Rules
Here are the rules to follow.
It is played from memory
Looking the answer up mid-game empties the game of its point. For you, and for whoever is across from you.
There is nothing to win
No money, no prize, no reward. The leaderboard is worth nothing outside this site.
Any suspicion of cheating means a permanent ban
No warning, no second chance. The account is closed and its ranking removed.
Leaving a game mid-way loses it
Your opponent waits a while, then takes the win. A dropped connection leaves you time to come back.
The data comes from Liquipedia
So a mistake can slip through. The "Report a problem" button, bottom right, lands straight in my inbox.
Each game's rules
This page covers conduct. The rules for Possession, Find the Player and Played For are written on each game's page.
