Bonanza Megapays Review

Strike Gold in Big Time Gaming’s Bonanza Megapays™ Mining Adventure

Bonanza Megapays™ takes one of the most iconic slots ever produced by Big Time Gaming and supercharges it with a brand-new progressive jackpot engine. As the very first title in BTG’s groundbreaking Megapays™ series, Bonanza Megapays returns players to the dusty gold mine, gem-laden carts, and explosive cascades that made the original Bonanza Megaways™ a global phenomenon, while layering four shared-liquidity progressive jackpots on top of the familiar 117,649 ways to win.

The moment the reels load, the heritage is unmistakable. Six glittering reels sit framed by craggy rock faces, mining carts trundle across the top of the grid, and the rhythmic clink of pickaxes underscores every spin. This is the gold-prospecting world that fans have spent years exploring, faithfully recreated and given new purpose. Yet beneath that comforting familiarity beats an entirely new heart: the Megapays jackpot system, which can ignite on any spin, at any bet level, transforming an ordinary session into a life-changing one.

What sets Bonanza Megapays apart from the original is the promise that every single spin carries the chance of a progressive prize. Where the classic Bonanza chased a 12,000x base maximum, Bonanza Megapays climbs to a base-game ceiling of 17,926x your stake and then opens the door to four escalating jackpot tiers — Mini, Midi, Major, and Mega — whose combined potential pushes total win exposure beyond an astonishing 3,000,000x. The Mega jackpot alone seeds at €300,000, a number that dwarfs the headline figures of most Megaways slots.

The core mechanics remain instantly recognisable to Bonanza veterans. The Megaways™ engine delivers up to 117,649 ways to win, cascading Reactions clear winning symbols to make room for fresh ones, and the carts feature running above reels 2-5 injects extra symbols and Dynamite Wilds into combinations. Spelling G-O-L-D with scatter symbols unlocks Free Spins, where an unlimited progressive multiplier climbs with every consecutive Reaction — the very mechanic that made the original such a high-ceiling thriller.

With a 96.40% RTP, high volatility, a bet range of £0.20 to £30, and the eternal possibility of a jackpot drop, Bonanza Megapays is both a nostalgic homecoming and a genuine evolution. Whether you are a long-time prospector returning to the mine or a newcomer drawn by the jackpot fireworks, this review digs into every seam of the game so you know exactly what you are chasing.

The Megaways™ Mechanic: 117,649 Ways to Strike It Rich

Understanding Megaways™ in Bonanza Megapays

At its foundation, Bonanza Megapays runs on Big Time Gaming’s legendary Megaways™ engine — the very system BTG invented and the same one that powered the original Bonanza to fame. Rather than fixed paylines, Megaways™ generates a fresh number of ways to win on every spin, creating constantly shifting possibilities as the reels load.

How Megaways™ Works Here:

• 6 vertical reels, each displaying between 2 and 7 symbols per spin.
• Carts above reels 2-5 add an extra horizontal layer of symbols to the calculation.
• Ways to win are calculated by multiplying the number of symbols on each reel together.
• Maximum ways: when every reel and cart is full, you reach the headline 117,649 ways to win.
• Minimum ways: when reels show their smallest configuration, ways shrink to the dozens.

Win Formation Rules:

• Wins are paid for matching symbols on adjacent reels from left to right, starting from reel 1.
• Symbol size is irrelevant — a single small symbol counts the same as a tall stacked one.
• Only consecutive reels count toward a win; a gap breaks the chain.
• Multiple winning combinations can land simultaneously and all pay out together.
• Every payout is a multiple of your total stake, not a per-line amount.

Why Megaways™ Matters in Bonanza Megapays:

The dynamic nature of the engine is central to the experience. Some spins arrive with sparse reels and only a handful of ways, while others fill out to deliver tens of thousands of winning possibilities. Combined with the carts adding extra symbols and the cascading Reactions clearing space for fresh drops, the Megaways™ system keeps every spin visually distinct and full of anticipation. It is also the perfect canvas for the Free Spins multiplier to build upon, since each Reaction can both pay out and push the multiplier higher.

The Megapays Jackpot System: Four Progressive Prizes

What Makes Megapays Different

The Megapays™ mechanic is the headline innovation and the reason Bonanza Megapays exists as a distinct title. While the base game plays like a polished Megaways slot, every spin you make also feeds and qualifies for a shared progressive jackpot network. This is BTG’s de-risked, multi-tier jackpot framework, and Bonanza Megapays was the very first game to use it.

A portion of the game’s overall return — 9.44% of the total RTP — is dedicated to the jackpot pool. Each bet contributes a small slice to each of the four tiers, so the prizes grow over time across every player spinning the game. Crucially, the jackpots are de-risked, meaning the displayed amounts are funded by the network rather than gambled directly from your own stake, and any tier can be won on any bet size.

The Four Jackpot Tiers

Bonanza Megapays offers four escalating progressive jackpots, each with its own seed value and trigger threshold:

The Mega jackpot is the prize that defines the game’s headline potential, with its progressive value capable of pushing total win exposure beyond 3,000,000x your stake — a figure no base-game feature could ever reach.

How the Jackpot Triggers

The beauty of the Megapays system is that it can ignite on any spin, at any moment, regardless of bet size. Here is how a jackpot round unfolds:

1. Random Activation: At the start of an eligible spin, the Megapays feature can trigger entirely at random — there is no symbol you need to chase in advance.
2. Symbol Selection: When the feature fires, one symbol is chosen at random to become the Megapays symbol for that round.
3. The Megapays Grid: The game transitions to a fixed 6×7 grid (42 positions) dedicated to the jackpot draw.
4. Symbol Collection: Megapays symbols land across the grid, and you collect every matching symbol that appears.
5. Tier Determination: The total number of Megapays symbols collected decides which jackpot you win — the more symbols, the higher the tier.
6. Instant Award: The corresponding progressive amount is paid immediately and the relevant jackpot resets to its seed value.

Worked Example:

• You are spinning at a £1.00 stake.
• The Megapays feature triggers at random and a gold-bar symbol is chosen.
• The 6×7 grid fills and you collect 9 matching symbols.
• Nine symbols falls into the 8-11 band, awarding the Midi jackpot (seeded at €1,500 and likely higher after progression).

Why the Bet-Agnostic Design Matters:

Because the jackpots are won independently of bet size, a player wagering the £0.20 minimum has the same chance of triggering and winning the Mega as someone betting £30. This is a deliberate, player-friendly design choice that keeps the dream alive for low-stakes prospectors and is a hallmark of the de-risked Megapays framework.

Cascading Reactions: Chains of Consecutive Wins

How Reactions Work

Like every great BTG title, Bonanza Megapays uses cascading Reactions (BTG’s term for tumbling reels) to multiply the value of a single spin.

1. Winning symbols that form part of a combination are highlighted and removed from the grid.
2. New symbols drop down from above to fill the empty positions, and fresh symbols enter from the carts.
3. Any new wins formed by the dropped symbols pay out instantly.
4. The chain continues until a Reaction produces no further wins.

Why Reactions Are Crucial:

• A single spin can produce a string of consecutive wins, dramatically increasing its total value.
• Reactions are the engine behind the Free Spins multiplier, which climbs with every successive cascade.
• They keep the action flowing and maintain on-screen excitement even on smaller initial hits.
• Combined with the carts dropping in extra symbols, Reactions can extend far longer than a standard tumble.

In the base game, Reactions deliver welcome win-boosting chains. In Free Spins, however, they become the central strategic mechanic, as every cascade pushes the multiplier higher and compounds your winnings.

The Carts Feature: Extra Symbols and Dynamite Wilds

A defining visual signature of the Bonanza series is the carts that run along the top of the grid. In Bonanza Megapays, dynamic cart positions sit above reels 2, 3, 4, and 5, and they play a genuine mechanical role rather than being mere decoration.

How the Carts Work:

• The carts deliver additional symbols into the relevant reels, contributing to win calculations and the overall ways count.
• They are the home of the Dynamite Wild symbol, which substitutes for paying symbols to help complete winning combinations.
• As Reactions clear winning symbols, the carts feed fresh symbols into the grid, helping cascades chain together.
• Their presence is what allows the game to reach the full 117,649 ways when everything aligns.

The Dynamite Wilds are particularly valuable because they appear from the carts and can bridge gaps in combinations, turning near-misses into payouts and extending Reaction chains that might otherwise stall.

GOLD Free Spins & The Unlimited Multiplier

Spelling G-O-L-D

The classic Bonanza Free Spins trigger returns intact. Instead of generic scatters, Bonanza Megapays uses lettered scatter symbols that spell the word GOLD.

Trigger Requirements:

• Land the G, O, L, and D scatter symbols to spell GOLD and unlock the bonus.
• The base award is 12 Free Spins.
• Collecting additional scatters during the round can retrigger and extend your spins.

The Unlimited Progressive Multiplier

The headline attraction of the Free Spins round — and the mechanic responsible for the original Bonanza’s legendary big wins — is the unlimited progressive multiplier.

How the Multiplier Works:

1. The win multiplier starts at x1 at the beginning of the Free Spins round.
2. Every consecutive Reaction during a single free spin increases the multiplier by +1.
3. Crucially, the multiplier does not reset between free spins — it carries forward for the entire bonus round.
4. There is no upper cap, so a sustained run of Reactions can push the multiplier to enormous heights.

Worked Example:

• You are deep into a Free Spins round with the multiplier sitting at x18.
• A spin produces a winning Reaction worth 40x stake before the multiplier.
• The win is multiplied: 40x × 18 = 720x your stake.
• That same Reaction then pushes the multiplier to x19 for the next win.

This compounding, uncapped multiplier is what gives Bonanza Megapays its high-volatility profile and its genuine big-win potential. Long Free Spins rounds with frequent Reactions are where the base game’s 17,926x ceiling comes within reach.

Symbols & Paytable

Bonanza Megapays embraces its mining theme with a symbol set split between low-value royals and high-value gems and rocks.

Low-Paying Symbols:

• The card royals — 9, 10, J, Q, K, and A — make up the low end of the paytable. They land frequently and pay modest amounts, primarily useful for keeping Reactions alive.

High-Paying Symbols:

• A trio of coloured rock and stone symbols form the mid-to-high tier, paying roughly 2x to 7.5x for a full six-of-a-kind combination depending on the symbol.
• The premium diamond / gem symbol is the most valuable, and it pays even for just two of a kind, rewarding up to around 50x for a full six-symbol line.

Special Symbols:

• GOLD Scatters: The lettered G-O-L-D symbols that trigger the Free Spins feature.
• Dynamite Wild: Appears from the carts and substitutes for paying symbols to complete combinations.
• Megapays Symbol: A symbol selected at random when the jackpot feature triggers, collected on the dedicated grid to determine your jackpot tier.

Reading the Paytable:

• All wins pay left to right on adjacent reels, starting from reel 1.
• Payouts are quoted as multiples of your total stake.
• The diamond’s two-of-a-kind pay is a generous touch that helps keep Reactions chaining.
• Because the high pays are relatively modest per combination, the game’s big wins come from stacking multiple combinations, long Reaction chains, and the Free Spins multiplier — not from any single landing.

How to Win: Strategy & Tips

Bonanza Megapays is a high-volatility slot with a jackpot overlay, so a disciplined approach matters more here than in a gentler game.

Bankroll Management

• Size your stake for endurance. High volatility means extended dry spells. A common guideline is to keep your stake at roughly 1% or less of your session bankroll so you can absorb the swings.
• Use the wide bet range wisely. With bets from £0.20 to £30, there is plenty of room to scale. Remember that jackpot eligibility is identical at every stake, so betting higher does not improve your jackpot odds — it only changes the size of base-game wins.
• Set loss and win limits before you spin and walk away when you hit them. The lure of “the next spin could be the jackpot” is precisely what high volatility preys upon.

Base Game Approach

• Treat the base game as the build-up. Most of your spins will tick over with small Reaction wins while you wait for either the GOLD trigger or a random Megapays activation.
• Value the carts. The Dynamite Wilds from the carts above reels 2-5 are key to extending Reactions and completing combinations, so spins where the carts are active tend to be more productive.
• Stay patient for Free Spins. Spelling GOLD is the primary route to the game’s biggest base-game wins, since only there does the unlimited multiplier come into play.

Bonus & Jackpot Strategy

• There is no strategy that influences the jackpot. The Megapays feature is fully random and bet-agnostic — no skill, symbol-chasing, or bet-sizing changes your odds. Simply playing keeps you eligible.
• In Free Spins, longevity is everything. Because the multiplier never resets and has no cap, the value of a bonus round is decided by how many consecutive Reactions you can string together. Retriggers that extend your spin count are extremely valuable.
• Manage expectations on the 3,000,000x figure. That number is jackpot-driven and exceptionally rare. The realistic big-win target from regular play is a strong Free Spins round climbing toward the 17,926x base ceiling.

Gameplay Experience

Visual Presentation

Bonanza Megapays preserves the warm, earthy aesthetic that fans adore. The reels are set inside a rocky mine, with the iconic carts rolling across the top of the grid and a backdrop of rolling green hills and blue sky beyond the rock face. Symbols are crisp and colourful — gleaming gems, chunky coloured stones, and clean card royals — all rendered in Big Time Gaming’s polished house style.

The Megapays jackpot transition is a genuine highlight. When the feature fires, the game shifts to a dedicated grid with its own dramatic presentation, the four jackpot values displayed prominently as symbols rain down. It is a clear, satisfying piece of theatre that makes the jackpot moment feel special and distinct from regular play.

Audio Design

The soundtrack leans into the mining and Wild West atmosphere with rhythmic, upbeat instrumentation that intensifies as Reactions chain together. Each cascade is punctuated by the clink of stones and the satisfying crunch of symbols clearing, and the audio swells noticeably during Free Spins as the multiplier climbs — an effective way of building tension during the game’s most lucrative moments.

Mobile Experience

Bonanza Megapays is built with Big Time Gaming’s modern HTML5 framework and is fully optimised for mobile and tablet play.

• Responsive layout: The 6-reel grid and the carts scale cleanly to portrait and landscape orientations without losing clarity.
• Touch controls: Spin, bet adjustment, autoplay, and the paytable are all accessible through large, finger-friendly buttons.
• Performance: Cascading Reactions and the jackpot grid transition run smoothly on modern smartphones, with no loss of fidelity in the animations.
• Readability: Despite the busy mining backdrop, symbols and the jackpot meters remain legible on smaller screens.

Whether you are spinning on a desktop, an iOS device, or an Android phone, the experience is consistent, and crucially, jackpot eligibility is identical across all platforms — a mobile spin can win the Mega just as easily as a desktop one.

Frequently Asked Questions

What is the RTP of Bonanza Megapays?

Bonanza Megapays has an RTP of 96.40%, which is in the average-to-good range for a jackpot-equipped slot. Of the overall return, 9.44% is allocated to the four progressive Megapays jackpots, with the remainder driving base-game and Free Spins payouts.

What is the maximum win on Bonanza Megapays?

The base-game maximum win is 17,926x your stake. However, the Megapays jackpot system lifts the total win potential beyond 3,000,000x, thanks to the progressive Mega jackpot that seeds at €300,000 and grows over time.

How do the Megapays jackpots work?

There are four progressive jackpots — Mini, Midi, Major, and Mega. The feature can trigger at random on any spin. When it does, a symbol is chosen at random and you collect matching symbols on a dedicated 6×7 grid. The number you collect determines the tier: 4-7 symbols wins the Mini, 8-11 the Midi, 12-14 the Major, and 15+ the Mega.

Can I win the jackpot on any bet size?

Yes. The Megapays jackpots are de-risked and bet-agnostic, meaning any jackpot can be won on any stake from £0.20 to £30. Betting more does not increase your chance of triggering or winning a jackpot — it only changes the size of your regular base-game wins.

Does Bonanza Megapays have a Bonus Buy?

No. Unlike some newer Big Time Gaming titles, Bonanza Megapays does not offer a Bonus Buy option. You must trigger the Free Spins organically by spelling G-O-L-D with the scatter symbols.

How do you trigger Free Spins in Bonanza Megapays?

You trigger Free Spins by landing the lettered scatter symbols that spell G-O-L-D. Doing so awards 12 Free Spins, during which an unlimited progressive multiplier increases by +1 with every consecutive Reaction and never resets for the duration of the round.

Is Bonanza Megapays high volatility?

Yes. Bonanza Megapays is a high-volatility slot (rated around 4 out of 5). Wins arrive less frequently but can be substantial, particularly during a long Free Spins round with a climbing multiplier or when a jackpot drops.

Who makes Bonanza Megapays?

Bonanza Megapays is developed by Big Time Gaming (BTG), the studio that invented the Megaways™ mechanic and created the original Bonanza Megaways™. Bonanza Megapays is the first title in BTG’s Megapays™ progressive jackpot series.

Verdict

Bonanza Megapays is a confident, well-judged evolution of one of the most beloved slots ever made. By grafting a four-tier progressive jackpot system onto the proven Bonanza Megaways™ formula, Big Time Gaming has created a game that delivers both the comfort of nostalgia and the thrill of a genuine jackpot chase. The familiar mining theme, cascading Reactions, carts, and unlimited Free Spins multiplier are all present and correct, and the addition of the bet-agnostic Megapays jackpots — with a Mega prize seeding at €300,000 — gives every single spin a tantalising extra layer of possibility.

It is not a flawless package. The absence of a Bonus Buy will disappoint players who like to fast-track to Free Spins, the high volatility demands a serious bankroll and a patient temperament, and the eye-catching 3,000,000x headline is realistically a jackpot fantasy rather than an everyday target. The base-game ceiling of 17,926x, while respectable, is also more modest than some of BTG’s later releases.

Still, for what it sets out to do, Bonanza Megapays succeeds emphatically. The 96.40% RTP is fair for a jackpot slot, the low £0.20 entry point keeps the Mega dream open to every player, and the core gameplay remains as moreish as ever. As the trailblazer for the entire Megapays series, it carries genuine historical significance, and it remains one of the most satisfying ways to combine classic Megaways action with progressive jackpot excitement.

Our Rating: 4.3 / 5 — A nostalgic, jackpot-charged reimagining of a classic that earns its place in any prospector’s rotation. The four progressive tiers and the timeless Bonanza gameplay outweigh the lack of a Bonus Buy and the punishing variance. Strap on your hard hat and head back to the mine — the next spin really could change everything.
