Play Tuna Overload Multiplier Slot Game

Cast your nets and head deep into Tuna Overload Multiplier, Spinberry’s medium-volatility fishing-themed slot. Choppy waters, two features, and big catches await.

Tuna Overload Multiplier is the third in Spinberry’s Tuna Overload series. It follows Extreme Tuna Overload, which was released in April 2025.

You'll recognise some familiar characters if you’ve played the other games, but several new gameplay aspects make this one worth playing.

This slot has no standard payouts because all wins happen in the Collection Feature and Lock and Spin Round. You can enhance your gameplay and increase the chances of landing these features, which you can do using the icon next to the reels. By doing this, you’ll double your bet.

The 6x4 reels contain a small number of symbols, mainly fishing floats and tuna (with multipliers). You can also land the boat scatter and the collector symbol to trigger features.

Beyond the reels, choppy waters await, but thankfully, if you get seasick, you can enjoy this game from the comfort of your home at Parimatch Casino.

Unlike other slots where you must match symbols from left to right, there are no standard payouts for symbols in Tuna Overload Multiplier. Instead, you can land winnings via the special features.

The reels are made up of just four symbols:

• There are different tunas with multipliers, where the larger the fish, the bigger the multiplier. You could land up to x100 on a single fish.
• Collector symbols, which can reel in the multiplier rewards.
• Boat scatter symbols that can trigger the Lock and Spin feature if you land three of them.
• Fishing floats to fill the reels with no value.

Tuna Overload Multiplier is all about the features, as this is exclusively where you can land payouts. Enjoy two features: the Collection Feature and the Lock and Spin Feature.

You can increase your chances of landing these features by clicking the icon under the reels and next to your stake; this will double your bet.

Collection Feature

As you spin, you’ll land tuna symbols, each with a multiplier. The larger the fish, the bigger the multiplier. These multipliers can be x0.5, x1, x1.5, x2, x2.5, x3, x4, x5, x7.5, x10, x20, x25, x50, x75, or x100.

You could land the fisherman collector symbol on reel six with any tuna (and their multipliers) on the reels, and if you do, the fisherman will collect all the fish and their multipliers to award you a win.

Lock and Spin Feature

You'll access this bonus round if you land three boat scatter symbols. You’ll initially be awarded three free spins, but you’ll have opportunities to get more.

When you unlock this feature, you’ll hear the ship's bell, and the scene will turn from dawn to dusk, because all the best things happen at night.

During Lock and Spin, any tuna symbols (and their multipliers) that land will freeze in place until the end of the feature. Not only that, every time you land a tuna symbol, the re-spins will reset to three.

The bonus will end when you finish your re-spins or the reels are full of fish. When the feature is complete, fish are added to the net while the game counts up your winnings; a satisfying watch.
