What is Block Blast?
Block Blast is a block puzzle game played on an 8×8 board. You get three blocks at a time, place them on empty squares, and any row or column you fill clears away. The game ends when none of the blocks you hold will fit.
The version on this page is Block Blast Puzzle, a free web game hosted by BlockBlast100, a fan site. The Block Blast! mobile app is made by Hungry Studio, and its rules and scoring may differ from what we describe here.
New to the game? The rules and steps below are enough to start. If you already play, the scoring table shows what this version paid in our test games.
| Board | 8×8 squares |
|---|---|
| Blocks | 3 at a time; a new set comes when all three are placed |
| Rotation | None |
| Timer | None |
| Clearing a line | Fill all 8 squares of a row or column |
| Game over | None of your remaining blocks fits |
| Cost | Free, no download, no account |
| Saving | Best score and unfinished game stay in your browser |
It plays a little like Tetris without gravity. Nothing falls, so you pick the spot for every block and can think for as long as you like.
How to play Block Blast
Drag the three blocks onto the board one at a time and complete rows or columns before you run out of room.
- Press Play at the top of the page. The game loads in the same box. On a first visit, a short tutorial shows a hand dragging the first block into place.
- Drag a block from the tray below the board and drop it on empty squares. While you drag, the block floats a little above your finger or cursor so you can see where it will land.
- Fill a row or a column. As soon as all eight squares in a line are full, the line clears and those squares are free again.
- Place all three blocks to get the next three. If one block has no room, place the others first. The game only ends when none of your blocks can go anywhere.
How scoring and combos work
Every square you place is worth 1 point, and every line you clear earns a bonus. When you clear lines on move after move, you build a combo, and each clear in a combo pays 10 more points per line than the one before.
We tested this version on October 28, 2026. A script dragged the blocks in a Chromium browser, and we read the score from a screenshot after every move of a 37-move game. In two more full games, which ended at 1,073 and 1,530 points, the placement and the two-row clear we checked gave the same numbers. These are the numbers from the 37-move log:
| Move | Points |
|---|---|
| Placing a block | 1 per square (a 3×3 block gives 9) |
| 1st clear in a combo | 20 per line |
| 2nd clear | 30 per line |
| 3rd clear | 40 per line |
| Each clear after that | 10 more per line each time (110 per line on the 10th clear, the highest in our log) |
A combo doesn't end the first time you miss. In our log of one game, it lasted through three placements with no clear and ended after four. The board shows the current step as "Combo x3", "Combo x5" and so on.
The two pictures below show one move. A 2×2 block finished two rows on the third clear of a combo, so it scored 4 points for its squares plus 80 for the lines (40 each).
Tips for a higher Block Blast score
Combos are where the big points are: the first clear of a combo pays 20 per line, and the tenth clear in our log paid 110 per line. A combo only survives while you have room to keep clearing, so most of these tips are about keeping the board open.
- Keep a 3×3 space open. The 3×3 square and the five- and six-square bars need the most room. In the game pictured below, half the board was empty, but no 3×3 space was left.
- Check all three blocks before you place the first one, so the last one still has a spot.
- Clear a line every few moves. Each clear in a combo pays more than the last, and the combo ends after a few moves without one.
- Build from the edges and corners in. Blocks dropped in the middle split the open space into pieces that big blocks can't use.
- Avoid leaving single empty squares between blocks. Only the one-square block can fill them.
- Use the time. There is no clock, so look over the whole board before each move.
Playing on a phone, PC or Chromebook
Block Blast runs in a web browser with WebGL turned on, so there is no app to install. We tested it in Chromium on a computer and with Chromium's phone emulation, including touch dragging. We haven't tried it yet on a real iPhone, Android phone, tablet or Chromebook.
On a computer you drag blocks with the mouse. If your browser supports it, a Full screen button appears at the top right of the game for a bigger board. On a touch screen you drag with your finger, and on a narrow screen such as a phone the game fills the full width.
The game files are about 10 MB, so the first load can take a while on a slow connection. If it stalls, check your connection and press Try again. If the page says WebGL is off, try another browser or turn on hardware acceleration in your browser settings.

Block Blast FAQ
Is Block Blast free to play online?
Yes. Block Blast is free to play on this page, with nothing to buy and no account to create.
Do I need to download anything?
You don't install anything. Your browser loads about 10 MB of game files when you press Play, and the game runs inside the page.
