Bonanza Megaways Slot Review
We have played Bonanza Megaways properly across many sessions, and this Bonanza Megaways slot review is based on real hands-on experience rather than a paytable skim. Released by Big Time Gaming in December 2016, this is the slot that introduced the Megaways mechanic to the world and it still holds up nearly a decade later. With up to 117,649 ways to win on every spin, a 96% RTP, a 26,000x maximum win, and a free spins round featuring an unlimited climbing multiplier, there is a reason this game is still in the library of virtually every online casino on the planet. We cover all of it so you can decide if it belongs in your rotation.

Bonanza Megaways Slot Game Overview
Bonanza Megaways is a 6-reel video slot from Big Time Gaming, released in December 2016 as the game that put the Megaways mechanic on the map. Each of the six main reels displays between 2 and 7 symbols on every spin, and an additional horizontal mine cart reel above reels 2 to 5 adds 4 extra symbol positions on each spin. This combination produces anywhere from 64 to 117,649 ways to win, changing every single spin. The Bonanza Megaways online slot carries a high-volatility rating with an RTP of 96%, sitting right at the industry average. The maximum win is 26,000x your total bet, and that ceiling is only reachable through the free spins feature where the multiplier has no upper limit.
Our review of Bonanza Megaways found the base game more engaging than most high-volatility slots, largely because of the Reactions mechanic. Every time a winning combination lands, the winning symbols explode and new ones tumble in to replace them, potentially creating chain wins from a single spin. The hit frequency sits at 37.47%, meaning roughly one in every 2.66 spins produces something. Most base game returns are small, but the Reactions can occasionally chain into respectable mid-session wins. The rolling banjo soundtrack keeps the energy up between triggers, and the mining theme is sharp and well detailed for a game that is now nearly a decade old.
Bonanza Megaways RTP, Payout, and Volatility
The Bonanza Megaways slot review numbers are clean and straightforward. The RTP sits at 96.00%, which is exactly at the industry average for online slots. That means over a very long run players theoretically get back $96 for every $100 wagered. Big Time Gaming publishes one fixed RTP for this game, so the same maths apply at every casino that carries it. If you use the bonus buy feature, the RTP nudges slightly higher to 96.11%. As always, RTP is a long-term statistical measure across millions of spins and is not a prediction of what you will earn in any given session.
The paytable in the Bonanza Megaways online slot splits into gem symbols and card symbols. The low-paying card symbols, 9 through to Ace, return modest multiples for matching combinations. The high-paying gem symbols step up considerably, with the purple diamond at the top of the table paying 50x your bet for six of a kind across the reels. The wild symbol is a dynamite stick with a lit fuse and substitutes for all standard paying symbols. The maximum win of 26,000x your total bet is among the more generous ceilings in the Megaways category, and it is only achievable through the free spins unlimited multiplier. For reference, Extra Chilli Megaways from the same developer sits at 20,000x, so Bonanza holds its own in the BTG lineup on max win potential.

Volatility in a slot game describes how risky the game is to play. A low-volatility game pays out smaller amounts more often. A high-volatility game pays out less frequently but in much bigger amounts when it does. Bonanza Megaways is firmly in the high-volatility category, though its 37.47% hit frequency makes it noticeably more active in the base game than most other high-volatility titles. Roughly one in every 2.66 spins returns something, which is a relatively high rate for a game of this risk profile. The trade-off is that the vast majority of those base game wins are small amounts from the lower-paying card symbols.
The real weight of the game sits in the free spins round. In the base game, Reactions can occasionally chain into meaningful wins, but these are the exception rather than the rule. The balance between base game and bonus round is heavily skewed toward the feature, where the unlimited multiplier is the engine that drives the game’s top-end potential. A long chain of Reactions during free spins, with the multiplier climbing through 20x, 30x, 50x and beyond, is where the 26,000x maximum win becomes reachable. When the multiplier stalls and the Reactions dry up early in the bonus, the feature can feel underwhelming despite the wait to get there. That is standard high-volatility behaviour.
Bonanza Megaways Special Features and Bonus Options
The Bonanza Megaways online slot bonuses are built around two interconnected systems: the Reactions mechanic that runs through both base game and free spins, and the free spins round with its unlimited climbing multiplier. These two elements work together more elegantly than most slots manage, with each Reaction during free spins both delivering a win and pushing the multiplier higher. The Bonanza Megaways slot game features are lean by modern standards. There is no complex modifier symbol roster, no multiple bonus modes to choose from, and no randomly triggered base game features beyond the standard Reactions. Games like Extra Chilli Megaways from the same studio add a gamble feature and a different scatter system. Bonanza keeps it simpler and is arguably better for it. The free spins round here is one of the most well-regarded in the Megaways genre and has been widely copied but rarely bettered.
Reactions (Cascading Reels)
The Reactions mechanic is the engine that runs through every spin in Bonanza Megaways. When a winning combination lands, all of the winning symbols are removed from the reels in a satisfying rocky explosion. New symbols then fall in from above to fill the gaps, and symbols from the mine cart reel slide in from the top of reels 2 to 5. If the new symbols create another winning combination, those also explode and more fall in, continuing the chain until no new win is formed. A single spin can theoretically produce unlimited Reactions if the symbols cooperate, though in practice chains of 5 or more become increasingly rare.
In the base game, Reactions give every spin a second and third chance to return a win, which is a big part of why the hit frequency is as high as 37.47% despite the high volatility rating. A spin that initially looks like a near miss can chain into two or three separate wins before settling. In the free spins round, Reactions take on additional importance because each one increases the win multiplier by 1. A chain of 8 Reactions in a single free spin would push the multiplier from wherever it started up by 8 additional steps, compounding rapidly on top of whatever was already accumulated. This is what gives the free spins round its enormous upside.
Free Spins with Unlimited Multiplier
The free spins round in Bonanza Megaways is triggered by landing all four GOLD scatter symbols on the horizontal mine cart reel above reels 2 to 5 in the same spin. Landing all four awards 12 free spins. Five scatters awards 17 free spins and six awards 22. Additional scatters can land during the bonus to retrigger more free spins, and there is no upper limit on how many times it can retrigger. The features on Bonanza Megaways online slot during the bonus round include the standard Reactions mechanic plus the unlimited win multiplier, which starts at 1x and increases by 1 with every Reaction. There is no cap on the multiplier at all. If a bonus round produces enough chained Reactions across its spins, the multiplier can reach into triple or even higher figures. A 50x multiplier combined with a full 117,649-way board producing a large symbol combination is the scenario that pushes results toward the 26,000x maximum win. Most bonus rounds produce more modest outcomes, but the theoretical ceiling is genuinely limitless in terms of how high the multiplier itself can climb.
Scatter Symbol and Trigger Mechanic
The scatter symbols in Bonanza Megaways are four gold letters that spell G, O, L, D. They appear exclusively on the horizontal mine cart reel that sits above reels 2, 3, 4, and 5, with one letter appearing above each of those four reels. To trigger the free spins round you need all four letters to appear simultaneously in the same spin, spelling out the full word GOLD. This is a different trigger mechanic to most slots, where scatters land anywhere on the main grid. Here, the four specific positions must all deliver their respective letters at the same time, which makes the trigger feel satisfying and distinctive when it finally lands. There is no partial scatter payout for landing two or three of the letters. You either get all four and trigger free spins, or you get nothing from the scatter positions. The bonus buy feature, added in a later update to the original 2016 release, costs approximately 100x your bet and guarantees immediate entry into 12 free spins. This is not available in all regions.
How To Play Bonanza Megaways
Bonanza Megaways looks more complicated than it is. The shifting reel heights and Megaways counter can seem overwhelming at first, but once you understand that winning just means matching symbols on adjacent reels from left to right, the rest clicks into place quickly. Here is how to get started.
- 1
Set your bet size
Use the controls at the bottom of the screen to choose your stake. Bonanza Megaways accepts bets from $0.20 to $20.00 per spin. The range is narrower than some pokies, but there is enough room to find a stake that suits your session bankroll. Given the high volatility, having at least 100 to 150 spins worth of bankroll at your chosen stake is a sensible starting point. - 2
Spin the reels and watch the Megaways counter
Hit the spin button and watch all 6 reels settle into their random heights between 2 and 7 rows each, plus the 4 symbols on the mine cart reel above. The Megaways counter at the top of the screen shows you how many ways to win are active this spin, ranging from 64 up to 117,649. Winning combinations pay for matching symbols on adjacent reels from left to right. - 3
Watch for Reactions chaining from a single win
When a winning combination lands, those symbols explode and new ones fall in from above. If the new symbols create another win, those also explode, and the process continues. In the base game these Reactions give every spin multiple chances to return a result. Watch the total win counter at the bottom of the screen track across the full chain before settling. - 4
Trigger free spins by landing G, O, L, D on the mine cart reel
The four GOLD scatter letters appear on the horizontal mine cart reel above reels 2 to 5. You need all four letters to appear simultaneously in the same spin to trigger the free spins round. Four GOLD letters awards 12 free spins, five awards 17, and six awards 22. There is no partial payout for landing two or three letters. - 5
Watch the multiplier climb with each Reaction during free spins
During the free spins round, every Reaction increases the win multiplier by 1x. The multiplier starts at 1x and has no upper limit. The longer your Reaction chains run, the higher the multiplier climbs, and it does not reset between spins. Landing more GOLD scatters during the bonus retroactively adds more free spins to keep the round going. This is where the 26,000x maximum win becomes achievable.
Bonanza Megaways Online Slot: Pros and Cons
Bonanza Megaways is one of the most important slots ever released and after spending real time with it in 2026 it still earns its place in any high-volatility player’s rotation. The Reactions mechanic keeps the base game active, the free spins unlimited multiplier remains one of the most thrilling features in the Megaways genre, and the 26,000x max win is a genuine ceiling. The 37.47% hit frequency is unusually high for a high-volatility slot, giving the base game more texture than competitors. On the downside, the visual design has dated since 2016 compared to newer Megaways titles, the max bet of $20 is low for bigger bankroll players, and the free spins trigger only on the mine cart reel with all four GOLD letters landing simultaneously, which can test patience considerably.

Bonanza Megaways Final Thoughts
Bonanza Megaways is a landmark slot that still delivers a quality experience in 2026. Across our testing sessions the base game runs at a satisfying clip thanks to the 37.47% hit frequency and the constant possibility of Reactions chaining from a single win. The unlimited multiplier free spins round remains one of the most genuinely exciting features in the Megaways category. When GOLD lines up across those four mine cart positions and the bonus fires, the sense of anticipation as the multiplier climbs with each Reaction is hard to match. The game has dated visually compared to modern Megaways releases, and the $20 maximum bet limits the dollar value of wins for higher-stakes players. But within those constraints the core experience is as good as it was in 2016.
We recommend Bonanza Megaways to any player who has not yet experienced it and wants to understand what the Megaways mechanic is all about. It is also worth revisiting for veterans who want a reliable, well-balanced high-volatility session without an overwhelming number of features to track. Try the demo first to get comfortable with how the Reactions chain and how the GOLD scatter trigger works. If the base game pace suits you, it is one of the most rewarding slots available when the free spins multiplier gets going. For players chasing the absolute maximum win potential, newer Megaways titles with higher ceilings exist, but few of them have the same track record of delivering meaningful sessions that Bonanza has built over nearly a decade.
FAQ
What is the RTP of Bonanza Megaways?
Bonanza Megaways has a base game RTP of 96.00%, which sits right at the online slot industry average. The bonus buy feature has a slightly higher RTP of 96.11%. Big Time Gaming publishes one fixed RTP for this game and operators cannot configure lower versions, so you get the same maths at every casino carrying it. RTP is a long-term theoretical figure across millions of spins and is not a guarantee of what you will earn in any single session.
How does the free spins feature work in Bonanza Megaways?
The free spins round is triggered by landing all four GOLD scatter letters simultaneously on the horizontal mine cart reel above reels 2 to 5. Four letters awards 12 free spins, five awards 17, and six awards 22. During free spins the Reactions mechanic continues to operate and every Reaction increases the win multiplier by 1x. The multiplier starts at 1x and has no upper limit. Landing more GOLD scatters during the bonus awards additional free spins with no cap on retriggering.
What is the maximum win in Bonanza Megaways?
The maximum win in Bonanza Megaways is 26,000x your total bet. At the maximum stake of $20 per spin, that equates to a potential payout of $520,000. The 26,000x ceiling is only achievable through the free spins round via a large number of chained Reactions that push the unlimited multiplier to very high levels. The original 2016 release had a lower cap of around 10,000x, and the current 26,000x figure was introduced in a later update by Big Time Gaming.
Does Bonanza Megaways have a bonus buy feature?
Yes, Bonanza Megaways has a bonus buy feature, though it was not part of the original 2016 release and was added in a later update. The bonus buy costs approximately 100x your total bet and guarantees immediate entry into 12 free spins. The bonus buy RTP is 96.11%, slightly higher than the base game rate of 96.00%. The bonus buy feature is not available in all regions due to local gambling regulations, including the UK market.
How many ways to win does Bonanza Megaways have?
Bonanza Megaways can produce anywhere from 64 to 117,649 ways to win on each spin. The number changes every spin because each of the 6 main reels randomly displays between 2 and 7 symbols, and the total ways to win is calculated by multiplying the symbol count across all reels. An additional horizontal mine cart reel above reels 2 to 5 adds 4 more symbol positions. When all 6 reels show 7 symbols and the mine cart adds its 4, the maximum 117,649 ways become active.
Is Bonanza Megaways suitable for beginners?
Bonanza Megaways is actually a reasonable choice for players new to high-volatility slots because the Reactions mechanic keeps the base game more active than most comparable titles. The rules are simple enough: match symbols on adjacent reels from left to right and watch the Reactions chain. The main complexity to understand is the GOLD scatter trigger on the mine cart reel. We recommend trying the free demo version first to get comfortable with the Megaways reel structure, the Reactions system, and the pacing before committing real money.
If you enjoy the Megaways format and unlimited multiplier action of Bonanza Megaways, there are several other titles worth exploring. Extra Chilli Megaways from the same Big Time Gaming studio offers a similar Reactions and free spins structure with a gamble feature and a 20,000x max win. White Rabbit Megaways, also from BTG, features an expanding reel mechanic and a higher max win of 13,000x. For Megaways fans who want more volatility and a bigger ceiling, Bonanza Gold Megaways pushes the max win to 50,000x. Here are some popular titles our readers also enjoy.
