Two offers, same casino. One gives you 200 free spins. The other gives you a 100% deposit match up to $200. Which is worth more?
The answer depends on numbers most players never see — spin value, game RTP, and how each is wagered. Here’s how to work it out.
What free spins are actually worth
A free spin has a fixed stake value set by the casino, usually $0.10 or $0.20. Two hundred spins at $0.10 is $20 of stake — not $200 of value, which is how the offer is often perceived.
The expected return is that stake multiplied by the game’s RTP:
What 200 free spins is worth
Before wagering requirements, 200 free spins is worth roughly $19. A headline of “200 FREE SPINS” is doing a lot of work for $19 of expected value.
What a deposit match is worth
A 100% match on a $200 deposit gives you $200 in bonus funds. But you only realise that value if you clear the wagering requirement, and clearing it costs you house edge along the way.
What a $200 match at 30x is worth
At 30x, that bonus has negative expected value. The turnover required costs more in house edge than the bonus is worth.
The break-even multiplier
There’s a simple threshold. A bonus breaks even when:
Wagering multiplier × house edge = 1
At a 4% house edge (96% RTP), break-even is 25x. Below that, the bonus has positive expected value. Above it, negative.
| Game RTP | House edge | Break-even wagering |
|---|---|---|
| 98% | 2% | 50x |
| 97% | 3% | 33x |
| 96% | 4% | 25x |
| 95% | 5% | 20x |
| 94% | 6% | 16x |
This is why the game you clear on matters as much as the multiplier. A 30x bonus cleared on a 97% RTP slot is roughly break-even. The same bonus on a 94% slot is clearly negative.
So which wins?
It depends on the wagering attached to each.
Free spins win when winnings carry low or no wagering. Some operators pay spin winnings as cash. That $19 expected value is then real, and it cost you nothing.
Deposit matches win when the multiplier sits below break-even for the games you play, and the cap is high enough to matter. A 100% match at 20x on decent slots beats 200 spins comfortably.
Neither wins when spins carry 40x wagering on winnings — a common structure that quietly removes most of the value.
Check the wagering on free spin winnings, not just the spins. “200 free spins, 40x on winnings” is a very different offer from “200 free spins, winnings paid as cash.”
A worked comparison
| Offer A | Offer B | |
|---|---|---|
| Type | 200 free spins | 100% up to $200 |
| Wagering | None — cash winnings | 30x bonus |
| Gross value | $19.20 | $200 |
| Cost of turnover | $0 | $240 |
| Net expected value | +$19.20 | −$40 |
The smaller-sounding offer is worth more. That’s the entire point of doing the maths.
Every offer lists its wagering multiplier
So you can apply the break-even test before you deposit, not after.
What to check before claiming either
- Free spins: value per spin, which game, wagering on winnings, any cap on winnings
- Deposit match: multiplier, whether it applies to bonus or bonus+deposit, game weighting, max bet, expiry
- Both: max cashout, excluded games, minimum deposit to qualify
The honest framing
Positive expected value on a bonus doesn’t mean you’ll profit. It means you’re losing slightly less than you would playing without one. Variance still dominates any single session, and the house edge still applies to every spin.
The right use of this maths is choosing the better of two offers and avoiding the ones that are worse than nothing — not building a strategy around clearing bonuses for income. That strategy doesn’t exist.
