Megaways turns every spin into a different grid, since the number of symbols on each reel can change round to round. That mechanic sits alongside our 4,000+ casino games, all settled by Random Number Generator results.
Browse 4,000+ GamesMegaways is a slot mechanic where the number of symbols landing on each reel changes with every spin, so the number of ways to win shifts from one spin to the next rather than staying fixed. At Slimking Casino this sits within our wider slot library, where every result is settled by a Random Number Generator rather than a fixed reel layout.
When reels expand, winning symbol clusters are typically cleared and replaced through a cascade, letting one spin trigger several wins in a row before the round ends, often building a multiplier along the way. Multiplier values that build during a cascade reset at the start of the next spin, which keeps each round independent of the last. Our game outcomes rule states plainly that the game server's result prevails over whatever is shown on screen, which is the same principle that governs any expanding-reel spin here.
We describe our supply of over 4,000 casino games, including live dealers, as coming from the biggest software providers in the industry, with NetEnt named among them specifically. Expanding-reel mechanics like this one fall within the slots category of that library, alongside jackpot slots and other formats. Live dealer games and table and card games sit in separate categories, so the ways-to-win format described here is specific to the slot side of that 4,000+ total. That distinction matters when comparing two titles with very different reel heights. Players can browse the full range through slot games, where mechanics, volatility and notable titles are organised by type, or test a title's reel behaviour first in free-play demo mode before wagering real funds.
Before spinning an expanding-reel title, it helps to know how results are generated, how many games sit around it, and who builds the library it belongs to. Reading these details first means a player entering an expanding-reel title already knows that the version they see on screen is not the final word on the result. The figures below come straight from how our casino section is organised, independent of which specific mechanic a title uses.
| Aspect | Detail |
|---|---|
| Game outcomes | Determined by a Random Number Generator; the server result prevails over the screen display |
| Total games | 4,000+ casino games, including live dealers |
| Providers | Described as the biggest software providers in the industry; NetEnt named explicitly |
| Slot categories | Slots and jackpot slots, among other categories in the library |
| Tournaments | Online and in-house tournaments; top positions earn Coins |
These figures apply across the entire slot catalogue, expanding-reel titles included, and the same Random Number Generator rule settles every spin no matter how many ways to win are active that round. This applies whether the title in front of a player uses a single multiplier or several stacked ones.
Slot wagering for bonus funds counts at 100% toward wagering requirements, except for titles on our excluded list, which matters for expanding-reel games since every spin funded from a bonus balance moves a deposit bonus's wagering requirement forward at the full rate. The maximum bet allowed while a casino bonus is active is £5 per spin, a limit that applies no matter how many ways to win a title offers that round.
Our jackpot slots sit outside bonus play entirely, so any pooled-jackpot title with a changing reel count has to be played with a real-money balance rather than bonus funds. This separation also means a session built around pooled jackpots behaves differently from one spent on a standard slot funded by bonus credit. Across the wider casino section, every result — jackpot or otherwise — is generated by the Random Number Generator, and the server's result is what pays out even if the display briefly shows something else. That is true across every provider named within our wider software mix.
Coins are earned for every £100 wagered on casino games, and top finishers in our in-house tournaments also collect Coins that can be exchanged through the Store. Spinning expanding-reel slots during regular play contributes toward both of these the same way any other slot spin does, since Coin accrual isn't tied to a specific mechanic. Weekly Challenges in the casino section work the same way, crediting a fixed amount of Coins per challenge regardless of which reel format is in play.
