Theme, studio and what makes the format different
Bonanza Megaways is set on a rocky hillside with a waterfall and a miner's hut, fitting the gold-mining theme. The game was developed by Big Time Gaming, an Australian studio known for creating the Megaways engine.
The layout is not a standard 5x3 grid. You get six reels that display between 2 and 7 symbols each, plus an extra horizontal reel above reels 2 to 5. That extra reel can land wilds. Because the number of symbols on each reel changes with every spin, the total number of ways to win varies. It can go up to 117,649 ways, which is far more than the fixed paylines of a typical pokie.
Winning combinations are formed on adjacent reels from left to right, and the cascading wins feature removes winning symbols and refills them from mine carts above the reels. This can create a chain of wins on a single spin.
Setting up a spin: stakes and controls
To play Bonanza Megaways, set your bet using the selector, which ranges from $0.20 to $20 per spin. The game uses a 6-reel layout where each reel shows between 2 and 7 symbols, plus an extra horizontal reel above reels 2 to 5. Wins are formed by matching symbols on adjacent reels from left to right, and the number of ways to win changes with each spin, up to 117,649. The paytable and game rules are available via the info button, and the spin button starts a round. There is no ante bet or bonus buy option, so the cost per spin is simply your chosen bet.
Bankroll maths: bet sizing for your session
Bonanza Megaways is a high volatility game. That means wins come less often, but when they do, they can be larger. For a session, you need to plan for the swings.
With a minimum bet of $0.20 and a maximum of $20, you have a wide range. For a $50 session, a bet of $0.50 gives you 100 spins. That is a reasonable starting point. For a $200 session, you could bet $1 to $2 per spin, giving you 100 to 200 spins.
There is no bonus buy or ante bet in this game, so the cost per attempt at the free spins is simply your normal bet. The trigger requires 4 scatters, which is rare.
No betting system changes the RTP. The game's return is fixed by the math, so the main thing you control is how many spins you can afford.
Free spins, multipliers and specials
The key features in Bonanza Megaways are:
- Reactions (cascading wins): When you get a winning combination, the symbols involved disappear and new symbols fall from the mine carts above. This can lead to multiple wins from one spin.
- Unlimited win multiplier in free spins: During free spins, the multiplier increases by 1 for every reaction. There is no cap, so it can grow large if you keep the wins coming.
- Free spins trigger: Land 4 scatter symbols to spell G-O-L-D and receive 12 free spins. Each extra scatter adds 5 more spins.
- Retrigger: If you get 3 or more scatters during free spins, you get 5 additional spins.
- Extra horizontal reel: The reel above reels 2–5 can land wilds, which substitute for other symbols to help form wins.
- No bonus buy: There is no option to purchase free spins directly.
A worked example: Suppose you start a free spin with a multiplier of 1. A reaction gives you a win, so the multiplier becomes 2. Another reaction on the same spin increases it to 3, and so on. The multiplier applies to all wins during that spin, and it carries over to the next free spin.
The numbers that matter: RTP and max win
The default RTP for Bonanza Megaways is 96.0%. The official Big Time Gaming page does not publish a range, so this is the figure to work with. If a lower RTP version exists, the difference matters. For example, a version at 95.0% would return $95 for every $100 wagered, compared to $96 for the 96.0% version. That is a $1 difference per $100, which adds up over time.
The maximum win is 26,000x your stake. If you bet $1, that is $26,000. At the minimum bet of $0.20, the max win would be $5,200.
Because the RTP can vary between operators, it is worth checking the game's info panel at the casino you play at to see which version is installed. That panel usually shows the RTP and other game rules.
Demo mode vs real money
The demo version of Bonanza Megaways uses play credits but otherwise works exactly like the real-money game, including the same RTP and volatility. It is useful for getting a feel for the game's high volatility—expect long dry spells punctuated by occasional larger wins. You can test how different bet sizes affect your session length and see how often the free spins trigger (which requires 4 scatters). When you switch to real AUD, the stakes are real, so your bankroll limits matter more.

Bonanza Megaways is a solid choice for players who enjoy high volatility and the Megaways format. The unlimited multiplier in free spins is a standout feature. However, the lack of a bonus buy means you might wait a while for the feature. It suits players with a bankroll that can handle swings; those who prefer frequent smaller wins may want to look elsewhere.
