This isn't just a number on paper — the bonus is credited directly to your account and can be used across multiple game categories, including slots, live casino, and sports betting.
The bonus calculation is straightforward. Say you deposit MYR 200 as your first deposit — you will receive an additional MYR 300 as a bonus, bringing your total balance to MYR 500 to play with. The more you deposit, the higher the bonus value, up to the maximum cap.
