Blockability 3d is a puzzle about space. Pieces made of cubes fall into a well, away from you. Move them, turn them and drop them so they fill whole layers. A full layer disappears and everything above it sinks one layer deeper. When the well fills to the top, the game is over.

  • Three ways to turn a piece. Spin, Roll and Tip let you stand any piece up, lay it down or turn it around. The landing guide shows where it will settle.
  • Classic: play until the well tops out. The pieces fall faster every 180 points.
  • Timed: three minutes on the clock. Place as many cubes as you can.
  • Descent, the story mode: Level 1 plays here. Levels 2 to 9 are one purchase at blockability.ai.
  • Every cube is a point. Your ten highest scores per mode stay in your browser, and finished games go on the daily and all-time boards under a name the game makes up for you.
  • Play your way: keyboard, mouse, touch or gamepad. Tilt the view to peek down the well.
  • Made for everyone: colour-blind and high-contrast colours, a reduced-motion setting, menus that work with the keyboard alone, and 19 languages.

The game counts plays, levels and scores anonymously (Google Analytics) and collects no personal information: privacy.
