Big Bass Bonanza Megaways Review - Demo, RTP & Casinos

How the six-reel set adds up to 46,656 ways

Megaways reels change height on every spin, and the number of ways to win is simply the symbol counts multiplied together. In this game the shape is uneven:

• Reels 1 and 6 show up to 6 symbols each.
• Reels 2, 3, 4 and 5 show up to 5 symbols each, plus one extra symbol from the horizontal top row.

That makes six positions as the most any reel can hold, and six reels of six gives 46,656 ways. Most spins land well below that, because the heights are drawn at random. The Megaways mechanic itself is licensed from Big Time Gaming, and the game footer names Reel Kingdom as the studio.

The top row has a second job. The Wild, a landing net, appears only there, above reels 2 to 5. It substitutes for every symbol except the Scatter and the Fisherman. You will never see a Wild on reel 1 or reel 6, so a win still has to start with a matching symbol on the first reel.

Wins tumble: winning symbols disappear, new ones fall in, and the process repeats until no new win appears. One paid spin can therefore produce several wins in a row. The game's rules also give it a Medium volatility label, the middle step on Pragmatic Play's three-step scale.

Big Bass Bonanza Megaways casinos in Canada

The list above shows Big Bass Bonanza Megaways casinos we cover whose published provider list includes Pragmatic Play. That is the honest starting point: the game ships through Pragmatic's catalogue, so a casino without Pragmatic Play will not have it. A provider list does not prove that this exact title is live, though, so search the lobby for "Megaways" before you deposit. The Big Bass series is large and the names are close.

Where you can legally play depends on your province:

• Ontario: online casinos registered with the AGCO that have an operating agreement with iGaming Ontario. Age 19+.
• Alberta: operators registered with the AGLC under an AiGC agreement, a market open since 13 July 2026. Age 18+.
• Elsewhere: each province runs its own site; age 19+, or 18+ in Manitoba and Quebec.

Offshore Big Bass Bonanza Megaways online casinos also accept Canadians, but no province licenses them, and provincial self-exclusion does not reach them. Compare options on our legal online casinos page, and see every Pragmatic Play brand we cover on the Pragmatic Play page. Bet limits can also differ from the demo's C$0.20 to C$240, because each casino sets its own.

The free spins round, one step at a time

Everything big in this game happens in free spins. Here is the order of events as the rules describe it:

1. Trigger. Three, four, five or six Scatters anywhere award 10, 15, 20 or 25 free spins.
2. Fish turn into money. During free spins, each fish carries a random value of 2x, 5x, 10x, 15x, 20x, 25x, 50x or 4,000x your total bet.
3. The Fisherman collects. The Fisherman lands only in free spins. Each one collects every money value on the screen.
4. Retriggers raise the multiplier. Every fourth Fisherman collected adds 10 more spins and lifts the multiplier for money collection and all wins to 2x, then 3x, then 10x. Three retriggers is the limit.
5. Dynamite and bazooka. If a free spin ends with only one or two Fishermen and no fish, dynamite can drop fish money symbols onto the reels, or a bazooka can change all non-Fisherman symbols.
6. The cap. The round ends as soon as its total reaches 4,000x the bet.

Two features stand out in this version: the dynamite and bazooka rescues for spins that would otherwise collect nothing, and the tumbling Megaways set underneath. Step 5 has a precise condition, so a free spin with three Fishermen, or with fish already showing, will not set it off.

What the base game pays between bonuses

Because the big money sits in free spins, it helps to know what the base game can return on its own. The paytable, read at a C$2.00 bet and converted to multiples of the stake, has three tiers:

• The fishing float is the only symbol that pays for two of a kind, and it tops the table at 50x the bet for six. Five pay 25x and four pay 10x.
• The fishing rod drops sharply to 7.5x for six, with the dragonfly and tackle box at 2x for six.
• The fish and the card ranks A, K, Q, J and 10 pay between 1.75x and 0.8x for six, and much less for three.

The fish deserves a note. In the base game it is just a regular paying symbol; it only carries a cash value once free spins begin. So a screen full of fish outside the bonus pays its line value and nothing more.

Tumbles soften this a little, since one spin can chain several small wins, but the paytable shows how modest regular wins are next to the fish values in free spins. If you plan to play Big Bass Bonanza Megaways online for real money, size your stake for the stretches between Scatters, not for the bonus you hope to see.

What the 4,000x cap means at real stakes

The rules state a maximum win of 4,000x the stake, and they enforce it: a free spins round stops once it has paid that much. The fish money symbol can also show a 4,000x value. The two are separate rules that happen to share a number, which means a single top fish already reaches the round's ceiling.

These are ceilings, not targets. With medium volatility, the game is built to pay a mix of small base game wins and occasional larger free spins rounds, and the cap is reached rarely. In the base game the best regular pay is the fishing float, at 50x the bet for six of a kind.

On RTP, the sources disagree by a hair. Pragmatic Play's game page lists 96.70%; the demo's rules and its game data both give 96.72%. We show the provider page figure in the facts table, but the build a casino runs may state either. Check the game's information screen once it is open; our RTP versions guide shows where to look.

Where it sits in the Big Bass family

Reel Kingdom has built a long series on the same fishing idea. The series includes Big Bass Bonanza, Big Bass Bonanza 1000, Big Bass Splash, Bigger Bass Splash, Big Bass Bonanza - Keeping it Reel and Big Bass Bonanza - Reel Action.

What makes the Megaways version its own game, going by its rules:

• A changing six-reel set with up to 46,656 ways, instead of fixed paylines.
• Tumbling wins in the base game and free spins.
• A Wild that only appears on the top row.
• Dynamite and bazooka modifiers for empty free spins.
• A 4,000x cap and a matching 4,000x top fish value.

Play Big Bass Bonanza Megaways free in the demo

Pragmatic Play's own demo is the cleanest way to play Big Bass Bonanza Megaways free. On 29 October 2026 we loaded it and it rendered in full: the intro screen, the base game with a C$100,000 play-money balance at a C$2.00 bet, and all seven pages of the game rules. Nothing you win in it is real, and no account or deposit is needed.

The Big Bass Bonanza Megaways slot demo is useful for three checks:

• Open the rules and confirm the RTP and volatility label of the build in front of you.
• Watch how often the reel heights reach the full six, so the 46,656 figure stops feeling like a typical spin.
• Trigger a few free spins rounds to see how rarely the second and third retrigger come.

The demo runs in the browser, with nothing to download. Once you move to a casino, the game should look the same, but the stake range and the RTP version are set by that casino. More free games from the same studio and others are on our free slots page.

No feature buy and no ante bet

Some Big Bass games let you pay to enter free spins. This one does not. The game data for the international build shows no purchase option and no ante bet, and the rules describe none. The only way into the bonus round is to land three or more Scatters.

That has two effects. You cannot pay a lump sum to skip the base game, which keeps the cost of a session tied to the number of spins you play. It also means the free spins arrive when they arrive; a long run without Scatters is part of the design. If you prefer games where the bonus can be bought, our bonus buy slots list collects them.

Whatever you play, decide on a spending limit first. Tumbles and long free spins rounds can make a session feel shorter than it is. Our responsible gambling page lists provincial tools and helplines.
