Key Doublers

You can buy key doublers from the shop to increase the amount of Keys earned while playing. This booster costs 50 Gems and doubles the next 1,000 Coins received at the end of any match. Key Doublers can also be found occasionally in Brawl Boxes.


Keys can only be used to buy Brawl Boxes, which cost 100 Keys each. This means they are used to obtain Coins, new Brawlers, Tickets, and Power Points.
