By the time Reel Kingdom bolted the Megaways engine onto its runaway fishing franchise, we had already logged hundreds of spins across the original Big Bass series. This review sets out to answer the only question that matters to a discerning player: does the added ways-to-win maths genuinely improve the game, or does it simply dress up a familiar formula? Here is the measured breakdown.

Big Bass Bonanza Megaways is the Megaways interpretation of one of the most successful slot brands of the modern era. The base concept is unchanged: a cheerful angler, a lakeside setting, and money-symbol fish that carry cash values. What differs here is the engine underneath. Rather than a fixed 5×3 layout, the reels expand and contract each spin, delivering a variable number of symbols and, at their peak, 200,704 ways to win. A tumbling mechanic replaces winning symbols with new ones, allowing consecutive hits from a single paid spin.
In practical terms, this is a high-volatility release. Sessions will run through quiet stretches, and the meaningful money is concentrated in the free spins round. That profile is consistent across the Big Bass catalogue, but the Megaways maths widens the distribution — bigger ceiling, longer dry spells.
Setup is deliberately uncomplicated. Choose a stake within the operator’s band, then spin. Wins form when matching symbols land on adjacent reels from the leftmost position, regardless of row, in standard Megaways fashion. Every win triggers a tumble, and tumbles continue until no further combinations appear.
Two optional controls shape the experience. An Ante Bet raises your stake to improve the frequency of scatters and thus quicker access to free spins. Separately, a Buy Feature lets you purchase direct entry to the bonus for a fixed multiple of your stake. Both are legitimate tools, but they alter the risk equation — the Buy Feature in particular concentrates variance sharply. Confirm the exact cost and any RTP change in the paytable before committing.
The heart of the game is the Free Spins round, entered by landing the required number of scatters. Inside it, the wild fisherman does the heavy lifting: whenever he appears alongside money symbols, he collects their combined values. The defining twist is the multiplier that climbs as fishermen are collected during the feature — after set thresholds it rises and applies to every subsequent collect, with additional spins awarded along the way. This is where the 5,000x ceiling becomes reachable, and it is the single most important reason to reach the bonus rather than grind the base game.
Presentation is polished and instantly recognisable. The lake-and-reeds backdrop, the relaxed fisherman, and the upbeat soundtrack are lifted faithfully from the franchise, and the animation holds up well when reels expand to their full Megaways height. It is not a technical showcase, nor does it try to be; the artwork prioritises clarity and mood over spectacle, which suits the game’s broad audience.
A carefully executed Megaways conversion that respects what made the original work while raising the ceiling for those willing to weather the variance. It will not convert players who dislike bonus-dependent slots, but as a considered addition to a strong franchise it earns its place. Check the RTP your operator serves before you sit down.
The title is widely distributed, so availability is rarely the issue — RTP configuration and withdrawal reliability are. The operators below are ones we rate on those grounds.
The default return to player is 95.03%. Because Reel Kingdom supplies alternate RTP configurations, some casinos run lower versions — always confirm the figure in the game’s info screen.
It is a high-volatility slot. Expect quiet base-game periods, with the substantial returns concentrated in the free spins feature.
The capped maximum win is 5,000x your total stake, most realistically achieved through the multiplier stacking in free spins.
Yes, where regulation permits, a Buy Feature grants direct entry to free spins for a set multiple of your stake. It raises variance considerably, so use it deliberately.
Thanks to the Megaways engine, the grid offers up to 200,704 ways to win, varying spin to spin as the reels change height.
