## What is Otheris?

A fresh take on board games combining Reversi’s “sandwich and flip” mechanics with tetromino-based strategy. Rotate and place the given pieces each turn to trap and flip your opponent’s color in one move. Enjoy both the satisfying chain reversals and deep tactical play in short matches. Perfect for local multiplayer on a single device.

• Rules
If you sandwich your opponent’s color in any row of the placed piece, all pieces in between are flipped to your color.
If no moves are available, your turn is skipped.
The game ends when the board is filled or neither player can make a move.

• Features
Control the board with shapes: a new fusion of Tetromino × Reversi strategy
Simple controls with satisfying flip effects
Quick matches for short play sessions
Local multiplayer and bot matches
