Chess vs. Chat

Chess vs. Chat lets Twitch streamers host chess games in which viewers suggest moves by typing them in chat. You can play against your chat or let viewers compete among themselves. The move with the most votes is played when a turn ends.

Set up a match

You set the timer and choose a game mode before starting. You can pause the timer to give viewers more time, or play without a timer and end turns when you choose. Start a regular game or load FEN code from your clipboard to play from a fixed position or try a chess puzzle.

Viewers are sorted into teams, with their names, emotes and votes displayed in the game window. Bits and subscriptions receive additional highlighting. Viewers earn points by participating, and after a game you can view a high score of participants, as well as high scores for the game and across past games.

Chat features

The game can log match activity and includes an optional Twitch Reply bot that lets viewers request information with chat commands:

• !points: Show the points earned.
• !Games: Show the number of games participated in, won and lost.
• !Messages: Show the number of messages sent.
• !Votes: Show the number of votes cast.
• !Side: Show whether the viewer is playing as White or Black.

Chat emotes appear above the viewer who sent them. The game supports default global emotes. You can also limit or throttle incoming messages to reduce visual clutter and game load.

Appearance and records

You can customize each side’s piece sprites, the board’s tile colours and the background colour. The game can be scaled and repositioned in different scenes without restarting. It records each match’s starting position and moves locally on your hard drive, so you can review them later, even when the game is closed.

Twitch moderation

The game uses moderation actions from Twitch chat: banning a viewer removes them from the game, while muting a viewer prevents them from participating. It works as a standalone application and requires Twitch authentication, but no other accounts or authentication. Twitch login uses OAuth, and credentials are encrypted and remembered after the first login. Viewers do not need a separate application or website; they suggest moves directly in Twitch chat.
