A bonus is a loan against your turnover. The terms describe the interest.
Four numbers, not one
| Figure | What it means | What to watch for |
|---|---|---|
| Headline percentage | How much bonus credit you receive | The number used to advertise, and the least binding |
| Wagering multiple | Turnover needed before withdrawal | Applied to bonus only, or deposit plus bonus — a large difference |
| Game weighting | How much each stake counts toward the requirement | Some titles count at a fraction, or not at all |
| Withdrawal cap | The most you can take out from bonus play | A low cap can make a large bonus worth less than a small one |
If any of the four is missing from the terms page, that is itself the answer.
Worked example: a 300% bonus of ฿3,000 at 25x on deposit plus bonus means ฿100,000 of turnover, with a withdrawal cap that may sit at ฿5000. A 50% bonus of ฿500 at 10x on bonus only means ฿5000 of turnover. The second offer is smaller and better.
When to decline a bonus
Declining is a real option and is often the right one, particularly on a first deposit with an operator you have not tested.
Without a bonus, your balance is yours: you can play a little, request a withdrawal, and find out whether the operator actually pays before committing more. With a bonus, the balance is locked behind a turnover requirement, and you learn nothing about the payout process until you have already put several thousand baht through the client.
Testing the withdrawal first is worth more than any welcome offer.
