Block puzzle — free 8x8 grid game
A block puzzle gives you shapes to fit onto a grid, clearing any row or column you complete. Cube Clear is a free browser version on an 8x8 board: three pieces per turn, no timer, nothing falling, and the run ends when none of your three pieces fits anywhere.

How is a block puzzle different from Tetris?
The difference is time, and it changes the genre completely. In a falling-block game the piece is descending while you decide, so the skill being tested is partly execution speed — thinking correctly but slowly still loses. In a block puzzle nothing moves until you move it. You are handed three shapes, you place them wherever you like, and the board waits.
Removing the clock does not make it easier, it makes it a different kind of hard. There is no reflex to fall back on and no chance of surviving a bad decision by acting fast. Every game that ends, ended because of a placement you chose several turns earlier — which is uncomfortable in a way that a falling-block game never is.
How do you get a high score in a block puzzle?
By managing space rather than by chasing clears. The single most common way a run ends is a board that looks fine but has no room left for the largest piece in the set — usually the 3x3 square or a long bar. Once that shape is unplaceable you are relying on it not appearing, and eventually it does.
So the discipline is to keep at least one region open that can absorb the worst piece you could be dealt, and to break up holes of one or two cells before they multiply. Clearing several lines at once pays a combo bonus, but taking a small clear now to keep the board open usually beats holding out for a big one — a run that survives longer scores more than a run that scores prettily.
- Always keep one region that could take the largest piece in the set
- Fill from the edges inward; the middle is the hardest space to reclaim
- Single-cell holes are the real killer — plan the piece that closes them
- Refills come only after all three pieces are placed, so plan the whole turn
Where can I play a free block puzzle?
Cube Clear is free in the browser with no download and no account. You get three shapes per turn on an 8x8 grid, a green or red preview showing whether a placement fits, and a combo bonus for clearing several rows and columns at once. There is no timer and nothing falls — the only pressure is space.
If you like the spatial planning but want numbers rather than shapes, Neural Grid is the harder relative: you drag paths through connected number blocks to hit a target sum, and new rows push up from the bottom while you think. Both are free and both save your best score locally.
Frequently asked questions
How do you play a block puzzle game?
You are given three shapes per turn and place them anywhere they fit on the grid. Completing a full row or column clears it and scores points, and clearing several at once pays a combo bonus. New pieces arrive only after all three are placed, and the game ends when none of your pieces fits.
Is block puzzle the same as Tetris?
No. In a falling-block game the piece descends while you decide, so speed is part of the skill. A block puzzle has no timer and nothing falls — you place pieces at your own pace, which makes it purely a planning game about managing space.
How do you win at block puzzle?
By protecting space rather than chasing clears. Keep at least one open region big enough to take the largest piece in the set, fill from the edges inward, and close single-cell holes early. Most runs end because a large piece has nowhere to go, not because of a missed clear.
