Hi Stijn VanEven, thank you for your quick answer !
For the step 1), yes that is what I want to achieve
For the step 2), "the amount of times a player won that game" will always be 1 so it does not fit exactly my need. BUT it gave me another idea. In your example, is it possible to select "Game 1" and "Game 2" and see which players have won both of them ?
The perfect thing would be what I asked first
