As you play more games in the Altador Cup, your Rank will go up. Playing Yooyuball will gain you the most points, followed by Slushie Slinger. Finally Make some Noise and Shootout Showdown will earn you the least points.
The table also shows how many games you should have played to achieve this rank. Of course you can also use a combination of these games. You do not have to have 50 Yooyuball wins to be level 1, you can also have 49 Yooyuball wins, 5 Make some Noise games and 2 Slushie Slinger games (see the calculator for combinations)
