The terms behind the headline.
How to read a bonus before deciding whether it makes sense.
AtomicStorm editorialUpdated 2026-09-17Establish the wagering base
A “30×” requirement is incomplete without its base. On a $100 bonus, 30 times the bonus means $3,000 of qualifying wagering. If the same multiplier applies to a $100 deposit plus a $100 bonus, the requirement becomes $6,000.
Check contribution
If a game contributes 20%, $100 wagered advances the qualifying requirement by only $20. A zero-contribution or excluded game does not help clear it.
| Hypothetical requirement | Contribution | Actual wagering to satisfy it |
|---|---|---|
| $3,000 qualifying wagering | 100% | $3,000 |
| $3,000 qualifying wagering | 20% | $15,000 |
These simplified examples assume the contribution rate remains constant and every wager complies with the terms.
Separate a model from a forecast
Multiplying total wagering by a game’s theoretical house edge provides a basic expected-cost illustration. It does not estimate the probability of completing the requirement before funds run out, account for changing stakes, or fully value a promotion.
Read these details together
- Which games are eligible and their contribution rates.
- The maximum wager and any prohibited features or play patterns.
- The expiry time and whether withdrawing forfeits the bonus.
- Any cap on winnings or cashout.
- Whether your location and account qualify.
If the terms are unclear, obtain clarification from the operator before accepting. Only assess strategies that are allowed by the specific promotion. A large advertised bonus does not imply a positive expected return.
