start clogging the field. And don't let blocks pile above the top boundary for more than three seconds, or it's game over.
