Where the advertised value goes
Four terms decide what you actually walk away with.
The slot’s RTP. Free spins are tied to one game, and every spin pays back less than it stakes on average. At 96% RTP, $10 of spins returns about $9.60 in winnings. On an 88% slot it’s $8.80, and the wagering eats your balance three times faster.
Wagering on your winnings. This is the one that does the damage. Win $9.60 with a 35x wagering requirement attached and you have to bet $336 before the money is yours. Every bet pays the house edge, so most balances are gone long before you get there.
Game weighting. If slots only count 20% towards the wagering requirement, that $336 turns into $1,680 of real bets. It’s usually buried near the bottom of the terms.
Max cashout. A $20 cap doesn’t change how often you win. It just means the one run that finally pays gets cut down to $20.
The same 50 spins under different terms
All figures are for 50 spins at $0.20 on a medium volatility 96% RTP slot, so a face value of $10. Real value is shown as a share of that face value, so it reads the same whatever currency you play in.
| Offer terms | Real value | Chance of cashing out anything |
|---|
| Winnings paid as cash, no wagering | 96% | 100% |
| 5x wagering | 78% | 70% |
| 10x wagering | 66% | 48% |
| 20x wagering | 52% | 29% |
| 35x wagering | 38% | 18% |
| 35x wagering, max cashout at 2x face value | 28% | 18% |
| 35x wagering, slots count 20% | 7% | 2% |
| 35x wagering on an 88% RTP slot | 3% | 2% |
No-wagering spins are worth about three times a 35x offer of the same size, which is why “no wagering” is the best term you can find in a spins promo. And a low RTP slot with heavy wagering is barely worth claiming: at 88% with 35x attached, 98 players in 100 finish with nothing.
The average is not what you should expect
The average value of a 35x offer works out at 38% of face value, but the typical player gets zero. Both are true. Around 18 in 100 players cash something out, now and then a few hundred, and the other 82 lose the balance clearing the wagering. That small group carries the entire average.
Use the two numbers for different jobs. Real value tells you whether a type of offer is worth claiming over a year of claiming them. The cash-out chance tells you what one attempt will probably feel like.
When free spins are worth claiming
- No wagering, or winnings paid as cash. You keep nearly the full face value. Claim these.
- Wagering of 10x or less on winnings. Still holds most of its value.
- 96% RTP or better, with game weighting at 100% on slots. These two terms decide whether the wagering requirement is survivable at all.
- No max cashout, or a cap well clear of the face value. A cap sitting near the face value removes the only outcome worth playing for.
Anything at 35x or more on a sub-95% slot is entertainment, not value. Claim it because you fancy the spins, not because you expect to cash out.
Every offer in our list of free spins bonuses shows its wagering, weighting and cashout terms, so you can run the ones you’re considering through the calculator above before you claim.
How this calculator works
The calculator runs the offer 4,000 times. Each run plays the spins, then plays any winnings through the wagering bet by bet until the wagering requirement is cleared or the money runs out. It reports the average, the median and how often a run cashes out.
The slot is a model rather than a copy of a real game: a hit rate set by the volatility setting, with payouts scaled to the RTP. Two slots with the same RTP can still play very differently. So use it to compare offers, not to predict how your own spins will go. Nudge an input and the numbers move a percent or two, which is the simulation doing its job.
