Sand Tetris: blocks that fall apart, and lines that are not lines
Sand Tetris looks like the old game for about one second. A coloured shape — a bar, an L, a J, an S, a plus — hangs at the top of a tall well. Then it lands, and instead of locking into a grid it bursts into hundreds of grains that slide off each other and settle into a heap. The well is 94 grains wide and 153 tall, and every grain keeps its colour.
That changes what a "line" is. Nothing clears because a row is full. What clears is a colour: when grains of one colour touch each other in a continuous band from the left wall to the right wall, the band flashes and vanishes, and the sand above it pours down into the gap. A thin, crooked ribbon counts, as long as it is unbroken and the same colour all the way.
The game here is Sandtris by Markus Neuy, subtitled Pixel Tetris — the browser game most people mean when they search for Sand Tetris. It runs from sandtetris.com itself. The old page on this domain framed a copy on GitHub Pages that has since disappeared, so this is the first time in a while that the game on sandtetris.com has actually loaded.
Controls & mechanics
| Action | Control | Purpose |
|---|---|---|
| Slide | Hold Left/Right arrows or A/D | Moves the shape across the top of the well |
| Drop | Down arrow, S or Space | Let go of the key and the shape falls |
| Mouse / touch | Drag the shape, then let go | The shaded column shows where it will land |
| Skip | Skip button | Swaps the current shape for the next one; short cooldown between uses |
| Settings | Esc or the gear | Sound, music and the way back to the menu |
How to score more in Sand Tetris
- Build flat, not tall: Sand spreads sideways as it settles. Drop shapes near the walls first so the floor rises evenly, and keep the middle low.
- Think in colours, not rows: Only one colour can clear a band. Watch the Next box and put each shape where its colour already lies.
- Bridge the last gap: A band that reaches both walls except for one notch only needs a few grains. A small shape dropped exactly there often finishes it.
- Chain clears for double points: Another clear within 15 seconds of the last one scores double. Set up a second band before you finish the first.
- Use Skip on the wrong colour: If the shape would bury a band you are building, skip it and take the next one.
- Watch the red line: The game ends when the heap reaches the red line near the top, not when a column fills. Tall piles in the middle end games fast.
Key features
- Real falling sand: Every shape breaks into loose grains that roll, slide and pile up in a 94 × 153 field.
- Colour-band clears: Join one colour from wall to wall, by any path, and the whole band disappears.
- Two modes: Classic waits for you to drop each shape; Speeding Up drops them for you, faster and faster.
- Combo scoring: Clears within 15 seconds of each other score double, with an x2 pop-up.
- Next and Skip: See the next shape, and skip the current one when its colour does not fit.
- Saved in the browser: Your best score, sound settings and an unfinished game stay in local storage.

Pro tip: In Classic nothing falls until you say so. Before each drop, look at the Next box: if the next shape is the same colour, drop this one on the far side so the two can meet in the middle.
