Board Game Arena

I noticed that a player can have more than 100% wins in a boardgame. How is it calculated?

If you win against several opponents, it counts as more than 100%. I think it's something like N*50, with N being the total number of players in the game, so that it's 100 when you win a 2-player game, 150 for a 3-player game, 200 for 4 players, etc. I'm not sure how it is for team games. In any case, you have to win the game, being 2nd in a 12-player game still counts as a loss.
