How to use
- Pick a block from the tray
The tray holds three random blocks: tap to select (or keys 1/2/3) and the chosen block highlights. Once all three are placed, a fresh batch appears automatically.
- Drop it on the board
Tap a target cell and the block lands with its top-left corner there (arrow keys move a cursor, Enter drops). Ghost highlights show exactly where it will sit.
- Fill rows and columns to clear
A complete row or column clears for points. There is no gravity, and cells stay exactly where you put them, so planning is everything.
- Multiply with multi-clears
Clearing k lines with one placement awards 10×k²: two lines score 40, three score 90. Simultaneous clears are the real score engine.
- No space, no game
The run ends when none of the remaining tray blocks fits anywhere. Your best score is stored locally in the browser.
About this tool
Block Blast is one of the most popular puzzle games of recent years: it fuses Tetris-style line clears with free-form tangram placement. There is no falling pressure and no timer. Because every placement is permanent, the 8x8 board still fills with tension, and three 5-cell bars can turn luxury space into a crisis instantly.
This version ships 17 classic shapes in a random tray, row-and-column multi-clear multipliers, cursor keyboard play and a local best score. It is forgiving for beginners: no penalties, and you can restart whenever you like. It is demanding for veterans, because high scores require preparing the board two or three placements ahead.
One formula drives every tactic here. A placement that clears k lines at once pays 10 times k squared: one line is 10 points, two lines 40, three lines 90. That square curve is why banking a multi-clear beats firing single clears the moment you see them. The tray holds exactly three pieces and refills only when all three are placed, so every decision bundles three shapes. Seventeen shapes span from a single cell to the 3x3 square, with T, S and L outlines in the mix.
How it works
The gap in the scoring comes from the square term. Three separate single clears pay 10 each for a total of 30, while one triple clear pays 90. The triple also saves three placements worth of time and risk. With no gravity, every placed cell is permanent, and the only remedy for a bad layout is completing that exact row or column. Keeping a large open region is therefore not tidiness for its own sake. It gives some future placement the chance to complete two lines in a single move.
A fixed tray of three turns single-block decisions into batch decisions. Before placing anything, ask whether the hardest piece in the tray has a home. If the 3x3, the five-bar or the wide L has none, clear space for it first. The 17 shapes range from short bars to the big square, and their familiarity is no accident. Each is placeable alone, yet any three together can sabotage each other. That tension between individual feasibility and batch conflict is where the difficulty, and the planning, lives.
The missing gravity deserves its own attention. Cleared lines never settle or shift, so holes above a clear keep their exact shape. A line is completed by precise placement only, never by patient waiting. The board offers 64 cells and the largest piece covers 9. One triple clear erases up to 24 of them in a stroke, the biggest single rescue available. Tray refills are fully random with no preview of the next batch. Planning runs on the current three shapes and the board, which is why open space beats greedy points. Your best score sits under the local key t55k6-block-blast, with cleared lines counted separately.
When to use it
- A calm pre-sleep wind-down
No falling stack, no timer and no pressure: the pace is entirely yours. Place a few blocks, clear a few lines, and let thinking narrow gently, a kinder final screen than any feed.
- Pocket tangram on the move
Tap-to-place suits one hand, and a cursor mode covers keyboards and tablets. Batches of three are sliced naturally by station intervals, so a run pauses and resumes without losing the thread.
- Planning as a workout
Where this piece fits depends on what the next batch might bring, the essence of forward thinking. A few sessions in, the instinct to prepare two moves ahead becomes noticeably automatic.
- Banking the square bonus
Two simultaneous lines pay 40 and three pay 90, so spend one round counting that difference. Skip two single clears, hold the lines, and clear both with one placement. The habit of waiting forms after a few rounds.
Tips & tricks
- Handle the big pieces first (3x3, 5-bars): the longer you delay them, the more likely they become homeless.
- Keep at least one fully open row or column as an emergency release valve.
- Read the tray before clearing: one double clear beats two singles by a wide score margin.
- Corner placements are the safest home for the 3x3: they flatten two edges at once and never leave an interior hole.
Things to watch
- Postponing the big pieces
The placeable area for a 3x3 or a five-bar shrinks brutally as the board tightens. Playing small pieces first is how big ones end up homeless, so home the largest piece of every batch first.
- Leaving single-cell holes
An isolated gap can only be filled by specific shapes, and one or two holes can retire an entire row. Before placing, check for orphans, because a smaller score now beats an unfixable line later.
- Missing the multi-clear
Two lines one cell from completion, left sitting, get gnawed apart by random shapes. When two lines are nearly full, detour if necessary and deliver a piece that completes both in one placement.
- Clearing without a follow-up
A satisfying clear means little if the two tray pieces left behind have nowhere to go. Before each placement, check where the remaining two shapes could land, and sacrifice a small clear to keep that door open.
