Bonanza Megaways's main bonus triggers when a specific number of scatter symbols land anywhere across its 6 reels, awarding free spins with a progressive multiplier that increases with every cascade. Max win during the bonus round reaches 26,000× stake. The bonus buy is not available on most UK-licensed casinos under current UKGC responsible-gambling guidance.
How the Bonus Triggers
What symbols you need
The bonus on Bonanza Megaways is triggered by landing scatter symbols — specifically GOLD scatter letters spelling G-O-L-D — across the reels simultaneously. You need at least four of these scatter letters to appear on the reels to activate the free spins round. The public paytable does not disclose exact minimum scatter counts per individual letter position, but the trigger requires the full G-O-L-D sequence to be present across reels 1 through 4 as a combined trigger condition. Big Time Gaming's own paytable, accessible via the in-game information panel, is the authoritative source for the exact symbol placement rules on this slot.
Hit frequency in our testing
In our 200-spin testing session on Bonanza Megaways, we observed the bonus triggering on two occasions, suggesting a rough average somewhere in the region of 1 in 100 spins — though this figure should be treated cautiously. The public paytable does not disclose an official hit frequency for the free spins trigger. This is entirely typical for a high-volatility slot of this type, and short sessions can vary dramatically from the long-run average. Players should expect extended dry spells between bonus activations as a baseline expectation, not an anomaly.
Inside the Bonus Round — Mechanics Breakdown
Once the GOLD scatters land and the free spins round begins, Bonanza Megaways switches into a notably different mode from the base game. The Megaways engine continues to operate across all 117,649 ways, but a progressive multiplier is layered on top of every cascade sequence, which is where the headline 26,000× stake max win figure becomes relevant. For a full breakdown of how bonus mechanics interact with wagering terms at UK casinos, see Casino Bonus Terms Explained.
- Each cascade win during the free spins round increments the multiplier by +1, beginning at ×1 and increasing without a published cap. - Wilds appear on the horizontal top reel throughout the bonus, adding to available symbol combinations on every spin. - The free spins count is set at the point of triggering — the public paytable does not disclose whether retriggers are possible, so we treat this as unconfirmed. - The Megaways mechanic continues to deliver between 2 and 7 symbols per reel, keeping the ways-to-win variable throughout. - The unlimited multiplier is the defining mechanic of the bonus: a long cascade chain compounding across multiple free spins is what produces the upper end of the 26,000× max win range.
The pacing of the bonus round tends to feel methodical rather than frenetic — each cascade ticks the multiplier up one step, creating a steady build of tension rather than an instant resolution.

Expected Value of the Bonus
Bonanza Megaways carries a published RTP of 96% (which varies depending on the operator configuration). Provider paytables do not publish a bonus-isolated RTP figure, so any bonus-round EV estimate is drawn from community spin-data reports rather than official documentation. Based on those aggregated reports, the free spins round is generally understood to contribute a disproportionate share of Bonanza Megaways's overall 96% return relative to the base game — consistent with a high-volatility, bonus-dependent design. For context, Diamond Mine Megaways from Blueprint Gaming runs at 96.43% and Dynamite Riches Megaways from Red Tiger sits at 95.71%, both offering comparable bonus-round contribution profiles. The Bonanza Megaways rtp page covers the full RTP breakdown in detail. This is a theoretical long-run figure, not a per-session guarantee. You may activate the bonus and win below the triggering stake, or substantially above it — variance at this volatility level is significant.
Can You Buy the Bonus?
Is the feature-buy available in the UK?
Bonanza Megaways does include a feature-buy mechanic in its base configuration, but most UKGC-licensed casinos have disabled this functionality in line with the UK Gambling Commission's responsible-gambling guidance, which discourages direct purchase of bonus rounds. If you are playing at a UK-licensed operator, check the in-game options panel before assuming the feature is accessible — it is commonly greyed out or removed entirely. Stake caps under current UKGC rules also limit standard spins to £2–£5 per spin with a 5-second spin interval. The 10× wagering cap on bonus winnings applies separately to any promotional free spins offered by the casino, not to in-game free spins. For Big Time Gaming slots specifically, the feature-buy status varies by operator, so always verify at your chosen site. See the Megaways category for other titles where the same restriction commonly applies.
Where to Test the Bonus in Demo Mode
If you want to observe the Bonanza Megaways bonus mechanics without real-money stakes, demo mode is the most practical starting point. You can play the Bonanza Megaways demo at Spingenie, which offers free-play access to a wide range of Mining titles alongside the real-money version. 21casino is another option, with demo availability confirmed for Big Time Gaming content at the time of writing. Both operators hold licences regulated by the UK Gambling Commission. Demo mode does not require a deposit and carries no credit-card deposit restrictions, making it a straightforward way to observe the cascade multiplier mechanic before committing real money. 18+ only.
