Rotatris is a web puzzle game where the board rotates

Rotatris is a puzzle game where the board turns when a block lands. If a piece falls to the right, the board rotates right. If it falls to the left, the board rotates left. If it lands in the center, the board stays still.

The idea started from a spinning-board concept by Freya Holmér, but the block-clearing rules were newly designed. The game now has three modes. Avalanche clears blocks when the player fills a target shape in the center, then gives a new puzzle shape. Layers works like a circular version of Tetris, where pieces clear after forming complete rings around the middle.

Orbital is similar to Avalanche, but lets the player manually spin the board. The animations are still being improved, and the game is playable at rotatris.com.
