What Are Wagering Requirements?
Wagering requirements (also called playthrough requirements or rollover) are conditions attached to casino bonuses that specify how many times you must bet the bonus amount before you can withdraw any winnings.
For example, if you receive a NZ$100 bonus with 30x wagering requirements, you must place a total of NZ$3,000 in bets (100 x 30) before you can withdraw any winnings derived from that bonus.
How to Calculate Real Cost
Understanding the real cost of wagering requirements requires knowing the RTP of the games you play. If you play a slot with 96% RTP and have NZ$3,000 in wagering to complete, you can expect to lose approximately NZ$120 (4% of NZ$3,000).
This means your NZ$100 bonus with 30x wagering has an expected value of roughly -NZ$20. At higher wagering requirements like 50x or 60x, the expected value becomes significantly more negative.
Game Contribution Percentages
Not all games contribute equally to wagering requirements. Most casinos use a weighted contribution system where slots count 100%, but table games contribute significantly less. A typical breakdown: Slots 100%, Video Poker 10%, Roulette 10%, Blackjack 5%.
This means if you are playing blackjack to clear a NZ$3,000 wagering requirement at 5% contribution, you would actually need to bet NZ$60,000 in total. Always check the game contribution table.
Red Flags in Bonus Terms
Watch out for these warning signs: wagering requirements above 50x (industry average is 30-35x), maximum bet limits during wagering (usually NZ$5-10 per spin), very short expiry periods (7 days or less), and low maximum withdrawal caps.
Some casinos also have a vaguely worded "bonus abuse" clause that can be used to void winnings at the operator's discretion. If the terms seem designed to make it impossible to withdraw, consider it a red flag.
Tips for Clearing Wagering Requirements
Choose high-RTP slots (96%+) with 100% contribution to minimise your expected loss during wagering. Avoid high-volatility games as they increase the risk of busting your balance before completing the requirements.
Consider whether a bonus is actually worth claiming. A smaller bonus with lower wagering (e.g., NZ$50 at 20x) often provides better expected value than a large bonus with high wagering (e.g., NZ$500 at 60x). Sometimes the best strategy is to skip the bonus entirely.
