Run the official TETR.IO server?
Discord marks TETR.IO as a verified server, which it gives to the official servers of games, studios, products and organisations. This part of the page is for the team behind it.
The GroupFinds bot is free for TETR.IO
Full analytics history, celebration cards when members hit milestones, weekly recaps of the most active members, levelling, automation and live server numbers you can embed on your own site. All of it is free, with no card and no verification step: the bot starts counting the moment it joins. Proving with Discord that you own the server is what opens its settings dashboard here, so that nobody else can change them.
