Bonanza Megaways online slot review
Bonanza Megaways is a distinctive 6-reel slot with cascading wins powered by BTG’s trademark Megaways mechanic. It offers 117,649 ways to win, extra symbols above the reels, a random symbol count on every spin, cascading reels, and free spins.
Theme and Storyline
Set in a mine, the slot invites players to put the available tools and equipment to work and dig through a rock quarry in pursuit of explosive wins.
Graphics, sound and animation
Bonanza Megaways pairs crisp visuals with lively reel and bonus-round animation. BTG has a reputation for dynamic animated 3D slots, and the reviewer finds that the software designer 100% delivers on that standard here.
The mining setting is brought to life with detailed animation, while the reels stay in motion: symbols burst, coins fly up to tally your winnings, dynamite fuses sparkle and bonus features play out on screen.
The soundtrack matches the visuals, blending a western-style cowboy tune with explosive effects as symbols burst and dynamite goes off.
Top Casinos to Play Bonanza Megaways:
Gameplay
Instead of conventional paylines, Bonanza Megaways uses Megaways wins. A winning combination must start on reel 1 and run across consecutive reels from left to right. Matching symbols on adjacent reels count, wherever they land.
The purple gem is the highest-paying symbol, awarding wins for combinations of 2, 3, 4, 5 or 6. A combination of 6 pays 50 times the spin bet. Red, blue and green gems, as well as Ace, King, Queen, Jack, 10 and 9 symbols, pay for combinations of 3, 4, 5 or 6 matching symbols.
The number of symbols on each reel is randomized on every spin. One spin might show 4 symbols on reel 1, 6 on reel 2 and 4 on reel 3; another might show 6 on reel 1, 2 on reel 2 and 3 on reel 3. Above the reels, 4 extra bonus symbols sit over reels 2, 3, 4 and 5, adding even more Megaways.
The format is different from a traditional slot, but the controls are simple. Set your total stake for the spin, press spin and let the slot take care of the rest.
To use auto spins, open the menu and select between 5 and 100 spins. You can also choose a loss limit or a single-win limit; reaching either limit ends the auto spins. The menu also includes sound settings, pays (the paytable) and a help guide.
Bonuses and free spins
The bonus features are among Bonanza Megaways’ biggest draws.
Cascading reels, which BTG calls reactions, kick off the feature sequence. When symbols form a winning combination, they explode and new symbols drop into the empty spaces. Any new wins are paid, then those symbols explode too. Cascades continue until no more wins form.
The train cart above the reels adds symbols to reels 2, 3, 4 and 5, increasing the number of available ways to win.
Scatter symbols G, O, L and D trigger free spins: when 4 land across the reels to spell ‘GOLD’, they award 12 free spins. Each additional scatter showing 5 that lands while free spins are in progress adds 5 more spins. Retriggers are also possible: 3 scatters award 5 extra free spins, and 4 scatters award 10 extra free spins.
Cascading wins continue during free spins, and each new combination receives a multiplier. The multiplier increases by 1 each time another symbol combination forms, with no stated limit.
The wild dynamite symbol can also help create additional wins. It appears through the train feature and on the reels.
Bet sizes, RTP and variance
Bonanza Megaways has a minimum stake of 0.20 per spin and a maximum of 20.00 per spin. Although it offers many symbol combinations, it is classified as a high-variance game. Large wins depend on landing plenty of feature bonuses, though wilds and the extra reel can still deliver smaller wins. The stated RTP is 96%.
Conclusion
This slot pairs polished graphics and animation with engaging play. Its standout features include 6 reels and 117,649 Megaways to win. Players used to payline-free games with 243 ways or 1,024 ways to win may find Bonanza Megaways offers a much broader range. BTG also brings together cascading reels, multiplier free spins and wilds.
