3D game
Tower Blocks is a one-tap stacking game with a calm isometric 3D look. A block slides back and forth above your tower, and you click, tap or press Space to drop it. Whatever overhangs the block below is sliced off and falls away, so the tower gets thinner with every sloppy drop. Line each block up precisely to keep it wide and keep climbing; miss completely and the run is over. Each game is quick to start and hard to put down, which makes it a good short break on a phone or a desktop. Sound effects are generated in the browser and can be muted with the speaker button. The game is open-source under the MIT licence and is hosted on Endless.

Only the part of the block that overlaps the one below stays on the tower; the overhang is sliced off and falls away. If you miss completely, the run is over and you can restart with a click, tap or Space.
