The Big Catch slot review

What is The Big Catch slot?

This game comes from Blueprint Gaming, the UK studio based in Newark that also makes Fishin’ Frenzy, Eye of Horus and King Kong Cash. Some casinos list it as Fishin’ Frenzy The Big Catch, which signals where it sits: it’s a variant of Blueprint’s best-known fishing slot rather than a brand-new design.

The grid is the familiar one for the series: 5 reels, 3 rows and 10 paylines. The appeal lies in the bonus, where fishermen collect fish prizes and the round can grow as you collect more of them.

Where a figure isn’t published, we leave it blank rather than guess. The game’s own help and paytable screens inside your casino app are the most reliable place to look.

How the features work in The Big Catch

Outside the bonus, The Big Catch plays as a straightforward 10-line slot: matching symbols on a payline from left to right pay according to the paytable. The interesting part starts with the bonus symbols.

Triggering free spins

Land three or more bonus symbols in one spin and the free spins round begins. The paytable inside the game shows how many spins each number of bonus symbols awards.

Fishermen and fish prizes

During free spins, fish symbols carry prize values. When a fisherman lands, he collects a prize for every fish on screen at that moment. A spin with several fish and a fisherman pays out all of those values together, because the fish prizes are paid through the fisherman’s collect.

Collecting fishermen to upgrade the fish

Every fisherman who lands is also added to a running count. Each time that count reaches another four, two things happen: the fish are upgraded to higher values for the rest of the round, and five extra free spins are added.

That makes the round self-reinforcing. More fishermen mean more collects, a longer round and bigger fish, so a bonus that keeps finding fishermen can be worth far more than one that doesn’t.

The Big Catch slot RTP: what 95.32% costs you

An RTP of 95.32% means the game returns £95.32 for every £100 staked over the very long run. The house edge is therefore 4.68%, and that’s your average cost: stake × 4.68%.

That’s a noticeably higher cost than games around 96%. On £100 staked, the difference between a 95.32% game and a 96.12% game is 80p on average. It sounds small, but it adds up over a long session, as the Wizard of Odds house edge explainer (opens in a new tab) shows with its own examples.

As an hourly guide at an illustrative 300 spins an hour, a 10p stake costs about £1.40 on average, 50p about £7.02, £1 about £14.04 and £5 about £70.20. UK rules cap the pace at 1,440 spins an hour, so faster play costs proportionally more.

What a £20 session on The Big Catch looks like

With no published volatility rating, it’s safest to plan as if the bonus could take a while. These figures assume you stop when the £20 is spent.

The average loss is the same at every stake because it’s a percentage of the £20 you stake. A lower stake doesn’t change the cost; it gives you more spins for the same budget, and so more time and more chances to see the bonus.

How to check The Big Catch’s volatility and max win in your app

Because some key figures aren’t in the published specifications, it pays to read the game’s own information before staking. UK rules require games to make their rules and return information available to players, as set out in the Gambling Commission’s RTS 3 standard on game rules and the likelihood of winning (opens in a new tab).

1. Open the casino app and search the game lobby for The Big Catch.
2. Load the game, then look for the menu, info or question-mark icon on the game screen.
3. Open the paytable to see what each symbol and each fish pays at your current stake.
4. Read the game rules section for the RTP your casino uses and any stated maximum win.
5. Check how many free spins each number of bonus symbols awards.
6. Close the info screen and set your stake only once you understand the bonus.

Playing The Big Catch on iPhone and Android

A 5x3 grid with 10 lines is one of the easiest layouts to play on a phone. The base game is simple, and a 5x3 grid leaves room for each symbol to be shown at a readable size.

There’s nothing to download for the game itself. If The Big Catch appears in your casino app’s lobby, it loads within the app, and the same account and balance work across the app and the mobile site.

• Get casino apps only from the official App Store or Google Play listing. See our guides for iPhone and Android phones.
• Spin results are decided on the casino’s server, so if your signal drops the outcome stands; reopen the game to see it.
• Whether the game runs in portrait or landscape depends on the build; see landscape vs portrait mode.

UK slot rules that shape The Big Catch

The design rules come from RTS 14 (opens in a new tab). Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so the bonus only comes through bonus symbols. Read more on our slot stake limits and game speed rules pages.
