Othello
Flip the script (and the pieces). Start with Bella's playful randomness, challenge Coop's solid strategy, then face Bentley's calculated dominance. Trap your opponent, flip their pieces, and dominate the board. Warning: Bentley shows no mercy and will crush your dreams.
Play
Three dogs, one engine at three depths. Your pick is remembered across the arcade.
