Brawl Stars is a casual mobile moba game by Supercell with 1-3 minute session lengths and a variety of game-modes (3v3, battle royale etc.) that focus less on destroying towers and more on raw PVP with a single objective, such as collecting 10 gems as a team and surviving with them for 15 seconds.

The core gameplay is fun and the art / UI extremely polished, and instead of lootboxes to unlock new characters, we have a battle pass system (the game used to have loot boxes, but these were removed in 2022).

Yes, you can buy iAP to level up your heroes faster, but this doesn't impact the gameplay experience of a free player much, as players who spend money quickly rise to the higher tiers, which means we won't meet them again before our heroes are just as high level.
