Bonanza Megaways by Big Time Gaming is the slot that started the Megaways revolution. Released in 2016, it introduced the licensed Megaways mechanic — up to 117,649 ways to win, a cascading/tumble mechanic, unlimited win multiplier during free spins, and a reactive grid. Every Megaways slot that came after it — including The Dog House Megaways in this review series — exists because of Bonanza. A 96.0% RTP, very high volatility, and a 10,000x max win. This is foundational.
How to Play Bonanza Megaways
Bonanza Megaways uses a 6-reel grid where each reel shows 2–7 symbols per spin, creating a variable number of ways to win — up to 117,649 maximum. Additionally, there's a horizontal row of symbols running across the top of the middle 4 reels, adding additional matching positions. Ways wins pay across adjacent reels from left to right.
The mine/gold rush theme is simple and charming: gemstones of different colours (the main symbols) alongside bars, gold bars, and the dynamite scatter. Exactly what a gold mine should look like.
Symbols & Payouts
| Symbol | 6-of-a-Kind Payout (R10 spin) |
|---|---|
| Diamond | ~R1,200 |
| Emerald | ~R900 |
| Ruby | ~R700 |
| Sapphire | ~R500 |
| Gold Bar | ~R350 |
| Bar (triple) | ~R250 |
| Bar (double) | ~R200 |
| Bar (single) | ~R150 |
Large numbers of matching symbols pay dramatically more. An 18-symbol diamond win during free spins with a high multiplier is where the extreme wins originate.
Bet Range in Rands
Minimum bet: R0.20 per spin. Maximum bet: R2,500 per spin.
Feature Breakdown
Cascade Mechanic
When a win forms, winning symbols disappear and new symbols cascade in from above. Consecutive cascades within a single spin build toward free spins via the reaction mechanic in the base game. In free spins, cascades increase a growing multiplier.
Four Scatters for Free Spins
Land 4, 5, or 6 dynamite scatter symbols anywhere on the grid plus the top row:
- 4 scatters: 12 free spins
- 5 scatters: 15 free spins
- 6 scatters: 18 free spins
Free Spins with Unlimited Multiplier — The Defining Feature
This is the mechanic that changed the industry. During free spins, every cascade (not every spin — every cascade within a spin) increases the win multiplier by 1. The multiplier starts at 1x and there is no cap. The multiplier carries across spins.
By spin 10 of 12 free spins, with regular cascades building the multiplier, you might be at 50x. By the end of a retrigger chain, the multiplier can reach hundreds. At 100x or more with a large matching symbol combination, the 10,000x theoretical maximum starts to enter the realm of possibility.
The unlimited multiplier with no ceiling is what makes Bonanza Megaways the original high-ceiling Megaways game. The Dog House Megaways uses a fixed sticky wild multiplier system; Bonanza uses a free-climbing cascade counter.
Free spins can be retriggered by landing 3+ scatters during the bonus. Every retrigger adds more spins while the multiplier continues climbing.
Anticipation Mechanic
Before the scatter lands, locked anticipation animations on potential scatter positions build tension. When the fourth dynamite appears, the reveal animation is one of the most satisfying in slot game history.
No Bonus Buy (Original Version)
The original Bonanza Megaways does not have a bonus buy. This is consistent with BTG's original design philosophy.
RTP & Volatility
RTP: 96.0% Volatility: Very High Max Win: 10,000x stake

The unlimited free spins multiplier with no cap is the source of the very high volatility. Most free spins sessions produce modest results (low multiplier, short cascades). A smaller percentage produce spectacular results (high multiplier, long cascade chains at peak multiplier). The distribution is wide and the 10,000x theoretical maximum has been reached by real players.

| Max Win at R25/spin | R250,000 |
| Max Win at R50/spin | R500,000 |
Myth-Busting
"The multiplier resets to 1x on every free spin." False — and this is the most important mechanic to understand in Bonanza. The multiplier increases with every cascade during free spins and carries across spins. It NEVER resets until the feature ends. By the end of a retrigger chain, the multiplier can be extremely high.
"Bonanza is outdated — the Megaways on newer games are better." The Megaways mechanic originated here and functions identically in principle. The unlimited multiplier in Bonanza's free spins is mechanically distinct from — and in some ways superior to — many newer Megaways implementations that use capped or reset multipliers.
"The 117,649 ways happen on every spin." The maximum 117,649 ways requires every reel to show 7 symbols simultaneously — it's the maximum, not the average. Most spins produce fewer ways. The expectation for a typical spin is roughly 20,000–50,000 ways.
"You need to bet maximum to qualify for the 10,000x win." The 10,000x win is accessible at any bet level. Bet size affects the rand value of wins, not win probability.
Strategy & Tips
Bonanza Megaways requires very high variance bankroll discipline.
Bankroll Sizing
| Bankroll | Recommended Bet | Expected Spins |
|---|---|---|
| R400 | R2.00 | ~200 spins |
| R1,000 | R5.00 | ~200 spins |
| R2,000 | R10.00 | ~200 spins |
| R5,000 | R25.00 | ~200 spins |
Multiplier Tracking During Free Spins
Watch the multiplier counter during free spins. A retrigger at multiplier 30x+ means continuing with a substantial multiplier base — each cascade adds 1 to this high number, producing meaningful wins much faster than a fresh feature starting at 1x.
Stop-Loss
40% of session bankroll for very high variance.
Mobile Experience
Bonanza Megaways was designed for desktop first and the mobile experience reflects its era.
Android: Functional. The variable-height Megaways grid creates an interesting visual dynamic on mobile. The anticipation mechanic before scatter reveals is well-animated. Some older BTG visual design shows on modern high-res screens.
iOS: Works on Safari. The scatter anticipation animation is satisfying on any screen size.
Orientation: Landscape essential for the 6-reel Megaways grid.
Data usage: Moderate — heavier than Habanero but lighter than the most demanding Pragmatic titles.
Graphics & Sound
Bonanza Megaways shows its 2016 origins in its visual design, but the mechanical feedback systems are well-crafted.
Visuals: Simple gem symbols with a mine-cart-running-on-tracks animation above the top row. Colourful gem palette. The anticipation lock mechanic before scatter reveals is the visual highlight — each potential scatter position lights up before revealing whether it's a hit. Not as polished as 2024-standard slots but functional and clear.
Sound: Rock music theme — loud, energetic, and appropriate for the mining chaos. The sound escalates appropriately during the anticipation phase. Cascade sounds build with each consecutive win. Recognisable and memorable.
Overall production quality: 7/10 by 2026 standards. Groundbreaking for 2016. The mechanical feedback systems (anticipation, cascade sounds, multiplier display) are better-designed than most games that came later.

What makes Bonanza Megaways different from other Megaways slots? Bonanza Megaways invented the Megaways mechanic.

This is genuinely different from most subsequent Megaways games that use fixed or capped multipliers.
How does the unlimited multiplier work in Bonanza's free spins? Every cascade win during free spins increases the multiplier by 1. The multiplier carries across spins — it doesn't reset between individual free spins. A retrigger continues from the current multiplier value rather than resetting.
What is the maximum win in Bonanza Megaways? 10,000x your stake. At R10/spin that equals R100,000. At R25/spin it's R250,000.
How do I trigger free spins in Bonanza Megaways? Land 4 or more dynamite scatter symbols anywhere on the 6-reel grid plus the top row.
Does Bonanza Megaways have a Bonus Buy? No. The original Bonanza Megaways does not have a bonus buy feature.
Is Bonanza Megaways still worth playing compared to newer Megaways games? Yes. The unlimited multiplier mechanic is genuinely distinct and in many ways superior to the implementations in newer Megaways titles. The game plays excellently despite its age.

Conclusion
Bonanza Megaways is the slot that changed the industry. The unlimited free spins multiplier mechanic — still not matched in quality by most games that copied the format — combined with the variable Megaways grid create an experience that remains genuinely thrilling in 2026. The 10,000x ceiling is real, the anticipation mechanic is brilliantly designed, and the 96.0% RTP is fair.
For SA players who haven't experienced the original Megaways slot, Bonanza belongs on your list. Play it before you play any of its successors — it makes everything that came after more understandable and more appreciated.
