Bonanza Megaways (Big Time Gaming) RTP review: 96%
The slot that licensed an industry
Every Megaways game you have ever played descends from this one. Big Time Gaming built Bonanza in 2016 as the first outing for its randomised-reel engine — six reels, each showing between two and seven symbols per spin, so the number of ways to win changes constantly up to a maximum of 117,649. The idea was strong enough that BTG turned the engine itself into a product, licensing "Megaways" to dozens of rival studios; the hundreds of Megaways titles now in circulation all pay a royalty to the mechanic this gold-mining game introduced. That history matters for evaluating it today: Bonanza is the reference implementation, leaner than most of its descendants — no bonus-buy, no ante bet, no jackpot bolt-ons — and its maths reflect that restraint.
Reactions, GOLD scatters and the unlimited multiplier
Wins trigger reactions: winning symbols are removed and replacements fall in, continuing as long as new wins form. The bonus is famously spelled out — scatters carrying the letters G, O, L and D must land to start free spins — and once inside, the game reveals its defining feature: a win multiplier that starts at 1x and increases by 1 with every reaction, with no ceiling and no reset for the duration of the round. A long chain of cascading wins late in a good bonus is therefore worth vastly more than the same chain early on, and the advertised 26,000x cap is essentially a statement about how far that compounding can run. Retrigger and trigger specifics are in the paytable — worth a look, since the mechanic's simplicity hides a few fine rules.
Average RTP, above-average honesty
At exactly 96%, Bonanza sits on the market's centre line — a 4% theoretical edge over the long run, neither generous nor mean. Two things make that figure more useful than most: it is fixed at every licensed casino, and it is not diluted by purchasable features with separate maths. The med-high volatility rating (4/5) understates how bonus-dependent the experience is; base-game reactions churn pleasantly but the unlimited multiplier is where the game's entire reputation — and most of its return — lives. Budget accordingly: the G-O-L-D hunt can run long.
Practical notes before mining
- No build anxiety. Uniquely useful: 96% is the number everywhere, so there's nothing to verify beyond the game loading at all.
- The multiplier never resets mid-bonus. Reaction chains compound — the whole value proposition is bonus depth.
- No buy, no shortcuts. Later Megaways titles added purchase options; the original makes you land the letters.
- 20 max bet. A lower stake ceiling than much of the genre it spawned.
Strengths & weaknesses
Strengths
- The original Megaways — historically important and still mechanically clean
- Unlimited, non-resetting free-spins multiplier with a 26,000x cap
- Fixed 96% at any stake, any casino
Weaknesses
- 96% is strictly average — the fame is in the mechanic, not the return
- Heavily bonus-reliant; base reactions rarely amount to much
- No feature-buy for players who want the multiplier without the wait
How Bonanza Megaways compares
The first Megaways game measured against the BTG titles that followed it.
| Slot | Provider | RTP | Volatility | Max win |
|---|---|---|---|---|
| Bonanza Megaways (this slot) | Big Time Gaming | 96% | Med-High | 26,000x |
| White Rabbit Megaways | Big Time Gaming | 97.72% | High | 13,000x |
| Extra Chilli | Big Time Gaming | 96.82% | High | 20,000x |
| Danger High Voltage | Big Time Gaming | 95.67% | High | 15,746x |
| Lil Devil | Big Time Gaming | 96.43% | Very High | 40,960x |
The founder posts the table's plainest figure — and its historical weight. Every row beneath exists because this one worked: White Rabbit took the RTP crown, Extra Chilli the interactivity, the branded pair the ceilings. As a pure number, 96% wins nothing here except reliability.
Our verdict on Bonanza Megaways
Skip if: you're optimising for RTP; the engine's descendants and rivals frequently price themselves higher
Bonanza remains the best answer to the question "what is Megaways actually about?" — variable ways, cascading reactions, and one unlimited multiplier that makes bonus length the only currency that counts. As a piece of design it has aged remarkably little; as a value proposition it is deliberately middle-of-the-road, and BTG's own catalogue undercuts it (Extra Chilli runs to 96.82% on the right build, White Rabbit to 97.72%). Play it for the original article and the G-O-L-D ritual; look to its siblings when the number on the info screen is what matters most to you.
