Big Time Gaming titles occupy a small fraction of this vast portfolio, but you can still choose from 50+ BTG flagships, deep cuts, and more recent games.
Megaways, Megapays, and Megapots slots are among the more popular games developed by this studio that you can play at Casumo. Bonanza Megapays (and Megaways), Millionaire Megapots, Max 2 Megaways, Royal Mint Megaways, and Rasputin Megaways are all bonus-packed, yet beginner-friendly enough for first-time spinners to jump into.
Virtually all Big Time Gaming slots are playable with Casmo’s newcomer’s bonus – a 100% bonus match of up to £50. You’ll need to deposit at least £20 and stake your bonus money a minimum of 10 times to make your winnings withdrawable.
On the banking side, Casumo Casino offers same-day payouts with ultra-low limits of just one pound via Apple Pay, PayPal, Trustly, and Skrill. Online banking and debit cards are also suitable for withdrawals, but are slightly slower.

Midnite
A highly respected online bookmaker, horse race betting, and online casino platform established in 2015 by Dribble Media Ltd., Midnite caters to the diverse needs of British gamblers and slot spinners. Its gaming collection features well over 2,600 titles, over 30 of which are sourced from Big Time Gaming.
Similar to Casumo, Midnite onboarded BTG’s heaviest hitters first, including slots like Millionaire Mystery Box, Danger High Voltage, Sanctuary, Bonanza Falls, Gold Gemaways, and the famous Holdy Diver Megaways: Reel Adventure.
Dozens of other studios keep Midnite’s slot library stocked with exciting jackpots, Drops & Wins, instant win titles, blackjack games, roulette, and many other gaming options. Some of the most prominent developers Midnite is also collaborating with include Nolimit City, ELK, Aristocrat, Hacksaw Gaming, Light & Wonder, and many others.
Newly registered players are offered 100 bonus spins for Pragmatic Play’s Big Bass Splash after depositing and wagering at least £20. However, you can also explore other gambling verticals with alternative sign-up bonuses – punters are offered £30 in free bets, while horse race bettors can grab complimentary plays worth £20 after staking just £10.
Midnite’s Casino Club offers an easy route to free spins; bet £20 to grab 10 bonus plays, stake £100 to unlock 30 FS, and claim 60 free plays when you wager £200. The best thing about this loyalty programme is that you can keep claiming up to 100 spins each week.

Hundreds of games from other studios that use BTG’s proprietary Megaways system are also available, including slots like Cash ‘N Riches Megaways by Games Global, Blueprint Gaming’s Fishin’ Frenzy Megaways, Inspired Gaming’s Reel King Megaways, and Pragmatic’s Extra Juicy Megaways.
One of the main draws of PaddyPower, however, is its exemplary collection of jackpot games, mainly powered by Blueprint, Red Tiger, NetEnt, Playtech, and Core Gaming.

Top Big Time Gaming Games: RTP and Volatility Analysis
Big Time Gaming slots have above-average RTPs, but they can’t compete with ultra-high RTP slots made by certain studios, such as NetEnt. In terms of variance, BTG games cover a broad spectrum, from low-mid to high volatility.
More importantly, the RTPs of BTG-made games don’t vary too drastically – there are no games with super-low return-to-player scores (e.g. 92-94%), but at the same time, the developer hasn’t produced dozens of games with RTPs of 97% and up.
| Game Title | Game Type | RTP % | Volatility | Unique Mechanic |
|---|---|---|---|---|
| Queen of Riches | Megaways slot | 96.90% | High | Stacked Wild Reels, Reel Clone |
| Monopoly Deluxe | Megaways slot | 96.84% | High | Bonus Monopoly Reel |
| Castle of Terror | Video slot | 96.72% | Medium | Holy Water Wild Transform, 2 types of Bonus Games |
Queen of Riches
Queen of Riches is a Megaways video slot packed with up to 117,649 dynamically selected paylines. It’s an older slot made in 2016, but it stands out from the provider’s catalogue with an impressive RTP of 96.90%, a superb maximum win limit of 77,800x, and a wide range of bonus features.
The base game is played on a 6×7 grid – an oversized field that lends itself to the main bonuses like Stacked Wilds and Cloned Reels. The former is represented by the Cleopatra Wild symbol, which may appear to cover an entire reel to help you string together better winning combinations.
Reel Clone is a randomly triggered feature that can hit on any spin, creating between 2 and 6 completely identical reels. Best of all, Reel Clone can also clone Stacked Wilds, although Cleopatra will never visit the first reel.
One of the few downsides of this game is the lack of a Bonus Round. There are no Scatters or FS symbols, meaning that you can only use cash or bonus money to spin the reels.
Monopoly Deluxe
You don’t need to be an avid fan of Monopoly as a board game to enjoy this slot, but it certainly helps memorise the rules. Monopoly Deluxe is essentially a two-part Megaways game; the base game is played on a standard grid-style field, while the second revolves around the bonus reel modeled after the Monopoly board.
Mr. Monopoly, the sharp-dressed gentleman below the main field, will move along the bonus reel whenever you spin. Special bonuses, win multipliers, or in-game modifiers may apply depending on where he lands.
On the base field, every win triggers a Cascade, where winning symbols are replaced with new ones. With each tumbling sequence, Mr. Monopoly will move again. If he lands on a Property with Houses (Green) or Hotels (Red), you’ll receive a win multiplier derived from the number of properties. When Mr. Monopoly lands on the Go symbol, all Megaways lines (117,649) will automatically activate, filling all reels with the maximum number of symbols.
The Community Chest will send Mr. Monopoly to a random property, while Chance cards may trigger one of three in-game modifiers – activate Max Megaways (same as landing on Go), send Mr. Monopoly to a property (Community Chest), or give you 12 free spins. If you happen to draw 12 bonus plays from Chance and land 3 scatters, you’ll receive free games twice.
When the bonus round begins, Train Stations and Utility Properties (e.g. Water Works) may randomly be unlocked on any play. Stations give you +1 FS, while Utility cards increase the global multiplier by +1.
Castle of Terror
Castle of Terror is a spooky video slot with a bit simpler bonuses than Monopoly Deluxe. Its RTP is quite high at 96.72%, and its medium variance makes it a bit more suited for playing with bonus money.
On every spin, a random number of Character symbols (Vampire, Lady, Gardener, or Maid) can be splashed with Holy Water, transforming them into Wilds and increasing their win multipliers by +1.
Two types of scatters can land during the base game. Drawing at least 3 Regular Scatters gives you 12 free games, +3 more for every additional scatter, while the appearance of at least one Gold Megascatter awards enhanced Free Spins.
Your free games will always start with a guaranteed Holy Water hit, and your global win multiplier won’t reset between plays. Take note of the Blood Drop icons at the flanks of the playing field, as every time the global multiplier reaches a multiple of 20 (e.g., 20x, 40x, 60x, and so on), you’ll be awarded 6 more free spins.
Enhanced Free Spins improve Holy Water multipliers by +2 rather than +1, and your starting multiplier will also be 2x instead of 1x.
Mobile Experience and Technical Performance
Big Time Gaming slots deliver a smooth, stable experience on mobile phones, largely thanks to a combination of smart design choices and HTML5 technology.
Some of the most noticeable features of most BTG games are oversized symbols, clearly displayed betting interfaces, and spin/bet size buttons that are often coloured differently from the rest of the UI for easier distinction. For example, in Danger: High Voltage, the background is constantly changing between vibrant red, green, yellow, and purple colours, but the spin button and other main controls are always green.
Thanks to HTML5 tech, BTG slots quickly adapt to your screen, regardless of whether you’re playing from an Android smartphone or an iPad. No downloads are required to enjoy Big Time Gaming games from mobile, but plenty of UK casinos that are partnered with BTG offer native apps.
How Did We Test and Rank the Best Big Time Gaming Casinos? (Our Methodology)
To ensure you can access the best BTG online casinos, we’ve handpicked some of the most reputable sites from a list of 30 UKGC-regulated casinos by following these criteria:
- Software Integration
Most online casinos we found didn’t feature the entire BTG library of 85+ games. Top performers typically had a mix of old and new (post-Evolution acquisition) titles, while lower-ranked casinos had only the vendor’s flagships, such as Bonanza Falls and White Rabbit. We also paid attention to how many BTG’s sisters were featured, such as NetEnt, Red Tiger, and Nolimit City, as their games offer slightly more variety outside of video slots and Megaways-focused titles.
- Bonus Fairness
One of the best ways to play BTG slots is with free spins or bonus funds, and fortunately, all legit UKGC casinos now offer very similar bonus rules (due to the newest UKGC regulations, which prevent sites from attaching rollover steeper than 10x). While BTG games aren’t too common features in sign-up bonuses and no-wagering spins, we selected sites where Big Time Gaming slots contribute 100% of each stake toward playthrough progress.
- Payout Speed
Slow payouts spell frustration more than poor mobile optimization or subpar promo offers. We prioritised online casinos that typically need less than 24 hours to process withdrawal requests of verified players – first payouts are always a bit slower, so we repeated our tests with multiple payment methods to determine the average withdrawal speeds accurately.
- Mobile Stability
Evolution has an advanced suite of in-house mobile optimisation technologies, which BTG became privy to after joining its family. No apps or downloads are required to play Big Time Gaming titles, but we gave extra points to platforms like Casumo and Paddy Power, as they offer native mobile apps with exceptional stability and overall performance.
- Licensing Check
All Evolution-owned iGaming studios are operating under Evolution’s UKGC license, but simply being featured among available providers isn’t a guarantee of proper regulation. While reviewing UK casinos, we verified the licenses displayed on their websites by running the numbers against the UKGC database of active licensees.
Big Time Gaming vs. The Competition: UK Market Comparison
With a meticulous approach to slot production, BTG has made “only” 85+ games in over a decade. While new games are released on schedule, it’s not as prolific as, say, Hacksaw or Pragmatic. However, it’s worth mentioning that Big Time Gaming games offer a diverse set of bonus features and are all but recycled classics.
Moreover, BTG is the studio that has changed the iGaming industry with its proprietary Megaways mechanic. They’ve taken it even further with Megapots and Megapays sub-systems, which seamlessly combine with more familiar mechanics like Cascading Reels (Monopoly Deluxe) and Expanding Wilds (Queen of Riches). Most of its competitors use BTG’s Megaways system to develop their own games.
However, Big Time Gaming isn’t exactly competitive in gambling verticals other than slots. This studio has no table games, crash titles, or live dealers. Fortunately, Evolution is the biggest name in the industry when it comes to live games, and most sites that have BTG slots usually have at least a dozen Evolution-made game shows, blackjack, poker, and baccarat rooms.
| Feature | Big Time Gaming | NetEnt | Red Tiger Gaming |
|---|---|---|---|
| Core Strength | Innovative in-game modifiers and bonus triggers | Games with multiple bonuses | High-stakes slots and jackpots |
| Best Known For | Developed the Megaways mechanic | Superb slot RTPs | Catalogue-wide jackpot network |
| Avg. RTP Range | 96-96.50% | 96-99% | 95.76-98.11% |
Are Big Time Gaming Casinos Safe and UKGC Regulated?
Big Time Gaming (or its founding organisation, Big Time Gaming PTY Limited) isn’t directly licensed by the Gambling Commission. Evolution Gaming acquired the studio, which is legally operating under its UKGC license account number 41655.
While this doesn’t mean that all BTG casinos are safe by default, Evolution and its brands only work with fully regulated online casinos in the United Kingdom – we can’t vouch for the safety and quality of offshore brands powered by any Evolution-owned developer.
Frequently Asked Questions (FAQs) for Big Time Gaming Casinos
If you need more help with Big Time Gaming casinos, search for the answers for the most popular questions below.
Queen of Riches, Monopoly Deluxe, and Castle of Terror stand out from BTG’s portfolio with the highest RTP values of 96.90%, 96.84%, and 96.72%, respectively. Most other games by this provider have average RTPs of 96% to 96.50%.
No, Big Time Gaming slots, scratchcards, and Megaways games are RNG-certified in numerous international jurisdictions and in the UK.
When no-deposit bonuses or free spin promotions are available for BTG slots specifically, it’s entirely possible to play Big Time Gaming games for free. Otherwise, you can visit BTG’s official website and demo any titles from its catalogue without any spending.
Although Big Time Gaming doesn’t host a local jackpot network, dozens of its games have exceptionally high maximum win limits. For example, you can win up to 147,620x of your stake in Max Megaways 2, up to 102,840x in Burgers, up to 93,540x in Bonanza Falls, or up to 89,200x in Big Bucks Deluxe.
BTG slots are perfectly optimised for mobile gaming, but online casinos that offer native apps, such as Parimatch, PaddyPower, Midnite, Casumo, or PlayOJO, tend to offer the smoothest experience.
