How to play Boat Bonanza Down Under mobile slot

The Boat Bonanza Down Under slot is a brilliant fishing slot by Play’n GO studios, where a little fisherman sleeps on a dingy, and wakes up to grab fish with up to 50x multiplier or great big sharks that he wrestles in the dark.

What a strange, wonderful theme! During the day, your fisherman is floating on a brilliant, clear ocean, probably somewhere on the Gold Coast, catching seagulls, cans, flip-flops, goggles, and Ace to J symbols. Hit the free spins, and you are now fishing in the dark, where you’ll want to catch great white sharks. You know. As you do.

Boat Bonanza Down Under is a 5×4 reel slot with 12 paylines. The reels feature instant cash symbols in the form of fish and crabs, and if the fisherman lands awake above the reels, you catch the symbols on the reels below. The top win if 6,000x your bet, with a high RTP of 96.25%.

Three scatters trigger 10 free spins with various random modifiers, and you can retrigger the free spins if you catch more scatters. Every bonus round feels a little different, thanks to those random bonuses.

In other words, Play’n GO is creating its version of the Big Bass Bonanza slot. Is it as good? Almost. The many modifiers add an extra flavour to the reels, but waking up that fisherman can feel like hard work.

The Boat Bonanza Down Under slot modifiers

Good news! This Boat Bonanza Down Under mobile slot doesn’t shy away from giving you plenty of the free spin bonuses. They trigger easily, usually within 50 spins or less. Which you need with a slot game like this.

Why? When you start your 10 free spins, you get one modifier. This usually removes one to three low-paying symbols, adds +5 spins, or guarantees catch symbols on the reels. If you are lucky, you may even get multipliers or more bonus triggers.

But, what you need, is for that damn fisherman on the reels to wake up and do his job. He moves around a lot in the base game and free spins, but does he catch much? No. So, not unlike a real fisherman.

If the fisherman lands with the scatter (the great white), the scatter is collected. You’ll need 2 to trigger either extra modifiers or extra free spins. That’s where this casino game gets interesting. But, again, it can feel like hard work getting those sharks to eat the skinny white dude on a rubber ring.

Can the Boat Bonanza Down Under slot give you big wins?

We like that this is a mid-to-high variance slot. It’s a little friendlier than the Bigger Bass Bonanza or the Big Bass Day at the Races, which makes it a nice little day game to play when you want to stretch the budget a little.

A little, but not a lot. This is still higher than normal, and the shark means business. You should be conservative with the wide betting range of 0.10 to 50 a spin bet and play some Boat Bonanza Down Under free spins to see what you think. If you like what you see, increase your bet slightly and go for it.

This is a fishing slot, so you need patience with the man on the rubber ring but don’t give up on him. When he wakes up, he can be pretty effective.

Sometimes, a wave comes along, and he surfs all along the reels, grabbing every fish you see. Or, even better, he fishes down deep and catches a huge 50x your bet crab, filling your wallet with wins. It’s a fun little slot machine that’s worth taking a spin on at any good Play’n GO Casinos.

Bonus Features

Fisherman Catch Instant Prize: A sleeping Fisherman above the reel moves around spin to spin. If he wakes up, one of two actions will occur

  • Catch Feature: Collect all the prize fish on the reels beneath the fisherman. The maximum catch symbol value is 50x.
  • Surf n Catch: The fisherman starts on the leftmost reel and surfs along the top of the reels, collecting all the prizes on all of them. You then also get a multiplier equal to the number of reels containing prizes.

Scatters and Free Spins: 3 or more scatters trigger 10 free spins. Before you start, you get to pick a single modifier for the reels. This includes:

  • +5 or +10 additional free spin
  • More Catch Triggers at x1 or x2 multiplier
  • More Surf n Catch Triggers at x1 or 2x multiplier
  • More Catch Symbols
  • More Catch Symbols and 2 lowest paying catch symbols removed
  • The lowest-paying symbol is removed
  • The 3 lowest-paying symbols removed
  • At least 1 catch symbol on every free spin
  • Catch multiplier increased to x2 or 5x
  • Up to 1 random catch symbol will be sticky for 1 spin
  • Up to 2 random catch symbols will be sticky for 1 spin

There's also a progression trail above the reels, and collecting scatters will help you progress along the trail. Every 2 steps along the trail, you are awarded either an extra pick of the modifiers or additional free spins. Positions 2, 6 and 10 offer extra picks, while positions 4, 8 or 12 retrigger 10 free spins. Win multipliers for each retrigger stage are x2, x3, and x10.

Scatters are only collected on the same reel as an awake fisherman. The maximum number of free spins that you can play is 50 free spins.


  • Free spins bonus comes with extra modifers and multipliers
  • Decent 96.25% RTP even though this can differ between casinos
  • Instant wins offer up more base game action


  • RTP can be lower at some slot sites
  • Free spins are little complicated than other slots

Boat Bonanza Down Under Review Conclusion

This doesn't quite reach the heights of the Big Bass Bonanza slots, mainly because the free spins are overcomplicated, and you want to shake the fisherman awake. We much prefer Piranha Pays, which is inventive and simple.

But that's not to say that this doesn't have some pretty crazy wins for a mid-to-high variance slot. This is mostly thanks to the many modifiers in the free spins, so you never quite know what you will get. It keeps things lively and on the edge of your seat.

And even if you get frustrated that the fisherman up the reels isn't doing much, you don't have to wait long for the next free spin round. We love any game that gives us value for money.

With a high RTP of 96.25%, you tend to find some decent wins - we managed to get over 80x our bet thanks to the fisherman and over 150x our bet in the free spins. That said, you can find this game at the much lower RTP of 94.25%, at which point forget the progression bar or the wins. Make sure you check out the paytable carefully before you play.
