Big Time Gaming Slots: The Megaways Studio at Slots99
Big Time Gaming, often shortened to BTG, is the studio that invented Megaways, and this page gathers every one of its games we carry. That means the originals, Bonanza, Extra Chilli and White Rabbit, plus Danger High Voltage, the Megapays remakes and dozens of themed releases. Can you try them free? Yes: every Big Time Gaming slot here opens in demo mode, with no account and no deposit. You must be 18 or over to play at Slots99.
What makes this corner of the catalogue distinctive is its maths. Most of the studio's games here carry a High volatility record, a few sit at Medium-high, and a small group, Bonanza and White Rabbit among them, are recorded as Medium. Below you'll find the games sorted by mechanic, by theme and by recorded volatility, followed by a step-by-step guide to how they actually play.
Which Big Time Gaming slots can you play at Slots99?
Slots99 is an online casino with 3,000+ slots from 20+ studios, and Big Time Gaming is one of them. The grid on this page holds every BTG title in our catalogue and nothing from any other studio. If a game you know isn't in it, we don't carry it, however famous it is. The catalogue changes over time, so the grid is always the current answer.
The games fall into four rough groups. The Megaways originals made the studio's name: Bonanza, Extra Chilli and White Rabbit. The Megapays titles rebuild familiar games with a jackpot layer, as in Bonanza Megapays and Danger! High Voltage Megapays. The other in-house mechanics include Megaclusters in Cyberslot Megaclusters and Spinfinity in Temple Quest Spinfinity. Finally, a long run of themed Megaways releases covers everything from Rasputin Megaways to the seasonal Christmas Bonanza.
Danger High Voltage sits slightly apart from all four: it's a BTG original that doesn't use Megaways at all, and it has a following of its own. If you'd like to see how this studio sits next to the others we carry, the providers page lists them side by side.
How Megaways works, from the studio that invented it
On a classic slot, every reel shows the same number of symbols on every spin, and wins follow fixed paylines. Megaways drops both rules. Each reel lands a different number of symbols each time you spin, so one reel might show a tall stack while the next shows only a couple. The number of ways to win is the symbol counts of all the reels multiplied together, so it changes from spin to spin as well.
Wins are counted on adjacent reels starting from the left, and a symbol's height on its reel doesn't matter. That's why a Megaways screen can look crowded and still pay: matching symbols on neighbouring reels count wherever they land. Many of the studio's Megaways games also run an extra horizontal reel across the top of the middle reels, which adds symbols to the count. Most use cascades, where winning symbols drop away and new ones fall into the gaps.
Big Time Gaming licenses Megaways to other developers, so you'll meet the mechanic well beyond this page. The studio's own versions are still the reference point the others get measured against. Details vary by title, and each game's own rules take precedence over any summary, this one included. Our Megaways collection gathers the Megaways titles we carry in one view.
Play any Big Time Gaming slot free in demo mode
Every Big Time Gaming slot on this page opens in demo mode. You don't need an account or a deposit, and the demo runs the same maths as the real-money version. If you're in Canada, where free slots are among the most searched casino topics, that puts the whole studio within reach before you sign up for anything.
Demo play is especially useful here, because so much of this studio is recorded as High volatility. On those games the feature can take a long time to arrive, and a short session tells you almost nothing. Give a game a few hundred demo spins and you'll get a fair sense of its rhythm: how often cascades chain together, how far the ways count swings, and what the base game feels like between features. That's what you want to know before you choose a real-money stake.
The all slots page covers what demo mode shows and what it doesn't. The practical tip for this studio is simpler. Open Bonanza and one of the High volatility titles side by side in demo, play each for a while, and you'll feel how differently the same studio can pace a session.
How to play a Big Time Gaming slot
Here is how a typical Big Time Gaming Megaways game plays, one step at a time. It fits Bonanza, Extra Chilli, White Rabbit and most of the themed titles. The Megaclusters and Spinfinity games follow their own rules, which are set out in each game's information panel.
Open the rules screen before your first spin
Every game has an info or rules screen, usually behind a menu button. It shows the paytable, how the feature triggers, the maximum win and the return-to-player figure the game declares. It also tells you which optional extras that version of the game includes, so you never have to guess.
Set a stake that fits your session
Choose your bet per spin with the stake control. On a High volatility game a smaller stake is often the better choice, because the gaps between features can be long and your budget needs to cover them. Decide what the session can cost before you start, then pick a stake that lets it last.
Read the ways counter
Most of the studio's Megaways games show the current number of ways on screen, close to the reels. Watch it for a few spins. When the tall reels line up the count jumps, and when several reels land short it drops. You don't control it: it's simply a readout of the shape the reels took on that spin.
Follow the cascade
When a spin wins, the winning symbols usually vanish and new ones drop in, which can set off another win on the same spin. Bonanza calls these reactions. In several of the studio's games the free spins add a win multiplier that climbs as the cascades continue, which is why the feature is where most of the excitement sits.
Learn what triggers the feature
Each game has its own trigger. In Bonanza you collect scatter letters that spell GOLD; other titles use scatter symbols in the familiar way. The paytable shows the trigger, and the demo shows you how it tends to land in practice.
Move to real money at the stake you practised
When you switch from demo to real money, start at the stake you used in demo, so the game behaves the way you already know. Set a point at which you'll stop, win or lose, and keep to it.
The originals: Bonanza, Extra Chilli and White Rabbit
Bonanza is the game that made Megaways famous: a gold-mining slot with cascades and the extra horizontal reel along the top. Its free spins come from spelling GOLD with scatter letters, and during the round a win multiplier rises with every cascade. Our catalogue records Bonanza as Medium volatility. That's the label we go by, whatever you may have read elsewhere, and it makes Bonanza a sensible first stop if you're new to the studio.
Extra Chilli moves the same engine to a chilli-pepper theme with bright, busy reels. It's recorded as High volatility. Its free spins round offers a gamble: you can risk the spins you've won for the chance of a longer round, or take what you have and play it. The rules screen sets out exactly how that choice works.
White Rabbit borrows its world from Alice in Wonderland. In its free spins the reels can grow taller, which opens up more ways as the round goes on. Like Bonanza, it's recorded as Medium volatility. With all three, details vary by title, and each game's own rules take precedence over any description here.
Danger High Voltage and the Megapays remakes
Danger High Voltage is loud, bright and built on fixed reels rather than Megaways. When its feature lands, you choose between two free-spins rounds with different wild rules, so the game hands you a real decision at its most important moment. It's recorded as High volatility.
Megapays is the studio's name for Megaways games with a jackpot layer on top. Danger! High Voltage Megapays rebuilds the original around that system, and Bonanza Megapays does the same for the mining game. Both are recorded as High volatility. That's worth noticing: Bonanza itself is recorded as Medium, so its Megapays version is a different proposition, not a fresh coat of paint.
How the jackpot side triggers and pays differs from game to game, so read the rules panel before you play; it's the authority on every detail. If you enjoy an original, try it and its remake back to back in demo and see which pace you prefer.
Megaclusters and Spinfinity: the studio's other mechanics
Big Time Gaming doesn't stop at Megaways. Cyberslot Megaclusters uses Megaclusters, a cluster-pays grid in which symbols that form a win split into smaller ones, so the grid gets denser as a cascade runs. It's recorded as High volatility and sits in our cosmic collection next to Star Clusters, which is also recorded High.
Temple Quest Spinfinity carries Spinfinity, another of the studio's own mechanics. It's recorded as Medium volatility, one of the few titles from this studio at that level. Its rules panel explains how Spinfinity shapes the feature. As with Megaways, Megapays and Megaclusters, the details vary by title and the game's own rules take precedence.
Big Time Gaming slots by theme
The studio's settings range widely, from mining camps to outer space. Here's where its games sit across our 15 collections, so you can follow a theme you already like.
Animals: King of Cats, Beef Lightning and Gifts Of Fortune are Megaways titles recorded as High, and all three sit in the animals collection. Gifts Of Fortune also appears in the asian collection.
Adventure and magic: The Race and Rasputin Megaways are recorded High. Dragon Born is recorded as Medium and appears in both the adventures and magical collections. Wild Flower, recorded High, is in the magical collection too.
Space: Over The Moon, Wild Portals and Max Megaways join Cyberslot Megaclusters and Star Clusters in the cosmic collection, all of them recorded High.
Lighter themes: the goofy collection takes in Spicy Meatballs, Chocolates, Pop and Vegas Rush, all recorded High, plus Gold Megaways, recorded Medium-high, and Danger! High Voltage Megapays.
Sea, fruit, pirates and the frontier: Golden Catch (High) is in the marine collection. Diamond Fruits (Medium) is in fruits, Pirate Pays (High) is in pirates, and Bonanza Megapays sits in the western collection.
The Big Time Gaming slots list, by recorded volatility
This is the studio's list as we carry it, grouped by the volatility each game is recorded with. We state only what's recorded, never a guess, so use it as a map of where the studio's games sit.
- High: Beef Lightning, Bonanza Megapays, Chocolates, Christmas Bonanza, Cyberslot Megaclusters, Danger High Voltage, Danger! High Voltage Megapays, Donuts, Extra Chilli, Gifts Of Fortune, Golden Catch, King of Cats, Kingmaker, Lil Devil, Max Megaways, Million Rush, Millionare, Opal Fruits, Over The Moon, Pirate Pays, Pop, Rasputin Megaways, Royal Mint, Spicy Meatballs, Star Clusters, Survivor, The Final Countdown, The Race, Vegas Megaways, Vegas Rush, Wild Flower and Wild Portals.
- Medium-high: Book Of Gods, Gold Megaways, Holy Diver and Slot Vegas.
- Medium: Bonanza, Diamond Fruits, Dragon Born, Millionaire Mystery Box, Temple Quest Spinfinity, White Rabbit and the Lucky Streak sequel.
The pattern is plain: this is a High volatility studio first, with a small Medium group led by Bonanza and White Rabbit. On most of these games that means longer runs without a feature and bigger swings when one lands. If you want the gentler end, start with the Medium titles. If you want the studio at full strength, the High list is most of the catalogue.
Big Time Gaming slots on mobile: tips for South African players
Big Time Gaming builds its games to run in a mobile browser, so on a phone you open them the same way you would on a laptop, demos included. Everything in the how-to-play steps above works the same on a small screen.
If you're in South Africa, where mobile data is a real cost for many players, a couple of habits help. The first load of a game is usually the heaviest, because that's when its graphics come down. Once it's open, each spin moves far less data. So open a game on Wi-Fi when you can, and stay with it rather than hopping between titles over mobile data. A demo session is also the cheapest way to find out which BTG game you actually enjoy before you spend data, or money, on the rest.
Paying in from Canada or South Africa
Slots99 accounts run in USD, EUR and CAD. Canadian players can keep everything in Canadian dollars and deposit with Interac, as well as debit and credit cards, direct banking and Revolut. There's no rand account, so South African players choose USD or EUR. Both markets can also use crypto: USDC, BTC, ETH and SOL.
If fast withdrawals matter to you, check each method's details on the payment methods page before you deposit. Big Time Gaming winnings are paid out like any other slot winnings, because the studio supplies the games and has no part in how or when you're paid. Slots99 is operated by Disrupt Entertainment Limited N.V. (registration 140327) under licence OGL/224/668/0844. Check the rules that apply where you live before you play for real money.
Bonuses and Big Time Gaming slots
The welcome offer runs to $1,500 across three deposits, from a $10 minimum, with 40x wagering. The bonus conditions page has the full terms, and the promotions page lists what else is running. The bonus play page lists around 1,700 games, so check there whether a given Big Time Gaming title is among them before you plan around it.
One rule matters more on this studio than on most: while you're wagering the welcome bonus, the maximum bet is $5 per spin. On a High volatility game it's tempting to raise your stake when a feature feels close. With bonus funds you can't, and in any case features never come due: every spin is independent of the last. Pick a stake inside the limit and let the session run at that pace.
Is there a Big Time Gaming login?
No. Big Time Gaming makes games and supplies them to casinos. It doesn't run player accounts, so there's no Big Time Gaming or BTG casino login to look for. You sign in to the casino where you play. At Slots99, you don't need to sign in at all to try the demos; you only need an account to play for real money.
If you can't get into your Slots99 account, support answers seven days a week at [email protected]. Be wary of any site that presents itself as an official Big Time Gaming casino. The studio's games appear at many casinos, but it doesn't operate one.

Can I play Big Time Gaming slots for free?
Yes. Every Big Time Gaming slot here opens in demo mode with no account and no deposit, and the demo runs the same maths as the real-money game. It's the easiest way to learn a High volatility title before you stake anything.
Did Big Time Gaming invent Megaways?
Yes. Megaways is Big Time Gaming's own mechanic, Bonanza is the game that made it famous, and the studio licenses it to other developers. Each reel lands a different number of symbols on every spin, so the number of ways to win changes every spin too.

Does Slots99 rank Big Time Gaming slots by return?
No. Each game declares its own return-to-player figure, which you'll find in the game's information panel. We don't rank or sort the studio's games by it. What we do show is each game's recorded volatility, which tells you more about how a session is likely to feel.
Which Big Time Gaming slots are recorded as Medium volatility?
Bonanza, White Rabbit, Dragon Born, Diamond Fruits, Millionaire Mystery Box, Temple Quest Spinfinity and the Lucky Streak sequel. Book Of Gods, Gold Megaways, Holy Diver and Slot Vegas are recorded as Medium-high. Most of the rest of the studio is recorded as High.
Can I buy the bonus round in Big Time Gaming slots?
We don't record which versions offer a bonus buy, so we won't promise one. Open the game's info screen: it shows whether that game includes the option.
What's the difference between Danger High Voltage and the Megapays version?
Danger High Voltage is the original on fixed reels, with a choice of two free-spins rounds. Danger! High Voltage Megapays rebuilds it as a Megaways game with a jackpot layer added. Both are recorded as High volatility, and the rules panel in each sets out exactly how its features work.
Can I use bonus funds on Big Time Gaming slots?
Check the bonus play page to see whether the title you want is on it. While you're wagering the welcome bonus, the maximum bet is $5 per spin, and the bonus conditions page has the full terms.
Can I play Big Time Gaming slots on my phone?
Yes. The games run in your mobile browser, demos included. If you're watching your mobile data, open the game on Wi-Fi first, since the first load is the heaviest.
Which studios should I try after Big Time Gaming?
Searchers often move on to Hacksaw Gaming and Pragmatic Play, and both have pages here, as does Relax Gaming. If it's Megaways you want, the Megaways collection covers the titles we carry with that mechanic.
Play for fun, within limits
Big Time Gaming's games are built to be exciting, and a High volatility slot can move quickly in both directions. Treat every session as entertainment you can afford to lose, never as income and never as a way to win back a loss. Set a budget and a time limit before you start, take breaks, and stop when you reach either one. The responsible gaming page sets out the tools and support available if you want to change how you play.
