What is SANDTRIS and what can you do on sandtris.com?

SANDTRIS is a free browser-based falling-block puzzle game at sandtris.com, made by Franco Miranda with p5.js and inspired by MSLIVO's SETRIS. You can play it directly in the browser, submit a score to a weekly leaderboard, and share the game. The twist: instead of clearing rows by filling them with any blocks, you clear lines by connecting blocks of the same color across the screen. The site explicitly states it is not affiliated with Tetris®.

How the game works

The core mechanic differs from standard Tetris. Each block has a color, and a line clears when the same color connects across the screen. That means placement decisions are driven by color matching as much as by fit, so you'll often pass up a tidy stack to keep same-colored pieces adjacent.

The page credits the concept as inspired by SETRIS by MSLIVO, and notes the game was built with p5.js.

Who it's for

SANDTRIS suits players who want a short, no-install puzzle session in a browser and who enjoy a color-matching twist on falling-block games. If you're looking for classic Tetris rules, the color-connection requirement will feel different — and the site makes clear it isn't a Tetris product. The page doesn't list pricing or account requirements, so check the site itself if you need to confirm access details before playing.
