There are four different modes available in brawl stars mod apk as mentioned below:
a) Bounty Mode: In bounty mode, there will be two enemy teams containing three members each, and the common goal of both groups is to kill as many enemies as possible but beware of getting killed because once you die, you will not be able to play again and your points will only go on increasing as long as you can stay alive.
b) Smash & Grab Mode: In this mode, there are two familiar teams named "Heist" and "Smash and grab". Each unit has its unique role like Heist Team contains one boss (Brawler with high health as compared to other players) plus two brawlers while the second team includes three members, including a Brawler having a medium amount of health, so it's a tug-of-war between both teams where winning team gets ten crystals.
c) Showdown: There will be ten players in this game, and all ten have access to powers and weapons to fight for crystals from the centre of the map, which is at stake here. The best player will get the main prize and the rest of the other players will get nothing.
d) Robo Rumble: In this mode, a team containing three members has to battle against hordes of robots controlled by evil forces who simply want to eliminate all brawlers. All three team members have access to powers and weapons where they will fight it out until time expires or until one member emerges as the winner with winning numbers of kills in their kitty.
