About Blockfall.io

Blockfall.io is competitive block stacking against up to ninety-nine other players at once. Clearing lines sends garbage to opponents; taking garbage narrows your board until one bad placement ends the game.

Targeting matters as much as speed — you can attack the player closest to elimination, whoever is attacking you, or spread damage across the lobby. Solo practice with adjustable gravity is available any time.

How to play

  1. 1Clear multiple lines at once — singles barely register as attacks.
  2. 2Keep a clean well on one side for the long piece rather than stacking flat.
  3. 3Set your targeting mode before the match: badges rewards knocking out threatened players.
  4. 4Hold a piece early when the queue offers nothing useful; a wasted hold is cheaper than a hole.
