An 8×8 board, familiar pieces, and one question that keeps changing — what counts as a clear this time?
Fill rows and columns to reach each Stage target. Between Stages, choose one of up to three Shift Cards to shape your Run. Add diagonal or 2×2 clears, change the pieces you receive, earn more from consecutive clears, or make room on a crowded board.
Your Run has two rule slots. Once both are full, applying a new rule card means choosing which existing rule to replace. Other card effects, such as scoring bonuses and changes to the pieces you receive, can stack alongside those rules. Those choices shape your Run.
Good to know:
- Piece supply considers your board to reduce unnecessarily harsh draws.
- In new Run and Classic games, a placement that clears only single-color lines earns double the score.
- Learn the basics and Rule Shifts across 30 Missions, or keep playing in endless Classic mode.
- Share your result with friends.
No forced ads while you are placing blocks. Rewarded ads appear only when you choose an optional benefit, such as a Reroll. Interstitial ads may appear when you choose to play again after finishing a game.
BLOCKBOUND is free to play and includes ads.
We can't promise every board can be saved. We aim to make the pieces you receive feel fairer.
Use Shift Cards to reshape clear rules in a fairer 8×8 block puzzle run.
