Build your collection of Beys. For a first session in Bey Rivals, get familiar with what you already have before focusing on what to collect next. Read the information the game gives you instead of judging a spinning top by its appearance alone.
Make your Bey your own. Customization is part of Bey Rivals, so treat your setup as something to understand as well as something to change. Compare the descriptions you can see in the game, and make one adjustment at a time when experimenting.
Take your spinning top into the arena. Bey Rivals includes opponents controlled by players and NPCs. Pay attention to how a fight unfolds: what you tried, how your opponent responded, and what you would like to do differently in the next battle.
Keep developing your Bey through training, upgrades and new abilities. Progression in Bey Rivals is a reason to return to a familiar setup and learn more about it. An upgrade and a better understanding of your options are different kinds of progress.
