How to use my Scrabble Go rewards?

Hello
The image rewards accumulate to unlock tiles that will dress up your letters. It’s decoration. You can find the tiles under the S at the top of the app, just before the envelope
Red tickets are tokens that give you access to these rounds in the Arenas. (To play, click on the cup at the bottom)
Blue jewels are wildcards to help you progress further in levels (adventures or puzzles)
I haven't found the purple tickets yet
There you go ???? enjoy the game ????
