I've been looking for a formula to find the "best player" of a certain boardgame. Let me give an example:

Game name: X (3 player game)

player A has won 9 out of 10

player B has won 90 out of 100

player C has won 49 out of 50

player D has won 5 out of 5

...

You can see that the winning % of A and B is equal both that doesn't mean that they are equally good in the game does it? Since my guess is that if someone wins a game 90 out of 100 he is better then someone that wins 9 out of 10? I think that the number of players also might have an impact, since a 2 player game gives a 50% chance of winning and a 3 player game a 33.3% chance...

Anyway the point is I'm trying to come up with a formula that calculates this and gives me the "best" player, and the worst

Is it even possible to calculate this on people with an unequal number of games played?

...

A formula for the "best" player in a game, with each player having played a different amount of games...
