Booster is like a superpower you can unlock using your Bonus Cash. We are currently offering 4 boosters: 2x Multiplier, 3x Multiplier, 4x Multiplier and 5x Multiplier. You can apply this on any team in the applicable contest and it will multiply your winnings.
For example, if you apply a 3x Multiplier on a team and it wins Rs. 100, we will give you 3 x Rs. 100 = Rs. 300.
All the boosters come with a cap on the max payout, which can be seen on the contest detail screen.
