Opening Brawl Boxes are the main way to get Brawlers and resources for the game.
OBTAINING BRAWL BOXES
Brawl Boxes can be obtained regularly by playing the game and getting Tokens from battles. Once you get 100 tokens you will automatically be rewarded with a 1 Brawl Box that you can open at any time.
Boxes can contain Brawlers (unlocking new ones), Tickets for the special events, Token Doublers, Gems, Power Points and Star Power.
Once you have a level 9 Brawler (current limit) you will no longer receive Power Points for that Brawlers. You will also no longer receive duplicated Brawlers anymore.
With a maxed Brawler at level 9, there is a 1% chance of obtaining the Star Power on a regular Brawl Box. This information has been confirmed by Supercell developer Frank on his Twitter.

The Big Box is awarded by collecting 10 Star Tokens.
The content of this box is similar to 3 Brawl Boxes.
The Mega Box can be purchased on the shop for 80 gems, but it will occasionally be offered on sale for 49 gems. It awards roughly the same thing as 10 Brawl Boxes.
