Hachi Block is a combo-focused Tetris-based puzzle game, created in 72 hours.  Score high by dragging blocks into a grid and creating a three-in-a-row horizontal or vertical block formation.  Stay alert, however; don't let the blocks rise to the top of the screen!

To score as high as possible before the blocks stack to the top of the screen.

First, click on the 2x2 blocks on the right side of the screen to pick it. While dragging this piece, right-click or press space to rotate this block. Click anywhere (yes, anywhere; even on top of existing blocks) on the grid of blocks to drop the piece.

When 3 or more same-colored blocks are matched vertically or horizontally, those blocks will be eliminated, and points will be awarded.

Remember that each move will cause more blocks to drop from the top of the screen. If any blocks remain on the top of the grid, it's game over!


  • v00 - Initial release. May or may not work based on compilation issues while building.
  • v01 - New platforms: WebGL, Linux, Mac now supported.
  • v02 - Fixing difficulty settings not progressing correctly.  It was literally a single-character typo.  Also fixed an oddly-angled block.
  • v03 - Fixing the mute buttons in the audio options to actually mute the music/sound effects, rather than making them really quiet.
