Wheels are decorations that you can acquire using special cards, which you can obtain through the special chests. As you acquire cards from the chests, you will unlock different designs that you can equip to improve the aesthetics of the wheel in your games.
If you like to collect objects, you cannot miss the wheels! You will simply have to play games to get chests; each chest will give you different cards that will be useful to unlock new wheels.
Also, now you can get new wheels playing Pick-A-Prize and Trivia Pass.
Entering the “Wheels” section, from the fourth icon on the bottom bar of the main screen, you will find the available wheels, those that you have already obtained and the progress of the special cards that you still need. There you will also have the possibility to press on the one you want to use and select "Equip".
