Getting your game ready…
0 placements · 0 lines cleared
Tap a piece, then its top-left square. Or drag it: the preview shows where it will land, raised above your finger on touch screens. No rotation, no timer.
Keyboard, saving & undo
Choose a piece with 1, 2 or 3. Arrow keys move the top-left square; Enter or Space places it. Escape cancels your selection. Tab moves between the board and controls.
Your board, pieces, score and best are saved after a placement, Undo or a confirmed new game. Undo restores one placement in this tab, including a clear or a refilled tray; it is not kept after reload. Best scores never decrease when you undo. Storage failures leave your draft in this tab.
THREE SHAPES. ONE OPEN GRID.
How to play Block Puzzle
Place whole shapes on empty squares of the 8×8 board. Keep making space and aim for your own best score. There is no target score or countdown.
- Choose from all three. Use the offered pieces in any order. They cannot rotate or overlap filled squares. A piece with no room now may fit after another piece clears a line.
- Finish a row or column. Every full horizontal row and vertical column clears together after each placement. Diagonals and 3×3 boxes do not clear on their own.
- Make room for the next tray. Three new pieces arrive only after all three slots are used. After each placement and refill, the game ends if no remaining piece fits anywhere. Undo can take back the last placement.
ONE SQUARE, TWO LINES
A small example you can follow
These original, read-only diagrams use a prepared board. Reading them does not change your current game.
Back to your current game ↑1. Find the shared gap
The bottom row and right column each need the same square. All other squares in those two lines are filled.
2. Place one square
A single-square piece fills that gap. The bottom row and right column are now both full.
3. Clear both lines together
Both lines clear at once. This placement earns 1 point for the square plus 20 for two lines: 21 points. The shared square disappears once.
KNOW WHAT EACH MOVE EARNS
Simple, visible scoring
Each newly placed square scores 1 point. Each row or column completed by that placement scores 10 more. A five-square piece clearing two lines earns 5 + 20 = 25 points.
- One rule throughout. No streak multiplier, combo multiplier or extra empty-board bonus. Preview shows a legal placement’s points before you confirm it.
- Room matters more than rushing. Look at all three shapes. Keep some connected empty space for a long line or a 3×3 square; isolated holes can be hard to use.
- Try one step again. Undo returns the last placement, its score and any cleared lines or refilled tray. Your best score stays. One step is available in this tab; reloading clears Undo.
A LITTLE SPACE TO EXPERIMENT
Before your next piece.
Is this the same as sliding blocks or Sudoku blocks?
No. Here you add shapes to empty squares, then clear full rows and columns. You do not slide pieces already on the board. This is an 8×8 classic game; filling a 3×3 box does not clear it, unlike some 9×9 Sudoku-style block games. For a sliding puzzle, try Unblock Car.
How are new pieces chosen?
The game chooses from 31 fixed shape orientations, including lines, squares, corners, T shapes and zigzags. Each orientation is equally likely in the pseudo-random generator; repeats are possible. Pieces are not adapted to your board or score. The next tray is not guaranteed to fit, and the game does not promise an endlessly playable sequence. Restoring a game keeps its current pieces and generator state.
Why did a piece stay in the tray?
A piece must fit completely inside the board without covering a filled square. A rejected drop costs no points or turn. If one piece has no room, try another: a clear can create space. The game ends only when none of the remaining pieces fits anywhere.
Can I save or share my game?
Placements, Undo and a confirmed new game save this game and your best score in the current browser when storage is available. There is no account, cloud sync, public leaderboard or game-sharing link for this version. Best scores are local records, not verified competition results. Clearing browser data removes them.

Where do these shapes and rules come from?
This is Brainfold’s implementation of classic placement-and-line-clearing rules, using generic geometric shapes and original diagrams. We do not copy another game’s artwork, boards, scoring system or code. You can compare the row-and-column format at Wood Block Puzzle and the additional 3×3-box rule at Easybrain’s Blockudoku.
