Big Time Gaming invented Megaways. That's not marketing — it's a matter of record. The mechanic that powers Bonanza, Extra Chilli, Millionaire, and hundreds of licensed titles from other studios was created by BTG and patented in 2016. If you've ever played a slot with a variable reel that shows a different number of symbols on every spin, you've experienced the engine that BTG built. This guide covers what BTG brings to the SA market and how to get the most from their catalogue.
Big Time Gaming slots South Africa — the full breakdown.
Who Is Big Time Gaming?
Big Time Gaming was founded in 2011 in Sydney, Australia by Nik Robinson, who remains the company's CEO. They are independently owned and operated — no parent company consolidation here. They hold licences from the UKGC, MGA Malta, Gibraltar, and several additional jurisdictions, with distribution through major aggregation platforms that supply SA-facing operators.
The studio is small by industry standards — approximately 50–100 employees — but their output per head is extraordinary. Bonanza Megaways (2016) is one of the five most commercially significant slots ever released. Extra Chilli, White Rabbit, and Millionaire are each landmark titles in their own right. The Megaways engine has been licensed to over 100 other studios including Pragmatic Play, Red Tiger, and iSoftBet, generating ongoing royalties while BTG continues to produce original content.
In 2021, Evolution Gaming Group acquired a significant stake in BTG, though BTG continues to operate independently with Nik Robinson retaining operational control. Their games are available at the majority of SA-facing online casinos that carry a premium slot selection.

Why SA Players Love Them
The Megaways mechanic is the reason, and once you understand what it actually does, the appeal is obvious.
Up to 117,649 ways to win on every spin. Traditional slots have fixed paylines — 10, 25, or 243 ways at most. Megaways uses a variable reel mechanic where each reel can display 2–7 symbols on any given spin. With six reels each showing up to 7 symbols, the number of active ways to win on a single spin can reach 117,649. On a spin where all six reels show maximum symbols, you have almost 120,000 individual win paths active simultaneously. When a big win combination hits across a Megaways grid at maximum expansion, the win calculation is genuinely difficult to follow in real time — which is exactly the kind of moment SA players share in casino communities.
Unlimited free spins multipliers. Bonanza Megaways' defining mechanic is an unlimited escalating multiplier during free spins — it starts at 1x and climbs by 1 with every tumble (cascade win). There is no cap. In a well-executed free spins run with multiple tumble chains, the multiplier can reach 50x, 100x, or higher. The 10,000x max win on Bonanza is a function of this mechanic applied to a maximum ways grid at high multiplier. No other mechanic in mainstream slots produces this type of open-ended escalation.
High variance with genuine ceiling access. BTG titles are extreme variance by design. Extended base game drought between features is not exceptional — it's the expected experience. But when features hit on a well-configured Megaways grid, the win potential is top-tier. For SA players with adequate bankrolls and high variance tolerance, BTG delivers the kind of ceiling access that justifies the dry spells.
The originality factor. BTG creates mechanics, they don't replicate them. White Rabbit's vertical reel expansion, Extra Chilli's gamble feature on free spins, Millionaire's quiz-show bonus game — these are genuinely novel implementations. For players interested in mechanics rather than just outcomes, BTG is one of the most intellectually engaging studios available.
RTP & Volatility Profile
Catalogue RTP range: 95.67%–97.72% across the reviewed titles, with most clustering around 96.0%–96.4%.
BTG's RTP spread is wide: White Rabbit's 97.72% is among the highest of any slot at SA casinos, while Danger! High Voltage's 95.67% is below the industry average. Bonanza Megaways at 96.0% is the baseline for the flagship Megaways experience.
| Volatility Tier | Representative Titles |
|---|---|
| High | Millionaire, Danger! High Voltage |
| Very High | Bonanza Megaways, Extra Chilli, White Rabbit |
BTG does not produce low or medium volatility titles in their original catalogue. Everything they build runs hot. Extended base game sessions without a feature trigger — 200, 300 spins — are part of the BTG experience and should be planned for, not surprised by. Read our slot volatility guide and size your session bankroll to at least 200x your bet before loading any BTG title. For extreme-variance consideration, budget 300x+.
RTP variant warning: SA casinos may configure BTG titles at lower RTP settings than the provider defaults above. Always verify the active RTP in the game info panel before playing. White Rabbit's 97.72% in particular — confirm it's available at provider default before playing on that basis.
Max win ceiling: Millionaire at 50,000x is the headline — the second-highest mainstream max win available at SA casinos behind Dead or Alive 2's 100,000x. Extra Chilli at 20,000x and Bonanza at 10,000x follow. BTG's ceiling access is among the highest of any studio in the SA market.
Mobile Experience
All current BTG titles are built in HTML5 and play in-browser on Android Chrome and iOS Safari without download. The Megaways mechanic presents specific mobile rendering challenges that BTG has addressed with varying degrees of success.
Bonanza Megaways on mobile: The variable-height reel system — reels expanding and contracting between spins — is demanding to render. On flagship devices it's smooth and visually impressive. On mid-range Android it runs well with occasional frame rate variation during maximum expansion. On budget devices, the reel expansion animation may stutter. Landscape orientation is required — the 6-reel Megaways grid is unreadable in portrait.
Extra Chilli Megaways on mobile: Similar performance profile to Bonanza. The gamble mechanic interface is well-optimised for touch — the decision moment (bank or gamble) is a satisfying tap interaction.
White Rabbit on mobile: The vertical reel expansion — reels growing taller than the standard 7 symbols — is the most demanding rendering challenge in the BTG mobile catalogue. Flagship devices handle it beautifully. Mid-range Android handles it adequately. Budget devices may struggle during the most aggressive vertical expansions.
Millionaire on mobile: The quiz-show bonus interface is touch-optimised and clean. The bonus game feels genuinely interactive on mobile — tapping through answer options at increasing stakes. The main grid is standard and lightweight.
Performance by device tier:
- Flagship phones (Samsung S-series, iPhone 14+): All titles run flawlessly including White Rabbit at maximum vertical expansion.
- Mid-range Android (Samsung A-series, Xiaomi Redmi): Good performance across the catalogue. White Rabbit may show minor frame rate variation.
- Budget Android: Bonanza and Millionaire run adequately. White Rabbit and Extra Chilli may experience performance issues during peak feature activity.
Data usage: Higher than Habanero, comparable to Pragmatic Play cluster pays. Budget 30–45MB per 100-spin session on Megaways titles. Millionaire is lighter.
New Releases
BTG releases at a slower pace than Pragmatic Play or Play'n GO — typically 2–4 titles per quarter rather than per month. Quality over quantity is the evident philosophy.
Current directional trends:
- Megaways evolution — BTG continues to iterate on the base Megaways engine with new modifiers, bonus structures, and reel configurations. Each new Megaways title from BTG attempts to add something the previous version didn't have.
- Non-Megaways originals — Danger! High Voltage established that BTG can produce compelling non-Megaways titles. Subsequent releases have explored cluster pays and other mechanics outside the core Megaways IP.
- Licenced content — BTG has pursued licenced IP (Extra Chilli drew on recognisable imagery, Danger! High Voltage used the Electric Six track) as a differentiator. More licenced titles are expected.
New BTG releases arrive at SA-facing operators within 2–6 weeks of global release. Their slower pace means less frequent new content but generally higher production value per release.
BTG vs the Competition
BTG vs Pragmatic Play
Different propositions. Pragmatic Play produces cultural moments — Gates of Olympus screenshots in group chats, Sweet Bonanza on every lobby banner. BTG produces mechanical innovation — Bonanza's unlimited multiplier is a more intellectually interesting mechanic than anything in the Pragmatic Play catalogue even if it generates fewer social media moments. Max win ceiling: BTG wins (Millionaire's 50,000x vs Gates of Olympus 1000's 25,000x). Production spectacle: Pragmatic Play wins. Release pace: Pragmatic Play wins significantly.
BTG vs NetEnt
BTG is the active innovator; NetEnt is the legacy institution. BTG's Megaways engine has more ongoing industry influence than anything NetEnt has produced in the last decade. NetEnt counters with White Rabbit-matching RTP (their Blood Suckers at 97.66% vs White Rabbit's 97.72% — essentially tied) and Dead or Alive 2's 100,000x ceiling which exceeds even Millionaire's 50,000x. For current mechanical innovation: BTG. For the absolute ceiling and legacy prestige: NetEnt.
BTG vs Play'n GO
BTG wins on max win ceilings and mechanical originality. Play'n GO wins on catalogue breadth and release pace. The Megaways engine is a more fundamentally innovative mechanic than the Book mechanic, even if Book of Dead is more widely played at SA casinos. Bankroll requirements are comparable — both studios produce very-high variance flagships that need 200x+ session bankrolls.
Verdict
Big Time Gaming is the most mechanically innovative studio available to South African players. The Megaways patent is not a historical footnote — it's the foundation of an ongoing revolution in slot design that BTG continues to lead with each original release. Bonanza Megaways is one of five slots that genuinely changed the industry; Millionaire's 50,000x ceiling is second only to Dead or Alive 2 among mainstream SA options.
The honest caveat is that BTG titles are for serious bankrolls. The unlimited multiplier in Bonanza means extreme variance by design — sessions without a feature trigger stretch longer than any other studio reviewed here. A R200 session might not produce a single bonus. That's the cost of admission for the ceiling access BTG provides.
For SA players with R1,000+ session budgets, high variance tolerance, and genuine interest in how slot mechanics work: BTG is essential. For players managing R50–R300 sessions who need frequent wins to stay engaged, the bankroll mismatch is real.
Best for: R1,000+ session budgets · players chasing 10,000x–50,000x ceilings · high variance enthusiasts · players interested in mechanical innovation Not ideal for: Sub-R500 bankrolls · players who need frequent feature triggers · anyone new to high-variance play
