Sandtris — Play Free Online

Sandtris takes the falling-block idea you know from Tetris and replaces the solid pieces with sand. Each shape that drops from the top is made of thousands of tiny coloured grains, and the moment it lands it crumbles, spreads out and settles into the pile like a real heap of sand. That one change turns a familiar puzzle into something much more fluid and unpredictable.

The goal is not to fill a row. Instead you clear sand by joining grains of the same colour into a continuous band that stretches from the left wall to the right wall. When such a band forms, it burns away and everything above it sinks down. A session is a steady loop of placing a piece, watching the sand flow, and deciding whether the colours underneath are lining up for a clear.

If you came to Doodle Jump for quick, one-more-try arcade sessions, this is a calmer cousin. There is no jumping and no timer racing you; the pressure comes from the pile creeping toward the top. It runs in the browser with nothing to install, and it suits a few minutes at a desk or on a phone.

How to play

Use the arrow keys or WASD to move the falling piece sideways and speed it up, and the mouse to aim and select where the menus ask for it. On a phone, tap and swipe instead. Steer the piece before it lands, because once the grains hit the pile you can no longer change where they end up.

A round ends when the sand piles up to the top of the well. Watch the colour of the next piece, not just the current one, so you can plan which colour should sit where.

Tips

• Build wide, flat layers of a single colour rather than tall stacks. A band only counts when it touches both walls, so height in the middle does nothing for you.
• Drop a piece against a wall to anchor one end of a future band, then work across toward the other side.
• Avoid sprinkling a different colour into a layer you are building; a few stray grains of the wrong colour can break the connection.
• Do not rush the drop. Because sand spreads after landing, a slower placement lets you see where it will settle.
