The Tutorial Skip button is on the left instead of the right, where it's intuitive to press on the right side. Don't fall for this or you will be subject to a time sink.

Click on the "Home" Button, then on the Homescreen click on the "Mail" icon on the left. This should open up the mail. Collect all the mail, which should consist of Staminade, and more importantly, 3500 Beads and a 4/5* Ticket.

If you don't have a strong like for any particular character, here's the reroll Tier List from underl1ght, EN World Flipper Discord Mod. To check out their explanations, here is their document.
