Wagering Contribution for Slot Play
Megaways-style slots with expanding reels are grouped under the Slots category in our library, and every category counts differently toward the 40x default wagering requirement on a casino bonus. Buy Feature spins, the format many expanding-reel titles use to let a player pay directly into a bonus round, are tracked separately from standard spins because they clear wagering at a different rate.
| Category | Wagering Contribution |
|---|---|
| Slots | 100% |
| Buy Feature | 50% |
| Instant Win | 5% |
| Scratch | 0% |
| Table Games | 0% |
| Live Games | 0% |
A standard spin on an expanding-reel slot clears wagering at the full rate, while triggering a paid bonus buy on the same title only clears it at half speed, so mixing the two changes how quickly a 40x target is met.
The Mechanic Behind Expanding-Reel Slots
Megaways-style mechanics change the number of symbols on each reel at the start of every spin, which changes the total number of ways to win from one spin to the next. This sits alongside the games we host, where titles are organised into categories such as Slots, Buy Feature slots, Jackpot games and Instant win.
How It Plays Out Round to Round
Because reel height resets each spin, a round can open with a short set of ways to win and close on a much longer one before the result settles — the server-side RNG decides the outcome, and that server result is what prevails over anything shown on screen for every game except live casino. Buy Feature slots let a player pay to jump straight into a bonus round rather than spin for it, which is why our wagering table tracks Buy Feature separately from ordinary Slots spins.
Our slot suppliers include NetEnt, Microgaming, Amatic, NYX, BGaming and Pragmatic Play, covering the mix of expanding-reel and buy-feature formats in the library. Game availability can vary by provider and territory, so the current title list in the casino section is the accurate reference at any given time.
Playing Megaways-Style Slots With a Bonus
When a casino bonus is active, spins on expanding-reel slots are capped at a £5 maximum bet while wagering is in progress, a limit that also covers gamble features and in-game bonus buys. The default wagering requirement is 40x the bonus amount, and winnings generated from a bonus are capped at 10x the bonus value once wagering is cleared.
Deposit bonuses follow a sticky structure: real money is played first and the bonus itself is held back until the wagering target is met, so an expanding-reel session funded by a bonus won't unlock a cashout until the full 40x is cleared. Full terms, including how the wagering requirements apply per game category, sit alongside the bonus list in the Wallet & Bonuses area of the account.
Anyone who wants to see how an expanding-reel round behaves before committing a deposit can do so in demo mode, and newly added slots appear in the casino section once they go live. Game availability in demo mode mirrors what's live there, so testing a title first reflects what can be played for real afterward.
Questions About Megaways-Style Slots
What makes a Megaways slot different from a standard slot?

Do Megaways-style spins count fully toward Ninewin's wagering requirement?
Yes, spins in the Slots category count 100% toward the 40x default wagering requirement on a casino bonus, while Buy Feature spins on the same type of title count at 50%.
Is there a bet limit on expanding-reel slots while wagering a bonus?
Bets are capped at £5 per spin while a casino bonus is being wagered, a limit that also applies to gamble/double-up features and in-game bonus buys.
