What Is Bonanza Megaways
Bonanza Megaways is not a standard pokie. The Megaways mechanic means each of the six main reels displays a random number of symbols on every spin — between 2 and 7 — and the number of active ways to win is the product of all those positions multiplied together, reaching up to 117,649 on the best spin. A horizontal cart reel sits above reels 2 through 5 and adds one extra symbol to each of those positions every spin, contributing to winning combinations and carrying the Wild (dynamite bundle) and, during free spins, extra scatter symbols for retriggers.
The setting is a sunlit gold mine: rocky hillside backdrop, animated waterfall, a timber hut off to one side, and an iconic banjo soundtrack that kicks up tempo whenever the reels spin. Symbols sit on stone blocks, and the art is clean and well-executed even by today’s standards. High-value symbols are gem types — Diamond (top payer at 50x for six of a kind), Red, Blue, and Green gems. Low-value symbols are standard playing card ranks: A, K, Q, J, 10, 9.
This is a game for players who can handle long cold stretches between features. High volatility means wins land on roughly 37% of spins — fewer than most pokies — and the base game rarely pays meaningfully on its own. The game’s value lives almost entirely inside the free spins round. If you’re looking for steady session action, look elsewhere. If you’re chasing a feature where the multiplier runs past 20x or 30x, Bonanza is one of the best games ever designed for exactly that.
RTP and Volatility
The RTP is 96.00% in the base game — right on the industry average. Over millions of spins, the game theoretically returns $96.00 per $100 wagered, but that figure masks enormous session-to-session variance. With high volatility, your $20 session at minimum bet can go to near zero before a bonus fires, or it can hit 50–100x your stake inside a single well-multiplied free spins round. The 26,000x maximum win exists, but it requires sustained Reaction chains pushing the multiplier deep into three digits during free spins — a rare event.
The Bonus Buy feature (where available) carries a slightly higher RTP of 96.11%, reflecting the guaranteed feature entry. The hit frequency is approximately 37.5% — meaning fewer than 4 in 10 spins produce any win in the base game. Most of those wins are small. Plan your session budget around the feature, not around base-game accumulation.
Betting Range
Bets run from $0.20 to $20 per spin. The $0.20 minimum is very accessible and makes sense for high-volatility play — you want enough spins to weather dry stretches and give the feature a chance to fire. At $0.20 a spin, 100 spins costs $20 flat. The $20 maximum is modest; this isn’t a game designed for large-stake high-rollers, though the 26,000x ceiling means even a $1 spin can theoretically return $26,000 in a premium free spins run. The Bonus Buy option (where available in your jurisdiction) costs approximately 100x your bet to instantly trigger 12 free spins.
How to Play Bonanza Megaways — Step by Step
- Set your bet using the stake selector. Start at $0.20 if you’re new to the game — high volatility means you need enough spins to reach the feature.
- Hit spin. The six main reels each show a random number of symbols (2–7), and the cart reel above reels 2–5 adds one symbol per position. The total ways to win for that spin is calculated automatically — anywhere from a few hundred to 117,649.
- Any winning combination triggers a Reaction: winning symbols explode, new ones drop in from above and slide in from the cart reel. If the new symbols form another win, another Reaction fires. This chains until no new wins appear.
- Watch the cart reel for the G, O, L, D scatter tiles. You need all four to land anywhere on the reels (including the cart reel) in a single spin or cascade sequence to trigger free spins.
- Each scatter beyond the four that triggers free spins adds 5 more free spins to your starting total of 12.
- In free spins, every Reaction increments the win multiplier by 1x. It starts at 1x and never resets for the entire round — a chain of 10 Reactions across several spins builds a 10x multiplier that applies to all subsequent wins.
Try this: Start with 100 spins at $0.20 as a baseline session — at ~37% hit frequency you’ll see base-game activity regularly, and the GOLD scatter trigger averages roughly every 150–200 spins, so a $30–$40 budget at minimum bet gives you a realistic shot at the feature.
Bonus Features
Reactions (Cascading Wins)
Every win in Bonanza — base game or free spins — triggers a Reaction. Winning symbols explode off the reels, and new symbols fall in from two directions: from above the main reels, and sliding in from the right via the mine cart above reels 2 through 5. If those new symbols form another winning combination, another Reaction fires. The chain continues until no new wins form. A single spin can produce five, ten, or more consecutive Reactions if the symbols cooperate — each counted separately, each paying out. In the base game, Reactions don’t carry a multiplier. In free spins, each one builds the multiplier.
Free Spins with Unlimited Win Multiplier
Land all four GOLD scatter tiles — G, O, L, D — anywhere on the reels in a single spin or cascade sequence to trigger 12 free spins. Each additional GOLD scatter beyond the triggering four adds 5 more free spins before the round starts.
During free spins, every Reaction increases the win multiplier by 1x. The multiplier starts at 1x and never resets for the entire round — it carries forward through every spin. A round that starts with three Reactions on spin 1 runs spin 2 at 3x. By spin 8 with consistent Reaction chains, a 15x–25x multiplier is plausible. With retriggers extending the round, 50x+ is achievable. The multiplier has no cap; the overall win is capped at 26,000x stake.
Retriggers happen during free spins via the cart reel above reels 2–5. Landing 3 cart scatters adds 5 more free spins; landing 4 adds 10 more spins. There is no limit on how many times you can retrigger — a long run with consistent retriggers and Reactions is the path to the game’s biggest payouts.
Wild Symbol
The Wild is a bundle of dynamite sticks and appears exclusively on the horizontal cart reel above reels 2 through 5. It substitutes for all symbols except the GOLD scatter tiles. Because it sits on the cart reel, it contributes to winning combinations on reels 2, 3, 4, and 5 and can be the difference between a winning and losing Reaction chain.
Bonus Buy
Where available (not in the UK or all jurisdictions), the Bonus Buy lets you skip straight to 12 free spins for approximately 100x your current bet. The RTP on this feature is 96.11% — marginally higher than the base game’s 96.00%. It’s a legitimate option if you’re specifically chasing the multiplier feature and don’t want to grind the base game, but the cost is significant at higher bet sizes.
About Big Time Gaming
Big Time Gaming was founded in Sydney, Australia in 2011 by Nik Robinson. They invented the Megaways mechanic — first used in Dragon Born (February 2016), then popularised by Bonanza (December 2016). The mechanic was so successful that BTG licensed it to dozens of other developers including Pragmatic Play, NetEnt, Blueprint Gaming, and Red Tiger, spawning hundreds of Megaways titles. Evolution Gaming acquired BTG in 2021 for approximately €450 million. BTG’s other notable titles include Extra Chilli Megaways, White Rabbit, Danger High Voltage, and the Bonanza spin-offs: Bonanza Megapays and Bonanza Falls.
Is Bonanza Megaways Worth Playing
Pros:
- 26,000x max win is genuinely achievable via the unlimited, non-resetting multiplier — one of the highest ceilings available at 96% RTP
- Up to 117,649 Megaways creates real variability in every spin — no two spins play the same
- Reactions mechanic chains consecutive wins from a single spin, amplifying the multiplier faster than one Reaction per spin
- Retriggerable free spins with no limit on extra spins or multiplier growth
- $0.20 minimum bet makes extended high-volatility sessions viable on a modest budget
- The banjo soundtrack and mining theme are iconic — genuinely distinctive and well-executed
- Bonus Buy (where available) gives direct access to the feature at 96.11% RTP
Cons:
- High volatility means long cold spells between features — the ~37% hit frequency is among the lower end for online pokies
- Base game wins are almost always small; the game only justifies its reputation inside the free spins round
- $20 maximum bet is low for players who want to scale the 26,000x potential to meaningful dollar amounts
- Bonus Buy not available in the UK and some other jurisdictions
- Graphics, while still charming, are dated compared to current-generation BTG and competitor titles
- Feature trigger frequency averages 1 in 150–200 spins — expect patience and budget discipline before the bonus fires
Bottom line: Bonanza Megaways earned its reputation honestly. The unlimited multiplier inside a Reaction-driven free spins round is still one of the best-designed bonus mechanics in online pokies, and the 26,000x ceiling is real for patient players who let the multiplier build. It’s not a game for short sessions or small bankrolls relative to the bet size. At $0.20 a spin with a $40 session budget, you’re giving yourself a genuine shot at the feature. If the multiplier runs, you’ll understand why this game changed the industry.
Responsible Gambling
Bonanza Megaways uses a certified Random Number Generator (RNG). Every spin result, including the number of symbols on each reel, is independently and randomly determined. The 96% RTP is a long-run theoretical figure — short sessions can diverge significantly from it in both directions. High volatility means losing sessions are common. Set a fixed budget before you start, decide your session length in advance, and stop when either limit is reached.
