Playing it on stream or in a video

Solo: press Play and you face a bot instantly. A full round takes about a minute, so it works as a quick break between games.
Vs a friend or mod: press "or challenge a friend" to get a private link. Send it to them, and the round starts when they open it.
With chat: let chat suggest what to write, then see if their prompt beats the bot. The reveal (both pictures and scores counting up) is the clip moment.
Family-friendly targets, and it works in 18 languages.
