Turns out game providers are never going to run out of ponds! Our Fish Tales Monster Bass slot review takes a look at Booming Games’ 2025 fishing-themed slot with a 5x3 layout, 20 paylines, high volatility, and a 5,000x max win. The game has 96.1% RTP and uses a familiar Cash Collect setup, where the Fisherman Wild collects Cash symbols from the reels. It is clearly playing in the Big Bass pond, but it has enough Booming Games polish, humour, and feature activity to avoid feeling like a cheap knock-off with a fishing hat.



Fish Tales Monster Bass is a 5 reel, 3 row slot with 20 fixed paylines. Wins form from left to right on adjacent reels, starting from the first reel. You need at least 3 matching symbols to form most wins, although the higher-paying red boat symbol can pay from 2 symbols.
The RTP is 96.1%, which sits in a healthy range for modern online slot games. The bigger warning is volatility. This is a high-volatility game, so you should expect a sharper rhythm. The base game can produce Cash Collect wins, but the real value sits inside the Free Spins round, especially when Monster Bass symbols land with large values.
The max win is 5,000x the bet. That is solid for a fishing slot. It is not extreme, but it gives the game enough upside to justify the higher variance. Just do not treat it like a quiet little fishing trip because this pond has teeth.
There are lots of different online casinos where you can play Fish Tales Monster Bass. Here is our pick of the best slot sites:
Fish Tales Monster Bass goes for a bright, sunny fishing theme, with a dockside setting, sea views, tackle icons, and the sort of cheerful art style Booming Games often handles well. It is colourful without looking messy, and the symbols have a bit more character than the usual “man holds fish, fish has number, everyone claps” setup.
The audio is light and outdoorsy. It has that relaxed fishing-trip tone, with just the right amount of slot-machine sparkle.
The lower-paying symbols are the card ranks 10, J, Q, K, and A. The higher-paying symbols include a red worm, fishing rod, life buoy, bait box, and red boat. The red boat is the top regular symbol, paying the strongest line wins from the standard symbol set.
The Fisherman is the Wild symbol. It substitutes for regular symbols and also collects all visible Cash symbols when both land in view. That makes the Wild much more important than a basic substitute. The Cash symbols can carry values from 0.25x up to 1,000x the bet. During Free Spins, the stacked Monster Bass symbols hold the largest values and become the main catch of the round.
The Scatter is the red and white fishing float. Landing 3, 4, or 5 Scatters triggers 10, 15, or 20 Free Spins. The game also uses a Barrel Boost system above the reels, which collects Scatter symbols and can add more Scatters to help trigger the bonus.

Fish Tales Monster Bass is a 2025 Booming Games release, so mobile play is clean and modern. The 5x3 grid fits neatly on phone screens, the 20-line layout does not overcrowd the display, and the symbols are large enough to read without squinting like you are checking a fishing licence in the rain. The Extra Bait and Feature Buy buttons sit on the side, while the usual spin and bet controls stay easy to access. It is a busy game in feature terms, but the mobile layout handles it well.



Fish Tales Monster Bass has a busy feature set built around Cash symbols, Wild collection, Free Spins, and Monster Bass prizes. The game clearly borrows from the modern fishing-slot formula, but it adds a few useful base game modifiers.
The Fisherman Wild substitutes for all regular symbols, but not Scatters or Cash symbols. Its bigger role is Cash Collection. When the Fisherman Wild lands with Cash symbols in view, it collects all their values. This means a Wild can create line wins and also trigger direct cash payouts in the same spin. In practical terms, this gives the base game a better chance of doing something useful before Free Spins arrive.
Cash symbols can carry values of 0.25x, 0.5x, 0.75x, 1x, 2x, 3x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, 250x, 500x, and 1,000x the bet. When a Fisherman Wild appears on the reels, it collects every visible Cash symbol. This feature works in the base game, which is a major plus. It stops the slot from relying entirely on bonus entry and gives you some feature action without needing Scatters every time.

The Barrel Boost feature uses a wooden barrel above the reels to collect Scatter symbols. When Scatters appear, they can be gathered into the barrel, and the feature may randomly add Scatters to the grid. This can help trigger Free Spins. It is a smart support feature because fishing slots can get frustrating when two Scatters keep appearing and the third one treats the reels like a crime scene.
Big Net is a random base game modifier. When it appears, it collects and awards all Cash symbols in view, even without a Fisherman Wild. This gives the game another way to pay Cash symbol values outside the Free Spins round. It is not as exciting as landing a huge Monster Bass in the bonus, but it adds a useful surprise moment to the base game.
Cash Add can trigger when a Fisherman Wild lands without any Cash symbols. Instead of letting that Wild do very little, the game can add Cash symbols to the reels and create a collection. This is one of the better small touches in the game. It reduces some of the dead-spin feeling and gives Wilds more value even when the reel drop looks poor at first.
Free Spins trigger with 3, 4, or 5 Scatters, awarding 10, 15, or 20 Free Spins. During the round, Fisherman Wilds are collected on a progress trail above the reels. Every 4th collected Wild awards 5 extra Free Spins, with up to 15 extra spins available.
The headline here is the Monster Bass symbol. If 3 stacked Cash symbols land, they create a Monster Bass carrying a value of 50x, 100x, 250x, 500x, or 1,000x the bet. The Monster Bass covers a large reel area and nudges down after each free spin if not collected. If a Fisherman Wild collects it, it nudges back up. This is the main money feature and the best reason to reach the bonus round.
Extra Bait is the Ante Bet feature. It costs 50% extra on top of your current bet and increases the chance of triggering Free Spins. It can suit players who want more bonus action, but it also raises the cost per spin, so casual players should be careful with it.
The Feature Buy gives two options.
You can buy regular Free Spins for 75x your bet, or Free Spins with a guaranteed Monster Bass for 100x your bet. The second option is the more interesting one, because the Monster Bass is the feature everyone is really chasing.
Still, buying bonuses on a high-volatility slot can rinse a balance quickly.
The game saw the Big Bass formula, packed a tackle box, and joined the trip. But to its credit, it does a few things right.
The base game is better than expected because Cash Collection can happen outside the bonus. Big Net and Cash Add also help. That alone gives it an edge over fishing slots where the base game often feels like a loading screen with reels.
The Free Spins round is where the real chase begins. Monster Bass symbols with up to 1,000x values are the selling point, and the extra spins trail gives the bonus some progression. The missing piece is a total multiplier. Big Bass fans will notice that straight away. Without it, the bonus can feel slightly capped, even though the 5,000x max win is perfectly respectable.
Visually, I like it. It is colourful, readable, and has more charm than the usual copy-paste lake trip. The fisherman, tackle symbols, and summer-day setting give it a lighter mood. It is a good fishing slot for players who want high volatility, solid Cash Collect action, and a bonus round.
Fish Tales Monster Bass gets a 7 because it delivers a polished fishing-slot experience with a fair 96.1% RTP, 5,000x max win, proper base game Cash Collect action, and a strong Monster Bass feature in Free Spins. It loses a little ground because the theme and structure are very familiar, and the lack of a total multiplier makes the bonus less explosive than some rival fishing slots.
