CB666CWelcome Bonuses: Working Out What the Offer Is Worth
Who: Written by Tanvir Rahman, who analyses promotional structures. How: Each structure below is costed against a 97% RTP game with slots contributing 100%. Why: A welcome bonus is the first financial decision a new player makes and it is usually made on the headline percentage alone.
A 100% welcome bonus is worth taking if wagering is 30x or less on the bonus alone. At a 3% house edge, clearing ৳1,000 at 30x costs about ৳900 in expectation — leaving ৳100 of value. At 40x it costs ৳1,200 and you are ৳200 down before variance.
A welcome bonus is presented as free money and functions as a turnover contract. The match percentage in the headline is the least important number in the offer.
This page works through the four terms that decide whether a welcome offer is worth accepting, in the order they matter.
Term one: the wagering multiplier
| Match | Deposit | Bonus | Wagering | Expected cost | Net value |
|---|---|---|---|---|---|
| 100% | ৳1,000 | ৳1,000 | 20x | ৳600 | +৳400 |
| 100% | ৳1,000 | ৳1,000 | 30x | ৳900 | +৳100 |
| 100% | ৳1,000 | ৳1,000 | 35x | ৳1,050 | −৳50 |
| 200% | ৳1,000 | ৳2,000 | 40x | ৳2,400 | −৳400 |
Term two: the wagering base
| Structure | ৳1,000 + ৳1,000 at 30x | Turnover | Expected cost |
|---|---|---|---|
| Bonus only | 30 × ৳1,000 | ৳30,000 | ৳900 |
| Deposit + bonus | 30 × ৳2,000 | ৳60,000 | ৳1,800 |
Term three: game contribution
| Your preferred game | Contribution | Effective wagering on a 30x offer |
|---|---|---|
| Slots | 100% | 30x |
| Crash games | 50% | 60x |
| Live blackjack | 10% | 300x |
| Excluded title | 0% | Never clears |
If you intend to play live tables, a welcome bonus is almost certainly not for you. The arithmetic does not survive a 10% contribution rate.
Term four: maximum win and maximum bet
- Max win: commonly 5–20x the bonus. Below 10x is poor.
- Max bet while clearing: commonly ৳200–৳500 per round.
- Breach consequence: bonus and associated winnings voided.
- Bonus buys: usually count as a single very large bet and can trigger a breach.
Working a real example end to end
- Bonus received: ৳2,000.
- Required turnover: 30 × ৳2,000 = ৳60,000.
- Expected cost at 3%: ৳1,800.
- Net expected value: ৳2,000 − ৳1,800 = +৳200.
- Rounds needed at ৳50: 1,200, or about 86 per day over 14 days.
- Maximum withdrawable from bonus funds: ৳20,000.
When to decline outright
- Wagering above 33x on the bonus alone.
- Any deposit-plus-bonus wagering base.
- Maximum win cap below 10x the bonus.
- Expiry requiring more play per day than you would normally do.
- Your preferred games contributing under 50%.
The first-deposit exception
A bonus locks the balance behind wagering before you know whether the operator pays. Welcome offers are almost always available on a later deposit.
- First deposit: minimum, no bonus, play briefly, withdraw, time it.
- If the payout is clean, deposit again and take the bonus then.
- If it is not, you have lost the minimum rather than a cleared bonus.

A bonus extends a session past the point you would otherwise have stopped. That is its commercial purpose, and it is worth naming. Decide your session budget independently of any bonus balance, and treat bonus funds as already spent.
If an offer is making you deposit more than you planned, decline it. Deposit limits in account settings apply immediately when lowered; self-exclusion applies within 24 hours across all access points.
