FrankenSketch is a browser-based party game for 3 to 5 players. Each round one player is the guesser and the rest are artists. All artists receive the same prompt and draw their assigned quarter of a 2x2 picture without seeing the other quarters or what anyone else is drawing. When the time limit expires the four pieces are combined into a single image, which the guesser sees for the first time and then submits one written guess. The guesser never sees the prompt until the guess is locked in. There is no scoring and no win condition, and the guesser role rotates each round. The game runs in a web browser with no download and no account, and the interface and prompts are available in ten languages.
