Two Key Terms to Know Before Claiming a Bonus

Rollover (Turnover)

Definition: The total amount you must wager before the bonus value can be withdrawn as cash. Rollover is calculated based on the bonus value, not the main balance.
Simple example: If you receive a Rp100.000 bonus with a 5x rollover requirement, you need to place a total of Rp500.000 in bets before you can withdraw the bonus winnings.

Bonus Validity Period

Definition: The timeframe in which a bonus must be claimed and used before it expires. Once the deadline passes, the bonus is automatically removed from your account.
Simple example: A cashback bonus claimed on Monday may be valid for up to seven days. If the rollover is not completed within that period, the remaining bonus will be deactivated.

Get to Know the Bonus Types on This Platform

First Deposit Bonus

Designed for new bossmahjong members making their first deposit. The bonus is calculated as a percentage of the deposit amount — for example, a deposit of Rp200.000 may qualify for an additional bonus at a percentage set by the current active terms. Be sure to read the rollover requirements before claiming.

Weekly Cashback and Rebate

Active players who place bets throughout the week are eligible for cashback based on their net losses during that period. Rebates are typically processed every Monday and credited directly to the account balance with no additional rollover requirement — subject to the platform's current active terms.

Bonuses for Sports and Esports Betting

Football: 1 League and International Tournaments

Users in Surabaya who regularly follow Persebaya and place bets on the Indonesian 1 League often use deposit bonuses to increase the value of their initial wagers. Bossmahjong provides both domestic and international football betting markets — from the AFC Asian Cup to Italian Serie A matches — so bonuses can be used across categories in accordance with the terms and conditions.

Esports: MLBB, Free Fire, and Valorant

The esports community in Bandung and Yogyakarta that actively follows Mobile Legends Bang Bang and Valorant tournaments can use sports betting bonuses for esports categories. Make sure to check whether esports bet types count toward the rollover calculation for the current active bonus — some bonuses limit rollover contribution per game category.

IDR Deposit to Activate Bonuses: A Step-by-Step Guide

Deposit Steps to Claim a Bonus

Log in to your bossmahjong account and open the Cashier menu.
Select a payment method: GoPay, OVO, BCA bank transfer, or DANA.
Enter the deposit amount (e.g., Rp150.000) that meets the minimum requirement for the active bonus.
Once the deposit is confirmed, go to the Promotions page and click "Claim" on the desired bonus.
The bonus is credited to your promotional balance — start betting to meet the rollover requirement.

Withdrawal Steps After Completing the Rollover

Check the rollover status in your account panel — make sure it is 100% fulfilled.
Open the Cashier menu and select "Withdraw".
Enter the amount and destination account, then confirm the request.
Processing typically takes 1–24 hours depending on the method and verification queue.

Method	Estimated Processing Time	Min. Deposit (example)
GoPay	1–10 minutes	Rp50.000
OVO	1–10 minutes	Rp50.000
BCA Bank Transfer	5–60 minutes	Rp100.000

User in Medan: Claiming a Bonus After Work Hours

A user in Medan often accesses bossmahjong in the evening after work. They make a deposit via GoPay for Rp100.000, then immediately claim the active deposit bonus from the Promotions page. The claiming process takes just a few clicks and the bonus appears in their promotional balance within minutes.

User in Semarang: Cashback for Sports Betting

Another user from Semarang who regularly bets on Persija Jakarta and Borneo FC matches takes advantage of the weekly cashback. Every Monday morning, he checks the cashier panel to see whether the cashback has been credited. The rebate is applied without any additional rollover requirements, so he can withdraw it immediately or use it for his next bets.

What's Often Overlooked: Important Notes on Bonuses

One active bonus at a time. Most platforms only allow one bonus to run at a time. Claiming a new bonus before the previous one is completed can void the rollover progress already made. Check your active bonus status in the account panel before claiming a new promotion at bossmahjong.

Rollover contributions differ by category. Bets on certain slots may contribute fully (100%) toward the rollover, while sports bets with low odds may only contribute partially. Always read the rollover contribution details on the bonus description page before placing bets.

Not all bonuses are eligible for direct withdrawal. Some bonuses can only be used for betting (non-cashable), meaning the bonus itself cannot be withdrawn — only winnings from bets placed using that bonus can be cashed out once the rollover is met.

Checklist Before Claiming Any Bonus

Read the rollover terms in full — note how many times the bonus value must be wagered and within how many days.

Check the bonus validity period — note the expiry date so you don't miss the deadline before completing the rollover.

Make sure no other bonus is currently active — claiming two bonuses simultaneously can void one of them.

Check the rollover contribution per game category — slots, live casino, and sports betting typically have different contribution percentages.

Confirm the minimum deposit required to activate the bonus — deposits below the minimum will not trigger the bonus even if the promotion is active.

Verify that your account is fully verified — unverified accounts may not be able to claim or cash out bonuses.

Live Casino and Slots: Rollover Contributions You Should Know

Slots: Highest Rollover Contribution

Online slots generally contribute 100% toward the bonus rollover requirement. This means every Rp10.000 you wager on slot machines counts in full toward the rollover. This makes slots a popular choice among users who want to complete their rollover faster.

Live Casino: Baccarat and Roulette

Live casino games such as Baccarat and Roulette may only contribute partially (for example, 10–30%) toward the bonus rollover, depending on the specific promotion terms. Users in Jakarta who prefer live casino games need to wager more to complete the rollover compared to users who choose slots.

Frequently Asked Questions About Bonus Rules

Log in to your account, make a deposit that meets the minimum amount required by the promotion, then go to the Promotions page and click the Claim button on the available bonus. The bonus will be credited automatically to your promotional balance once the deposit is confirmed.

No. Rollover requirements typically have a validity period of 7–30 days depending on the bonus type. During that period, you can place bets gradually until the rollover is met. If the deadline passes, the bonus and any winnings that have not met the rollover will be forfeited.

Most sports bonuses can be used for esports betting, including Mobile Legends and Free Fire. However, the rollover contribution for the esports category may differ from regular football betting. Check the bonus details on the promotions page for confirmation.

Submitting a withdrawal before the rollover is met will generally void the active bonus and remove the remaining promotional balance. Only the main balance (not derived from a bonus) can be withdrawn under these circumstances. Make sure the rollover is 100% before withdrawing funds.

Generally no. Platforms only allow one bonus to run at a time per account. You need to complete or cancel your currently active bonus before you can claim a new promotion. Exceptions may apply to certain bonus types such as automatic weekly rebates.

Most local payment methods — including GoPay, OVO, DANA, and bank transfers — can be used for deposits that qualify for a bonus. However, certain promotions may restrict which payment methods are eligible. Always check the promotion terms before depositing to confirm your method qualifies.
