Upgrading your Clubs raises them to the next level, increasing their special abilities and overall value. To do so, you need coins and Club Cards. 

Each Club has its own Club Card which you can collect, and to see how look up I cannot get the Club I want. How do I unlock a Club?

You can find your Clubs by selecting the Club Bag icon from the main page. Here, you can see how many cards you have collected and how many resources you need to upgrade each Club. 

If you see the “UPGRADE” button by clicking on your Club, that means you have enough Club Cards and coins to upgrade. When you tap it, it shall upgrade immediately, consuming the cards and coins it requires.

If you don't have enough resources to upgrade your Club, you can tap on it to see the number of Coins needed. The number of Cards needed is also displayed on the Club Card.
