About this guide
plaingame.pro is an independent guide to Plain, the daily estimation game. The game lives at playplain.app. This site explains the rules, the score, and the searches that are not that game.
Who operates the game
The terms on playplain.app say Plain is run by Orinoco Invest GmbH. The impressum names Thomas Schweins as the representative, with Düsseldorf commercial register HRB 88182 and VAT DE361342378. The about page says the product is made and run by one person. I keep both: the company is the legal operator, and the about page is describing the size of the team. This guide is not that company, and it is not that person.
Who operates this site
plaingame.pro publishes the pages you are reading. The contact address is [email protected]. The game’s own support inbox, printed on playplain.app/contact, is a different address. Write to us about a wrong number on this guide. Write to them about an account on the game.
Other sites that use the name
plaingame.fun, plaingame.app, playplain.org, and playplain.online are not this guide and are not the official game. Some of them offer modes the official about page does not. Alldle has pointed the Plain entry at plaingame.fun. The game itself is playplain.app. Our editorial policy says how a sentence earns a place here.
