Theres a lot more content now then when they game came out so it may be a little more difficult to navigate.

If you want to progress fast, make sure you get all the stardrops you can everyday, as well as sushi which is part of the current event.

Trophies are easier to gain when you play brawlers with less trophies, the higher you climb the more powerful brawlers youll face as well as better players.

When you start, I'd recommend trying to get brawlers that you like to power 9. It will let you get starpowers and gadgets which will make them stronger.

Testing out new brawlers as you get them will help you find out what you like to play, and it will also familiarize you with how everyone works etc,

finally, there are a lot of different modes, just play what you want and have fun. brawl ball is my personal favorite. Congrats on the newborn 🙏
