How to play Block Puzzle
Three pieces sit beside an 8×8 board. Choose a piece, then tap or click the square where its top-left corner should go. Its whole shape must fit on empty squares. You can also drag a piece from the tray onto the board; the preview shows where it will land. On a touchscreen the dragged shape sits above your finger. Tapping is an alternative if dragging is awkward.
Fill all eight squares in a horizontal row or a vertical column to clear that line and make space. A placement can finish several lines at once, including a row and column that cross. Those lines clear together. Block colours distinguish the shapes; matching colours is not part of the rules.
Use the three pieces in any order. A fresh set arrives only when all three have been placed. Pieces keep their orientation: there is no rotation, falling-block timer or countdown. The round ends when none of the pieces still in the tray fits anywhere. A piece marked “No space yet” may become playable after another piece clears a line.
Controls and placement previews
- Tap or click: choose a piece, then an empty board square. The square is the top-left corner of the piece's shape.
- Drag: move a piece from its tray over the board, then release. Releasing outside the board or cancelling the gesture does not place it.
- Keyboard: press 1, 2 or 3 to choose a tray piece and focus the board. Use arrow keys to move the position, then Enter or Space to place. Tab reaches the tray and action buttons. Held placement keys do not keep placing pieces.
A mint preview marks a legal placement; a dashed pink outline marks a position that will not fit. Complete lines turn amber in the preview. Trying an occupied square or an edge where the shape would spill off does not cost points or use the piece. Sound is optional and follows the site sound setting. Reduced-motion preferences remove the short line-clear animation.
Scoring, undo and stickers
Each placed square earns one point. Clearing lines adds ten times the number of simultaneous lines squared: one line adds 10 bonus points, two add 40 and three add 90. A four-square piece completing two lines therefore earns 44 points. Best is the highest score saved on this device; Lines counts completed rows and columns in the current round.
Undo move takes back the most recent placement, including any line clears. It restores the previous pieces and the state of the next deal, rather than rolling new pieces. Undo is one step deep. Your best score and already earned stickers stay.
The shared sticker book rewards 1, 5, 15, 30 and 75 lines cleared in one round: First Line, Space Maker, Good Planner, Line Builder and Clear Thinker. Stickers are awarded when a placement clears a line. Opening the page, choosing pieces and undoing a move do not earn them.
Return to your saved board
The game saves after accepted placements, undo and a new round when browser storage is available. Returning to this page restores the board, score, remaining pieces and available undo. There is no motion to pause. New round asks before replacing a round you have played; you can choose Keep this round instead.
These saves belong to this browser, not an account. Clearing site data removes the round and local best. If saving fails, a message explains that the board is only held in the tab and offers Save this board to retry. If another tab changes the saved round, this tab keeps its current board and asks before replacing the other save.
Make room for the next three pieces
Look at all three shapes before placing the first. Keep a longer stretch of empty squares for bars and a wider space for square pieces. A tempting single-line clear can leave a narrow gap that no remaining piece can fill. Try preparing a row and column together, but keep enough room to finish the current tray: you cannot discard a piece to request another set.
