Stay on this page. When a slot opens you get one minute to take it, then it passes to the next person.
Waiting costs no play time — you only spend it while you are actually in the game.
To play, type this in goxmeor's Twitch chat:
No sign-in, no permissions, no password. The code proves this browser is yours; the chat message proves the Twitch account is. Only type a code this page gave you — a code from anyone else logs them in as you.
Keep twitch.tv/goxmeor open in another tab. Channel points only accrue on Twitch's own page, never through an embed — and channel points are what buy play time.
