If you’re tired of spinning traditional slot reels, BGaming’s Aquamasters might catch your eye. It’s a crash game that trades the casino grid for a submarine dive. If you’ve played Aviamasters 2, most of this will feel familiar, since they basically just swapped the sky for the ocean floor.
The math is solid: a 97% RTP (Return to Player), a 1,000x max win, and high volatility. But what really makes this game stick in your head (and maybe haunt your dreams) is the sheer tension of the final climb. Why? Because the multiplier you spend the whole round building doesn’t actually belong to you until you safely reach the surface.
Chasing Bubbles (and Dodging Mines)
Here’s how a round works. You launch a little yellow sub that dives down to the seabed, moves forward, and eventually climbs back up. Along the way, you collect bubbles. Blue ones add a flat number to your multiplier, and green ones multiply whatever you’ve already got. Hitting a green bubble late in your run is an awesome feeling because your payout suddenly skyrockets.
But there are also mines in the water. Hit one, and your hard-earned multiplier gets sliced in half. The game does throw you a bone with some fun power-ups, a magnet to grab bubbles, a rocket to blow up mines ahead of you, and a lifebuoy for an extra life. It’s really entertaining to watch your numbers climb, but honestly, none of it matters if you don’t survive the final ascent.

The Heartbreak of the Aircraft Carrier
This brings us to the most stressful rule in Aquamasters. Waiting at the surface of the water is a massive aircraft carrier. If your sub bumps into it on the way up, your payout is zero. Zilch. It does not matter what your meter says.
During my playthrough, I found out exactly how heartbreaking this can be. In just a short session, I had one run build up to an x32 multiplier, only to slam into the carrier and lose it all. Another time, I was sitting pretty at x31 right near the surface, crash. Gone. I even had a run where a mine chopped my x17.5 down to x8.8, and then the ship finished me off anyway. You either survive the carrier or you don’t.
(And just a heads-up: even if you do survive, you might surface with less than x1.0 on your meter, meaning you only get a fraction of your bet back. So a “win” can still slowly drain your balance).

What Safe Surfacing Actually Buys
To help with the stress, the game gives you a toggle switch called “Safe Surfacing.” It costs 50x your base bet, and it puts your sub in a protective bubble, guaranteeing you get past the carrier and keep your multiplier.

Sounds great, right? Well, here’s the catch. Your win is multiplied by your base bet, not the 50x you just paid. So, to simply break even on a bought round, your sub has to rack up an x50 multiplier. Oh, and that protective bubble? It doesn’t stop the mines from halving your score on the way down. I played twenty-five regular rounds and one bought round, and finished the session about 9x my base bet down. The math requires a big, lucky run just to cover the cost of the feature.
The Verdict
A 1,000x max win is a little low for a crash game. For comparison, BGaming’s own Wincent Wolf, a traditional reel slot, goes up to 10,000x with the exact same 97% RTP.
Aquamasters trades huge jackpot potential for short, sharp, highly volatile rounds. The 97% RTP is a really strong baseline, and it holds with Safe Surfacing switched on too, but at 50x a round the feature needs an x50 meter just to pay for itself. Without it, every round comes down to the climb and that aircraft carrier, and in my session the carrier took some of my best runs.
