Bonanza Megaways online slot review
Bonanza Megaways is a distinctive 6-reel slot featuring reacting wins through BTG’s trademark Megaways mechanic. It offers 117,649 ways to win through extra symbols above the reels, a random symbol count on every reel spin, cascading reels and free spins.
Theme and storyline
With mining as its setting, the slot asks players to put the available tools and equipment to work, digging through a rock quarry in pursuit of explosive wins.
Graphics, sound and animation
Bonanza Megaways presents polished imagery and energetic animation across the reels and bonus game. BTG is known for fast-moving animated 3D slots, and in the review’s assessment, the software designer 100% lives up to that reputation in this title.
The mining backdrop features high-performance animation, while the reels keep the action moving: symbols burst, coins spray into the air to count your cash after a win, dynamite fuses sparkle and feature bonuses unfold in the scenes.
The audio matches the visual quality, pairing a western-style cowboy melody with explosive effects as symbols burst and the dynamite detonates.
Top Casinos to Play Bonanza Megaways:
Gameplay
Rather than traditional pay lines, Bonanza Megaways uses Megaways wins. A winning combination must begin on reel 1 and continue across consecutive reels from left to right. If the same symbol appears on the adjacent reel, it qualifies regardless of its position.
The purple gem is the top-paying symbol, with wins for combinations of 2, 3, 4, 5 or 6. Landing 6 multiplies the spin bet by 50. Red, blue and green gems, along with Ace, King, Queen, Jack, 10 and 9 symbols, pay when a combination contains 3, 4, 5 or 6 matching symbols.
Each reel receives a random number of symbols on every spin. One result may show 4 symbols on reel 1, 6 on reel 2 and 4 on reel 3, while another may show 6 on reel 1, 2 on reel 2 and 3 on reel 3. Above the reels, an extra 4 bonus symbols sit over reels 2, 3, 4 and 5, creating still more Megaways.
Although the format differs from a conventional slot, the controls are straightforward. Choose the total stake for the spin and press spin; the slot handles the rest.
For auto spins, open the menu and choose between 5 and 100 automatic spins. You can also set a loss limit or single-win limit; reaching either one stops the auto spins. Other menu options cover sound, pays (the paytable) and the help guide.
Bonuses and free spins
The review describes the bonus features in Bonanza Megaways as a major attraction.
The feature sequence begins with cascading reels, which BTG calls reactions. Whenever a symbol combination connects on the reels, the symbols involved explode and new symbols fall into the vacant spaces. Any resulting wins are paid, and those symbols then explode as well. Cascades continue until no further wins are created.
The train cart at the top of the reels adds symbols to reels 2, 3, 4 and 5, increasing the number of available ways to win.
Free spins are triggered by the scatter symbols G, O, L and D: when 4 appear across the reels to spell ‘GOLD’, the feature awards 12 free spins. Each additional scatter showing 5 that lands while free spins are triggered adds a further 5 free spins. Retriggers are available too: 3 scatters award 5 additional free spins, while 4 scatters award an extra 10 free spins.
During the free spins round, cascading wins remain active and each new combination receives a multiplier. That multiplier rises by 1 whenever another symbol combination forms, creating an unlimited multiplier feature.
Additional wins can also be connected with the wild dynamite symbol, which appears from 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. Despite its many symbol combinations, it is classed as a high-variance game. Big wins depend on landing plenty of feature bonuses, although wilds and the additional reel can still produce smaller wins. The stated RTP is 96%.
Conclusion
The review’s conclusion is that this slot combines polished graphics and animation with engaging gameplay. It highlights the distinctive 6-reels and 117,649 Megaways to win. Players familiar with payline-free games offering 243 ways or 1,024 ways to win may find Bonanza Megaways substantially broader. BTG also combines cascading reels, multiplier-equipped free spins and wilds.
