BlameChat is a browser-based interactive collection of multiplayer party games played in a shared room. One player hosts and puts a room code on screen; everyone else joins from a phone, tablet, or computer browser. No download or account is required to play. Most games set the host against everyone else, with the room's move decided by majority vote — the host plays the board while the room votes its reply. Others are played between all participants. Supported player counts range from 2 to 100 depending on the game. Games include board games such as Chess, Checkers, Connect Four and Battleships; word and guessing games such as Hangman and Spectrum; and social games such as Cards vs Room, Jury Duty and Burn or Bot.
