Slot Details for Bonanza Megaways

Bonanza Megaways uses the Megaways engine where each reel shows between two and seven symbols per spin. The Extra Reel rides above reels two to five on mining carts, adding one symbol to each and raising the ways. With the minimum set-up you spin on 324 ways, and with seven symbols on all six reels you see the full 117,649. Wins form on successive reels from the leftmost reel and matching symbols can land in any position.

Stakes run from 20p to £20 per spin. I adjust with the arrows in the Stake box and keep it steady for long sessions. Non-UK versions allow Autoplay up to 100 spins with loss and single win limits. Variance sits in the medium to high bracket and the hit frequency is 37.47%. Expect most base game hits to be smaller, with the heavier payouts showing up in the feature thanks to the growing multiplier.

Theme, Audio + Symbols in Bonanza Megaways

Set at the entrance to a mine on lush green hills, Bonanza Megaways runs with a toe-tapping hillbilly soundtrack, a waterfall and a wooden hut. Reels show low-value 9, 10, J, Q, K and A, then green emerald, blue sapphire and red ruby gems, plus the top diamond. Payouts for six-of-a-kind run from 0.8x on the 9 up to 1.75x on A and K, 2x on green or blue, 7.5x on ruby and 50x on the diamond.

Dynamite Sticks Wilds land only on the Extra Reel above reels two to five and substitute to complete wins. G, O, L and D scatters trigger the feature, with a +5 scatter on the trigger spin adding five extra spins. During Free Spins, Gold Bullion scatters appear in the carts and award more spins. Three bullion symbols grant five more and four grant ten, letting the bonus stretch when the tumbles keep landing.

Bonus Features in Bonanza Megaways

Reactions sit at the heart of Bonanza Megaways. Any winning combination explodes, the symbols drop, and new ones fall in to fill the gaps. If the new set creates another win, the process repeats. It only stops when no fresh win appears. In many reviews this feature is called Cascading Reels or the Avalanche. In play it feels brisk and can string together tidy sequences that grow your return from a single paid spin.

Free Spins trigger when the gold G, O, L and D scatters land together. You start with 12 spins and each extra scatter on the trigger adds five more. I've had entries begin with 17 or even 22 spins when a +5 symbol shows. The Unlimited Win Multiplier starts at 1x and climbs by one after every Reaction during the bonus. There is no cap, so sustained cascades can stack the value and tilt the balance.

Extra spins come from the Gold Bullion scatter that only appears in the carts during the feature. Three bullion symbols award five extra spins and four award ten. I aim to keep the tumbles flowing early, as the multiplier rising with each Reaction is the route to the 26,000x top end. Big hits cluster here, and the base game feels more measured, so I pace my stake and wait for the bonus to fire.

RTP and Volatility in Bonanza Megaways

Bonanza Megaways runs at a flat 96% RTP across UK sites. Variance leans medium to high, so streaks can stretch and dead spins will show up. The hit rate sits at 37.47% and most line wins are on the lighter side in the base game. I keep stakes modest to ride the swings and save the push for Free Spins, where the unlimited multiplier can turn a tidy start into something that matters.

Expert Verdict on Bonanza Megaways

Bonanza Megaways put the mechanic on the map and still feels fresh. The mining set-up, carts on the Extra Reel, and that jaunty soundtrack give it proper charm, while Reactions keep the pace. I rate the game for its free spins punch and the improved 26,000x max win. The bonus can be stubborn at times, yet when the multiplier takes off it gets lively fast. It is a regular in my rotation for a reason.
