In Brawl Stars, players battle against other players or AI opponents in multiple game modes. Players can choose between different Brawlers, which are divided among 5 rarities (Rare, Super Rare, Epic, Mythic, Legendary). Brawlers can be unlocked through the Starr Road, the Brawl Pass, the Trophy Road, or purchased through the Shop to use in battles.In December 2022, a new progressive unlock system called the "Starr Road" replaced Boxes as the method to unlock Brawlers.The cost to unlock each Brawler on the Starr Road depends on its rarity.

During a match, players can use their Brawler's normal attack or their Super, a special attack that, charges up when damaging an opponent, or in some cases through additional means. Players can also equip their Brawlers with power-ups known as Gadgets, Star Powers, Gears, and Hypercharges; Gadgets and Hypercharges can be activated during a match, while Star Powers and Gears are passive abilities.

In addition, it is possible to purchase skins with Gems, Bling, and Coins, or unlock them through the Brawl Pass or randomly in Starr Drops, which will alter the appearance, animations, effects, and/or sounds of Brawlers. Unlocking a new skin will also give the player a custom emote (if the rarity is above Rare) based off the skin they unlocked
