Key Terms to Know Before Claiming Your Bonus

Get familiar with these terms so you know what to expect when using the welcome bonus.

Rollover / Wagering Requirements

The rollover is the minimum amount you need to wager using your bonus value before it can be withdrawn. Example: a 5x rollover on a RM100 bonus means you need to place RM500 worth of bets before withdrawing the bonus funds.

Contribution Rate

Not all game types contribute equally to the rollover. Sports Betting may count at 100%, while certain games may only contribute 10% or 50%. Check the terms for the full list.

Bonus Validity Period

The validity period is the window you have to complete the rollover. If the bonus goes unused or the rollover isn't completed within this period, the bonus will expire automatically and cannot be recovered.

Identity Verification (KYC)

KYC is an identity verification process that requires you to submit a valid ID document. This is needed to secure your account and ensure withdrawals go through without issues.

Bonus Balance vs. Cash Balance

Your account may show two balances: cash balance (real money withdrawable at any time) and bonus balance (subject to rollover conditions). Be sure you understand the difference between the two.

Minimum Odds for Rollover

Some platforms require minimum odds for bets to count towards rollover. Bets placed with odds below the threshold may not be counted. Check bonus terms for minimum odds values.
