Imagine two Rocket Riches offers sit side by side in 2026: one advertises a 100% match, the other a 200% match. You choose the larger figure, then discover its playthrough target is calculated on a much bigger amount.
That is why a bonus percentage needs context before it can tell you much about value. When checking an offer through Rocket Riches Casino Login, read the terms alongside the headline: the calculation base, eligible games, time limit and withdrawal rules can all change what the number means. The examples below are hypothetical, not a description of a current Rocket Riches promotion; check the offer’s own terms before deciding.
Essential terms behind a casino bonus
A match percentage describes how a bonus relates to a qualifying deposit, usually subject to a maximum. A 100% match on a NZ$100 deposit would add NZ$100, while a 200% match might add NZ$200 if the cap allows it. The percentage alone does not tell you the amount you will receive: the cap and minimum deposit matter too.
Playthrough, also called wagering, is the eligible stake total required before bonus funds or related winnings can be withdrawn. Its calculation base is crucial. “35× bonus” means something different from “20× deposit plus bonus”. In the first case, the multiplier applies to bonus funds; in the second, it applies to the combined amount. Always check the wording rather than assuming a familiar-looking multiplier uses a familiar base.
- Contribution: the share of a stake that counts towards playthrough. A game may contribute fully, partly or not at all.
- Expiry: the period allowed to meet the conditions. Unmet requirements may mean the bonus expires.
- Maximum withdrawal: a limit that may apply to bonus-related winnings, even after playthrough is complete.
- Eligible deposit: the payment method or deposit amount that qualifies for the offer, as defined in its terms.
Practical consequences of comparing the wrong number
A larger match can create a larger playthrough target if the multiplier applies to the deposit and bonus together. Game contribution can add another hurdle: if only part of a slot stake counts, the amount wagered may need to be much higher than the remaining playthrough figure suggests. A short expiry can make an otherwise manageable target difficult to complete at a considered pace.
These details also affect comparisons between offers. Look at the cash you must deposit, the bonus you would actually receive, the total eligible turnover, and any withdrawal cap. Read the rules for eligible games and payment methods as well. If a condition is unclear, do not treat the headline as a substitute for it; seek clarification from the operator before opting in.
A hypothetical Rocket Riches comparison
Suppose a player deposits NZ$100 and sees two fictional offers. Offer A is a 100% match with playthrough of 35× the bonus. Offer B is a 200% match, capped at NZ$200, with playthrough of 20× the deposit plus bonus. Assume both offers accept the deposit and the player receives the full stated bonus.
| Fictional offer | Bonus received | Playthrough calculation | Turnover target |
|---|---|---|---|
| A: 100% match | NZ$100 | 35 × NZ$100 bonus | NZ$3,500 |
| B: 200% match | NZ$200 | 20 × NZ$300 deposit plus bonus | NZ$6,000 |
Offer B has the more impressive percentage and a larger bonus, but its stated turnover target is NZ$2,500 higher under these assumptions. That does not automatically make Offer A better: expiry, game contribution, caps and other conditions could change the practical comparison. The useful question is not “Which percentage is bigger?” but “What must I do, and what restrictions apply, before I can withdraw?”
The exception that can change the result
The comparison shifts if the offers use different calculation bases or qualifying rules. For instance, a promotion with a high match could still have a lower target if its multiplier applies only to the bonus, while another with a smaller match might calculate playthrough on the combined deposit and bonus. A lower contribution rate, excluded game category, or withdrawal limit can reverse the apparent advantage again.
So compare like with like: confirm the bonus amount you would receive, identify the exact playthrough base, then check contribution, expiry and cash-out conditions in the current terms. Treat the headline as an invitation to inspect an offer, not as a measure of its overall value. Set a spending limit before playing, and do not deposit money you cannot afford to lose.
