Ocean Gems Bonanza Slot RTP, Details & Wager Limits

Reels/Ways to Win: 6 reels + scatter pays

Stakes Range: 25p to £250 per spin

Max Win: 10,000 x bet

RTP: 96.5%

Ocean Gems Bonanza is played on a 6-reel, 5 row game grid. Create winners by landing 8 or more matching symbols anywhere on the reels. They don’t have to be in paylines or on adjacent reels, anywhere will do as long as there’s a minimum of 8. 

You can play Ocean Gems Bonanza at stakes of between 25p and £250 per spin. Click on the coins icon above the spin button then scroll through the different values. 

If you’re in a territory where it’s allowed, there’s the chance to activate autoplay. This lets the spins run indefinitely rather than offering a defined number. There’s also a quickspin mode. Neither of these are available to players in the UK. 

Most versions of Ocean Gems Bonanza come with a better than average 96.50% RTP. There are also versions with 94% and 89.5% return to player rates. 

The hit rate delivers a winning combination every 2.32 spins on average. The volatility sits comfortably in the medium range.

The Ocean Gems Bonanza maximum win is 10,000 x stake.

Theme: enjoy an underwater adventure

High-Value Symbol: Crab

The colourful, cartoon-style visuals in Oceans Gems Bonanza are nicely done. You’ll see tranquil turquoise waters and a selection of aquatic plant life behind the deep blue reels. Those reels feature four shell symbols, and five higher-paying fish. The most lucrative symbol is the lobster which delivers 40 x stake if you land 12 or more anywhere on the reels on the same spin. 

The rainbow pearl is the game’s scatter symbol. Land 3 or more these on the same spin to trigger the bonus round. Joining the action during the free spins is the pearl shell which can deliver some chunky multiplier boosts. 

I liked the rather twangy soundtrack which has a gentle feel and works well in combination with the colourful visuals. There’s an option to turn off the sound if the bangs and pops that accompany winning cascades become a bit too much though. 

Here’s what the symbols pay:

Ocean Gems Bonanza Mobile

The colourful design and simple gameplay make the Ocean Gems Bonanza mobile slot a very straightforward one to play. You won’t lose anything playing on a tablet or smartphone with a smaller screen. It’s available on iOS, Android and Windows handsets. 

Ocean Gems Bonanza Bonus Features

The gameplay in Ocean Gems Bonanza is simple. You won’t find a huge range of extras here. The action ticks over courtesy of the cascading reels but can explode into life during the free spins feature. 

Cascading Reels

Land a winning combination and those successful symbols are blasted from the game grid. New symbols drop in to replace them and a new payout consideration follows. These cascades keep on coming as long as a new winner lands. 

Free Games feature

ocean-gems-bonanza-slot-free-games-feature

Trigger the bonus round by landing 4, 5 or 6 scatter symbols anywhere on the reels on the same spin (including cascades). You’ll then go on to play 10, 15 or 20 free spins. Joining the action here is the pearl shell multiplier symbol. This symbol can boost payouts by between 2x and 100x.

Land more than one pearl shell at the same time and the value of the multipliers is added together to deliver even bigger payout boosts. Multipliers can get as high as 1,000x here. Re-triggers are possible too. Land 3 scatters and five more free spins are added to your current tally. 

Buy Bonus feature

Players in some territories (but not the United Kingdom) will be able to buy a feature. There are two possible choices. 

  • Standard Free Games – You’ll receive 10, 15 or 20 free spins. Cost = 100 x stake.
  • Upgraded Free Games – You’ll receive 10, 15 or 20 free spins. All multipliers that land have a minimum value of 10x. Cost = 250 x stake.

Ocean Gems Bonanza Verdict: random multipliers can help boost potential wins

Ocean Gems Bonanza Slot

Super Lion Megaways comes with win both ways payouts, wild reel respins, free spins and a progressive jackpot. It also offers over 33 times the win potential of the original Super Lion slot.

Pros
  • 10,000 x bet max wins
  • High 96.5% RTP rate
Cons
  • Basic gameplay for Megaways slot
  • No multipliers in free spins

There are countless underwater-themed slots and I found Ocean Gems Bonanza to be a perfectly playable new addition to those crowded waters. 

There’s nothing revolutionary on offer here. The cascading reels keep things ticking over though and the free spins round with the big potential multipliers is a very decent feature round. I landed the free spins round regularly and enjoyed some solid rather than spectacular wins. 

Visually, Ocean Gems Bonanza is fine. Again, it doesn’t really stand out but is perfectly acceptable.

The 96.51% RTP is a better than average figure and the 10,000 x stake maximum win is certainly of interest. 

Put that combination of gameplay, design and stats together and the waters in Ocean Gems Bonanza are certainly worth dipping your toes.

For a couple of underwater alternatives, consider Red Tiger’s Fishtastic slot and ELK Studios’ Oxygen slot. They come with 6,125 x and 25,000 x bet max wins respectively.
