Zetris

Zetris — A Fresh Twist on the Classic Falling Block Puzzle

What if Tetris pieces were made of triangles instead of squares?

That's the simple but brilliant idea behind Zetris. Instead of the familiar square-based tetrominos you know from classic puzzle games, Zetris uses pieces built entirely from triangles. Two triangles placed together form a complete square — and your goal is to arrange falling pieces to create complete rows and clear the board.

It sounds familiar. It feels completely new.

How to Play

Shapes made of triangles fall from above. Push them left or right, rotate them, and guide them into position. When a complete row of squares fills the board, it disappears and everything above drops down — just like you'd expect. But the triangle mechanics create entirely new challenges, new strategies, and new satisfying moments that classic Tetris never could.

Every few pieces, a single loose triangle falls. This special piece can pass through other shapes and settle into the gaps between them — plugging holes that would otherwise be impossible to fill. Master the gap filler and your scores will skyrocket.
