Drag pieces from a tray of three onto an 8x8 board. Full rows and columns clear, and the game ends when no piece fits. No timer.
What is Block Puzzle 8x8?
Block Puzzle 8x8 is a single-player puzzle in which you place pieces made of square blocks onto an 8x8 grid and clear any row or column you fill completely. Pieces arrive three at a time, they never fall and never rotate, and there is no timer. The game ends when none of the pieces you are holding fits anywhere on the board.
Each turn is a small packing problem: where do these three shapes go so that lines clear and the board stays open for whatever comes next?
How to play Block Puzzle
The tray: below or beside the board is a tray with three pieces. Drag a piece onto the grid and drop it where it fits. It must sit entirely inside the board and cannot overlap blocks already there. You can place the three pieces in any order. When all three are placed, a new set of three appears.
Clearing lines: when a row or a column is completely full, it is cleared. If one placement fills a row and a column at the same time, both clear together, and so do several rows or columns at once. While you drag, the board shows where the piece will land and lights up the lines that will clear.
The pieces: single blocks, straight bars of 2, 3, 4 and 5 blocks in both directions, 2x2 and 3x3 squares, 2x3 slabs, small three-block corners and large five-block corners. Each orientation is a separate piece, so a bar may arrive standing up or lying down, and you have to use it the way it comes.
Game over: after each placement the game checks whether any piece left in the tray fits somewhere. If none does, the game ends with No space left. When a new tray is dealt, the game makes sure at least one of the three pieces can be placed.
Block Puzzle scoring
Every block you place is worth 1 point, so a 3x3 square gives 9. Clearing lines adds a bonus that grows quickly with the number of lines cleared in one placement: one line gives 10, two lines 30, three lines 60 and four lines 100.
There is also a streak. Each placement that clears at least one line right after another clearing placement raises the streak, and the line bonus is multiplied by it. Clearing one line three placements in a row gives 10, then 20, then 30. A placement that clears nothing resets the streak.
Block Puzzle strategy
Keep room for the big pieces. The 3x3 square and the five-block bars are the shapes that end games. Try to keep at least one open 3x3 area and one free lane of five in each direction. If you can no longer fit a 3x3, every tray becomes a risk.
Build from the edges. Filling along the walls and in the corners leaves the middle open, and an open middle accepts almost any piece. Pieces dropped in the centre split the board into awkward pockets.
Avoid single holes. A one-block gap surrounded by filled cells can only be filled by the single-block piece, which does not come often. When you place a piece, look at the cells it leaves next to it.
Plan all three pieces before placing the first. The order matters. Place the piece with the fewest possible spots first, and check that the other two still fit afterwards. A placement that clears a line can also make room for a piece that did not fit before.
Aim for double clears. Because two lines pay three times as much as one, setting up a row and a column that one piece will complete together is worth a little patience. Long bars and the large corners are good finishers for this.
Keep the streak alive when you can, but do not force it. After a clear, a second clearing placement doubles the bonus. When the board is crowded, though, survival comes first: a high streak ends the moment the game does.
Where block puzzles come from
Clearing complete lines is an idea from falling-block games of the 1980s. Grid puzzles where pieces are placed freely and nothing falls spread on mobile phones in the 2010s, usually with a tray of three pieces and both rows and columns clearing. Other variants exist with 10x10 boards, hexagonal grids, rotating pieces or timers. Our version keeps an 8x8 board, three pieces, no rotation and no clock, and our piece set leaves out the four-block T, S, Z, J and L shapes.
