Block Blaster: make room before the next shape
Block Blaster is Onki Games’ drag-and-drop block puzzle on an 8×8 board. Place the offered shapes in empty cells and complete a row or column to remove it. Shapes keep their original orientation, so a useful opening must fit the piece you actually have.

- 8×8 placement board
- Shapes cannot rotate
How to play
Think about the whole group of available pieces before committing your first placement. Clearing a line is valuable when it leaves useful space for the next shape.
- 1
Inspect the shapes
Compare the widest piece with the open areas of the board. If only one position fits it, placing a smaller piece there first could leave you stuck.
- 2
Fill a complete line
Drag a piece into empty cells and release it. A fully occupied horizontal row or vertical column clears; leaving even one empty cell prevents that line from disappearing.
- 3
Check the remaining room
After a clear, look again at the shapes still waiting. Use the newly opened cells to continue rather than assuming that every clear produces enough room.
Controls
Desktop controls
- Hold the left mouse button on a shape, drag it over the board, and release to place it.
- There is no rotation control: judge each offered shape in the orientation shown.
Phone and tablet
- Drag a shape with your finger where the game accepts touch input.
- Keep the complete board visible so you can check the footprint before letting go.
What makes this puzzle different
A compact placement problem
The 8×8 layout makes a single misplaced block matter. Useful spaces depend on their shape, not only on the number of empty cells.
Fixed orientation
A long piece cannot be turned to fit a vertical gap. Plan around the piece’s actual width and height instead of an imagined rotated version.
Practical placement tips
- Reserve a connected open area for bulky shapes; scattered single cells offer much less flexibility.
- Check both the row and column crossing a proposed placement. One move may complete intersecting lines and reopen a larger area.
- When two placements clear the same line, prefer the one that leaves fewer enclosed holes and more possible positions for the remaining pieces.
Who might enjoy it
Spatial puzzle fans
This suits players who enjoy comparing shapes and choosing a placement before making a move.
Players practising deliberate moves
The useful habit here is checking the consequences of a placement, especially when a large fixed shape is waiting.
Score, goals and the end of a round
Your practical aim is to keep legal placements available while completing lines and increasing the in-game score. In the usual board puzzle, a run ends when the offered pieces can no longer be placed. If you choose an adventure mode, follow its displayed objective rather than assuming the score alone completes a stage.
Game questions answered
Can you rotate blocks in Block Blaster?+
No. The published rules say the shapes cannot rotate. Keep their displayed orientation in mind when preserving an opening.
Why did my row not clear?+
A row must be completely occupied. Check for an empty cell hidden beside an irregular shape; a nearly complete line still takes up space.
Is this the ball-shooting game called Block Blaster?+
No. This page is the Onki Games grid puzzle. You place shapes on an 8×8 board instead of firing balls at bricks.
What should I do when a large piece will not fit?+
Look for a line you can clear with another offered piece without filling the large piece’s only possible landing area. If no placement opens a suitable space, the run may be blocked.

Try an orderly opening
Start by keeping one useful open area, then watch how your first row clear changes the board.
