Bonanza Falls

Bonanza Falls Slot Review — Big Time Gaming

Bonanza Falls pairs Big Time Gaming’s Megaways engine with a jackpot layer, reaching a maximum win of 93,540 times the stake on a grid that generates up to 117,649 ways to win. Released on 1 December 2023, it carries forward the mining setting of the earlier Bonanza titles, adding a Reelset Changing bonus round on top of the familiar cascading-reel format.

Big Time Gaming was founded in 2011 and licenses its games through the UK Gambling Commission, the Malta Gaming Authority and the Alderney Gambling Control Commission, the regulators behind the studio’s wider Megaways catalogue that Bonanza Falls belongs to.

Core Gameplay Experience

Bonanza Falls runs on a six-reel Megaways grid, with the number of symbols on each reel changing from spin to spin to produce up to 117,649 ways to win. The Reelset Changing feature swaps in a different set of reels once the bonus round starts, which is why the reel count for this title is sometimes quoted as a range elsewhere — the base game itself deals from six reels throughout ordinary play.

The visual theme follows the mining setting of the earlier Bonanza titles: gold nuggets, dynamite (TNT) charges and gem symbols fall down a rock face, alongside woodland wildlife symbols. That gold-prospecting backdrop sits within the broader style of Money & Luxury themed slots on the site.

Features and Mechanics

The Multiway mechanic behind the 117,649 ways follows the same +1024-style expansion Big Time Gaming uses across its Megaways titles, with winning combinations read across adjacent reels in a Payline-style paytable despite the ways format. Falling symbols clear after every win through the Avalanche feature, also listed as Cascades: winning symbols vanish, new ones drop from above, and a resulting cascade can trigger further wins from the same initial spin without staking again.

Wilds substitute for regular symbols and can appear as Stacked wilds, occupying several positions on a single reel at once; Stacked symbols among the standard paying icons work the same way, raising the chance of a full match within one way. Multiplier Wilds and the Random Multiplier feature attach a multiplier to individual wins.

Scatter Symbols and the Bonus Symbols feature trigger the bonus round, called Megadozer Free Spins, which awards 12 free spins once triggered, per the provider’s own page for the game. Extra Free Spins can add further spins within that round, and the Free Spins Multiplier applies an additional multiplier to wins landed during the feature, separate from the base-game Random Multiplier.

Reelset Changing and Special reels mark the bonus round apart from the base game, swapping in a different reel set once Megadozer Free Spins begins rather than running the same six-reel grid throughout. A Bonus Buy option is available. The RTP Range feature reflects that Big Time Gaming publishes more than one RTP configuration for Bonanza Falls, covered below.

RTP, Volatility and Payout Model

The long-term return to players for Bonanza Falls stands at 96.51%. The provider’s own page for the game lists a second configuration running up to 96.52%, and which figure is live on a given spin depends on the casino running the game.

At high volatility with a 93,540x ceiling, payout value concentrates into a small number of larger hits rather than a steady trickle of smaller ones. The ceiling scales directly with the stake placed: at the minimum bet of 0.2, a full-ceiling hit equates to a payout of 18,708; at the maximum bet of 10.0, the same multiplier scales to 935,400.

Similar Slots — Comparison

All six titles in this comparison run on Big Time Gaming’s Megaways engine with cascading reels, and every one carries the same high-volatility rating, so volatility alone does not separate them. Bonanza Falls sits at 93,540x, the widest ceiling of the group, which spans from 4,130x up to that figure, and on a 1-unit stake that top prize equates to a 93,540-unit payout. Monopoly Megaways, Royal Mint Megaways and Gold Megaways post RTPs within a few cents of Bonanza Falls’s 96.51% but run Megaways and cascading reels without the jackpot layer, so weighing those three against Bonanza Falls really means weighing a jackpot mechanic against a non-jackpot one, not a volatility difference. Against Bonanza Megapays and Who Wants To Be A Millionaire Megaways, which both keep the jackpot layer, the gap is a small RTP difference — Bonanza Megapays trails by about $0.11 per $100 wagered and Who Wants To Be A Millionaire Megaways by about $0.27 per $100, in theory over the long run — while Who Wants To Be A Millionaire Megaways carries a lower ceiling at 50,000x against Bonanza Falls’s 93,540x.

How to Play Bonanza Falls Online

Bonanza Falls has a demo mode that runs the same math model without staking real money, a reasonable way to see how the Avalanche cascades and the Megadozer Free Spins round behave before deciding on a stake. The title sits in the Slots category alongside other Megaways releases built on the same engine. Big Time Gaming’s games are carried by 121 casinos as of 3 November 2026, including Mond Casino, Betroom24 and CasinoStars; checking a specific operator’s licensing and demo availability remains the more useful step than relying on the studio name by itself.

Verdict on Bonanza Falls

Bonanza Falls fits players who want a single high-ceiling target — a maximum of 93,540 times the stake — and who are comfortable with a high-volatility Megaways game where sessions can run empty for stretches before a cascade or the Megadozer round pays out. The game accommodates a bankroll designed for extended play at the lower end of the 0.2–10.0 stake range. Players who want frequent, moderate wins rather than a shot at a wide ceiling may want a lower-volatility mechanic altogether.
