The slot catalogue runs to more than 500 titles and is led by Games Global, the studio that operated as Microgaming until its rebrand and that built the progressive jackpot networks the platform is known for. Every result is produced by a certified random number generator, independently tested by eCOGRA, and each spin is calculated independently of every spin before it — there is no accumulating state that makes a machine due for anything.

Reel formats and how they differ
Slot categories are distinctions of mechanics rather than of theme, and knowing which mechanic a title uses is more useful than knowing what it is about.
- Classic reelsThree reels and a small number of fixed paylines. Fast rounds, minimal feature layering.Wacky Panda Power Combo
- Video slotsFive reels with bonus rounds, free spin triggers and expanding symbols layered onto the base game.Aurora Wilds, Fiona of Lucksley
- Megaways and variable waysThe number of symbols per reel changes each spin, so the count of winning combinations varies round to round rather than staying fixed.Rainbow Bonanza Power Combo
- Cascade and cluster mechanicsWinning symbols are removed and replaced, allowing consecutive wins from one stake.Shark Pop: Coin Collect
- Progressive jackpotsA portion of every stake feeds a shared prize pool across the network.Mega Moolah, 9 Masks of Fire King Millions
The Mega Moolah and WowPot networks
Progressive jackpots pool a small share of every stake placed on every connected game across every casino running the network. That pooling is why the top prizes reach the figures they do, and it is also why the mechanics differ from an ordinary slot in two ways worth understanding before playing one.
| Title | Network | Notes |
|---|---|---|
| Mega Moolah | Mega Moolah | The original network jackpot and the brand's best-known title |
| Atlantean Treasures: Mega Moolah | Mega Moolah | Four-tier prize structure on the same network |
| Wheel of Wishes | WowPot | Wheel-triggered jackpot round |
| 9 Masks of Fire King Millions | WowPot | Jackpot variant of the 9 Masks of Fire series |
| Thunderstruck Wild Lightning | Games Global progressives | Norse-themed entry in a long-running series |
| 3 Powers of Zeus Power Combo | Games Global progressives | Combination feature build with a progressive layer |
A jackpot win is not capped by the weekly withdrawal ceiling. Standard play is released under a weekly schedule where a balance exceeds the ceiling. Progressive jackpot wins are exempt and paid outside that schedule. This is one of the more favourable terms attached to the account and it is set out in full on the withdrawals page.
The trade-off nobody advertises. The share of each stake that feeds the jackpot pool comes out of the game's base return. A progressive slot therefore returns less on ordinary spins than a comparable non-progressive title, with the difference held in a pool that the overwhelming majority of players never win. Progressive play is entertainment with a lottery-shaped outcome, and it should be approached on that basis rather than as an expected value proposition.
Finding the return-to-player figure on any game
Return to player is a property of an individual game, set by the studio that built it. It is not a property of a casino, and a single percentage presented as a site-wide payout figure is not a meaningful number — a fact worth stating because figures ranging from 89.8% to 97.48% circulate in third-party write-ups about this brand, all of them presented as though they described the platform.
Most slots in this catalogue return between 95.5% and 96% over the long run. The figure for any specific game is published by the studio inside the game itself, and that published figure is the one that applies.
- Open the game and locate the menu or information icon, usually in a corner of the game frame.
- Select Game Info, Help or Paytable depending on how the studio labelled it.
- Scroll to the return-to-player statement, typically at the end of the rules section alongside the maximum win and volatility note.
Two properties of that number matter more than its size. It is a long-run average calculated across many millions of spins, so it describes the mathematical design of the game rather than any session. And it says nothing about the shape of the outcome: two games with identical return figures can produce entirely different session experiences depending on volatility. A high return figure does not make a session more likely to end ahead.
eCOGRA's role is to test that a game performs to its published specification and that the random number generator is genuinely random. That testing verifies the figure is honest; it does not make the figure a forecast. How the audit chain works is covered on the games page.
Volatility and session length
Volatility describes how a game distributes its returns, and it is the property that most affects what a session actually feels like at a given budget.
| Volatility | What it produces | Bankroll implication |
|---|---|---|
| Low | Frequent small returns, shallow swings | A given budget lasts longer; large outcomes are rare |
| Medium | A mix of small returns and occasional larger ones | Moderate swings in both directions |
| High | Long stretches without a return, punctuated by rare large hits | The same budget depletes faster and less evenly; a larger reserve is needed to reach a feature |
Volatility does not change expected value. Two games at 96% return the same proportion over the long run whether one is low volatility and the other high — they simply arrange it differently. Choosing volatility is choosing a session shape, not improving odds. Anyone told otherwise is being sold a system that does not exist.
A five-point check before the first spin
- Open the paytable and confirm how the bonus round is triggered — several titles require a specific symbol count that is not obvious from the reels.
- Note the published return figure in the game info panel.
- Check the volatility note, where the studio provides one, against the intended session length.
- Set the stake from the session budget rather than the other way round — dividing an intended budget by an intended number of spins gives the stake.
- Decide on autoplay deliberately. It runs spins faster than manual play, which means the same budget is consumed in less time.
Where a bonus is active, a maximum bet rule applies for the duration of the wagering and exceeding it voids the bonus. The cap is in the promotion terms on the promotions page, and it should be checked before the stake is set rather than after.
Demo mode and what it does not show
Useful for
Learning how a bonus round triggers and resolves before committing real money to a game with complex features. Understanding the pace of a mechanic. Confirming that a title is worth a real-money session at all.
Does not show
The experience of real stakes, which is materially different. And demo results carry no predictive value whatsoever: a strong run in demo mode says nothing about a real-money session, because every spin in either mode is independently generated.
Studios behind the catalogue
- Games Global (formerly Microgaming)
- Apricot
- Pragmatic Play
- On Air Entertainment
- Evolution (live)
Games Global supplies the bulk of the slot catalogue and both progressive networks. Players searching under the Microgaming name are searching for the same studio: the rebrand changed the company name, not the games or the jackpot networks.
