What is Sandtris?
Sandtris is a falling-block puzzle game created by A-Team. Shapes drop from the top of the screen and disintegrate into flowing sand grains the moment they touch the floor or another surface. Instead of clearing solid rows of geometric tiles, your objective is to span the entire playfield from the left border to the right border using a single matching color. The title runs directly in modern web browsers on desktop computers and mobile handsets without requiring downloads or plugin installations.
Key features
- Granular physics: Blocks dissolve upon landing and settle into loose mounds rather than rigid grids.
- Color-based line clears: Form a continuous horizontal layer of one uniform shade across the screen to dissolve the grains.
- Multiple play styles: Tackle a relaxed session in classic mode or test your reflexes in speeding-up mode.
- Cross-device support: Control the action via desktop mouse or mobile touch displays in portrait orientation.
- Instant resets: New rounds load immediately after sand fills the board up to the ceiling.
How to play
- Start a round by choosing classic mode or speeding-up mode.
- Observe the color and silhouette of the piece descending from above.
- Guide the piece horizontally toward your target lane before it touches down.
- Watch the structure crumble into loose particles that slide into lower dips.
- Align matching colors across the entire width of the bin to dissolve the layer.
- Prevent the accumulated sand from piling up to the top threshold.

Sand settling mechanics
Unlike standard block puzzlers where shapes lock into rigid cubic grids, every piece in this game collapses into loose grains of sand upon impact. The grains tumble down slopes and slip into crevices, creating natural dunes across the bottom of the container. Because particles slide toward lower ground, clearing a line demands consistent color distribution rather than merely filling spatial voids. A single strip of matching color spanning from the far left wall to the far right wall triggers a clearance, causing all mounds sitting overhead to cascade downward into the newly opened territory.
Tips and strategy
- Target low valleys: Drop incoming shapes into recessed areas so shifting particles settle evenly across the floor.
- Prioritize matching shades: Group identical hues together so complete horizontal bands can form without unwanted color splits.
- Anticipate lateral flow: Particles tumble sideways off steep peaks, so account for spreading grains when planning your drops.
- Maintain a level base: Preventing tall isolated spires makes it easier to bridge colors from left to right.
- React decisively under speed: When velocity increases, pick a landing spot immediately rather than adjusting back and forth.
Game modes
Classic mode
Classic mode provides a balanced experience where shapes drop at an even tempo. This setting allows you to study the dunes, anticipate how particles will scatter, and plan color connections across the board with measured precision.
Speeding-up mode
Speeding-up mode escalates the challenge by increasing the fall rate over time. As pieces descend with greater velocity, you must make prompt steering decisions before the shapes collapse into the piles below.
