Coins are an in-game currency that can obtained from Brawl Boxes, the Trophy Road, Brawl Pass tiers, the Shop (for Gems), and occasionally for free in the Daily Deals section. Coins are used to either buy Daily Deals from the Shop or to upgrade Brawlers. Occasionally, they can also be used to buy Gadgets, Star Powers, and the True Silver and True Gold Skins for certain Brawlers in the Shop.
Coins can be used to buy Power Points for your Brawlers from the Shop's Daily Deals. The conversion rate for buying Power Points is 2 Coins per Power Point. Gadgets and Star Powers can also be bought from the Shop when the player has a Brawler who is level 7 and 9 respectively. Likewise, Gadgets and Star Powers cost 1000 and 2000 Coins respectively each.
The main use of Coins is to upgrade Brawlers. Once you have enough Power Points, you can spend Coins to advance your Brawler to the next level, up to level 9. To get a Brawler to level 10, you do not need to use Coins or buy Power Points. Instead, you must obtain at least 1 of the Brawler's Star Powers. Once a Brawler has all of their possible Power Points, the Power Points you would get out of a box are converted into Coins.
Coins can be bought in the Shop with Gems. Buying larger Coin packs gives a better value per Gem.
True Skins are exclusive skins available for purchase with Coins. They come in two varieties, True Gold and True Silver skins, with the latter needed to be bought beforehand to buy the former option. These skins will periodically show up in the skin section of the Shop once the Brawlers they are for are at least Power Level 9. Currently, all True Silver skins cost 10,000 Coins, and all True Gold skins cost 25,000 Coins.
Coin Shower Event
Once a month or on certain occasions, there is a Coin Shower event. During the event, a Coin is awarded for every Token earned. A Token Doubler in use is applied before the Coin bonus, resulting in a net gain of 2x Coins. The event does not apply to Quest rewards.
