Just what the casino world needs, another fishing slot, right? I know, I rolled my eyes too when I first fired up Bass Catch Super Luck by Microgaming. But after spending a few hours on the water, I have to admit there’s a bit more going on under the surface here than your standard Big Bass clone.
Built on a 5×4 grid with 1,024 ways to win, the standard paytable is honestly just window dressing. The real engine driving this game is a Cash Collect mechanic tied to a persistent multiplier trail. It’s a slow-burn slot that requires some patience, but when the features finally align, it packs a serious punch. Here is my honest breakdown.
A River Full of Untouched Fish (The Base Game)
The frustrating part first: you are going to stare at a lot of dead fish.
During the base game, Cash Bass land on the reels carrying values from 0.2x up to 10x your bet, alongside four fixed jackpots that peak at a 1,000x Mega. The downside is that absolutely none of these pay out unless the Fisherman symbol lands on reel 1 or reel 5 on the exact same spin.
Unlike a recent Microgaming title like Bolts of Zeus Coin Grid, where jackpot coins stick to the board until collected, in this game, if the Fisherman doesn’t show, the fish simply swim away. Over my 300-spin test session, the Fisherman showed up roughly 10% of the time. Because the board is almost always littered with cash values, the base game can feel like a relentless tease. When you do get a collect, the hits are usually modest. My best base-game hit was a Fisherman reeling in two 15x Mini jackpots for a 31.5x payout. It kept the balance ticking over, but it won’t blow your mind.

The Super Up Trail: Grinding for Multipliers
To make up for the tease of the base game, Microgaming has added the Super Up trail down the left side of the screen. This is a multiplier ladder ranging from 1x to 15x, and it’s the reason the base game matters at all. Note: this multiplier only applies to collected fish and jackpots, not standard line wins.
Here is how you climb it:
- Red Scatters: Landing two of these awards a token, moving you one step up the active multiplier ladder.
- Blue Scatters (Outer Reels): These are great. They permanently upgrade the actual values on the ladder for the rest of your session (e.g., turning a 10x rung into a 12x rung).
- Gold Scatters (Reel 1): These apply your current active multiplier to a base-game collect.
To be fair, a Gold Scatter only does anything when a collect lands on the same spin, and that pairing is rare enough that the trail is really just an elaborate setup for the Free Spins. However, the permanent blue scatter upgrades do give the base game a great sense of progression, making the dry spells a lot easier to sit through.
Free Spins & The Upsize Menu
Landing three Red Scatters triggers 8 Free Spins, and this is where the game’s math finally makes sense.

Before the round begins, you’re greeted by the Upsize Menu. This gives you the option to pay a premium to start your free spins at a higher multiplier level. The clever part? Any tokens you collected in the base game discount this cost. You can, of course, just decline and play at your current free level.
Once the bonus starts, the layout is the same, but the Fisherman hits the water about four times as often, and your trail multiplier is applied to every single collect. In one natural trigger, I started at a 3x multiplier. Thanks to a retrigger and my previous permanent blue scatter upgrades, I pushed the multiplier to 8x. That round paid out a sweet 77.6x my bet, driven mostly by individual fish paying 25.6x and 28x. Suddenly, a measly 5x bass turns into a 40x payout in a single sweep.

The Verdict: Chasing the 15,000x Cap
Bass Catch Super Luck runs at a 96.2% RTP, and the max win is 15,000x your bet. Because the multipliers completely ignore standard symbols (a 5-of-a-kind wild line pays just 5x, and it will never be multiplied), the route to the cap is entirely dependent on the fish. You are chasing one miracle spin in the bonus round: maxing out the trail to 15x, landing the Fisherman, and snagging the 1,000x Mega Jackpot.
A lot of this game is cash symbols landing with no collector to take them, and that tease never really goes away. What it gives back is progression: the base game builds something permanent toward a highly volatile bonus round, and on that front Bass Catch Super Luck is a fair, well-designed release. It asks for patience, and the bonus is where the patience gets paid.
