Block Puzzle

Block Puzzle gives you a 10×10 grid and three shapes at a time. Place them anywhere they fit, and any row or column you fill completely clears away. When none of your remaining shapes fit anywhere on the board, the game is over.

Nothing falls and nothing is timed. This is not a reaction game — it is entirely about space management. Every shape you place makes the board tighter, and the three you are offered next are random, so leaving yourself room for a 3×3 square you have not been dealt yet is a bet you have to make constantly.

Clearing several lines with one placement scores extra, which creates the central tension: setting up a multi-line clear means deliberately filling the board close to the edge of disaster.

1. Three shapes appear in the tray below the board. Tap one to select it, then tap the board to place it.
2. A shape must fit entirely in empty cells. While a shape is selected, a translucent preview shows where it would land — orange if it fits, red if it does not.
3. Complete a full row or column and it clears. You score 1 point per cell placed, plus 10 per line cleared, with a growing bonus for clearing more than one at once.
4. Once all three shapes are used, a new set of three appears. Shapes that cannot fit anywhere on the current board are dimmed.
5. The game ends when none of your remaining shapes fit. Your best score is stored in your browser.

Tap to select, tap to place. Click or tap a shape in the tray — it highlights in orange — then click or tap the cell where you want its top-left corner. Tapping the same shape again deselects it.

On desktop, moving the cursor over the board shows a live preview of the placement before you commit. Placements that would not fit are shown in red and are ignored if you click, so you cannot lose a shape to a misclick.

There are no keyboard controls, no rotation and no timer. Shapes are placed in the orientation shown — not being able to rotate is a deliberate part of the puzzle.

• Keep the middle clear, not the edges. Large shapes need contiguous open space, and the centre is the only place a 3×3 will ever fit once the board fills.
• Place large shapes first. Use the big pieces while there is still room, and save the single cells and 2-blocks for filling awkward gaps at the end of a set.
• Never leave single-cell holes. An isolated empty cell can only be filled by one shape out of eighteen. Two or three of them and the board is effectively dead.
• Work toward near-complete rows. A row with one or two gaps is an opportunity; a row with five is dead weight. Finish what you started.
• Check all three shapes before placing any. The set is committed once you start — placing the small one first often means the big one no longer fits anywhere.
