  • Exciting free spins feature with bonus multiplier
  • The starfish bonus allows for bigger wins
  • The music is spot on and not overpowering
  • An RTP of just 92.00% is pretty low
  • The variable volatility level isn’t ideal

Deep Blue Treasures is an online slot developed by Casino Web Scripts. The RTP of this five-reel, 25-payline game is 92%, while the volatility level varies. Bonus features include free spins and three jackpots.


Zip up your wetsuit and dive right into this fascinating underwater world. You will share the space with charming creatures, including fish, turtles, seahorses and starfish. Deep Blue Treasures is a typical example of Casino Web Scripts free slots, which always offer both a visual treat and some fun ways to win.

Graphics & Soundtrack

The game opens to a beautiful underwater world with clear blue water, shells and stunning coral. Overlaying this are the reels, designed to look like five separate tanks. There you will find a mixture of symbols with a connection to the sea, including a turtle and a shark. Watch out for the killer whale, as the wild he can replace any of the regular symbols to help make winning combinations.

The relaxing instrumental music is perfect for the game, and it doesn’t drown out the pleasant tinkling of spinning reels. Prepare yourself for the loud fanfare which bigger wins will trigger.

The return to player rate of this slot is a measly 92%, which is considerably lower than average. There is no set volatility level, as this can be adjusted by the casino hosting the game.

How to Play Deep Blue Treasures

Most slots share similar features, but as each game looks different it’s good to spend a little time getting familiar with a slot before the spinning and wagering starts. Here’s a quick guide to getting this one ready to go.

1.    After the game has loaded click on the cog to display a menu for support options. You can choose speed of play, to allow or mute the music, and change to full screen mode if you like.

2.    Check out the paytable information via the button showing three short horizontal lines.

3.    Use the plus and minus buttons at the bottom of the screen to choose both the number of lines to wager on and the coin size to stake per line. It’s probably wise to start lower and increase things as you become more familiar with the slot.

4.    If you want to try autoplay set it to spin from five to 25 times. There’s also a stop menu, which allows players to set limits which will cancel this automatic function when reached.

5.    Spin and enjoy playing responsibly.

Bet Sizes & Paytable Wins

Players have an incredible range of bet sizes at their fingertips, with the minimum possible being 0.01 and the maximum allowed set at 10,000.

One of the most important things for players to know is what kind of payouts they can expect from the symbols in a slot. So let’s take a look at Deep Blue Treasures paytable. The icons pay for either two to five or three to five matches, and here’s what five of the same will earn you.

Shark/turtle = 750 coins

Goldfish = 400 coins

Starfish/seahorse = 250 coins

A & K = 150 coins

Q & J = 100 coins

10 = 10 coins

Deep Blue Treasures Bonus Features

There are plenty of extras on offer in this underwater extravaganza. Let’s take a closer look at the options players have to boost their coin stash.

The Bonus

Players are shown a screen with five starfish, which they click one by one to reveal the bonus behind it. This isn’t a hit and run feature, though, as you can keep on clicking and building your winning pot until you choose a starfish with the word ‘collect’ alongside the number of coins awarded. This bonus can only be triggered during main game play.

The Free Spin Scatter

Landing 3+ oyster and pearl scatters anywhere on the reels on one spin will bag you a double prize.

3 scatters bring 5 free spins
4 scatters mean 15 free turns
5+ scatters award 33 free spins

And each free spin session is rewarded with a random multiplier feature of between one and 15. (There are no free spins if the jackpot is triggered.)

The Jackpots

There’s not one, or even two jackpots offered here - instead there are an incredible three of them (major, mega, mini), triggered by filling the reels with scatter symbols.

The Gamble

Every win offers you the chance to double your winnings from that spin or lose them. That’s the risk. To cash in means correctly predicting which of two colours will be revealed. Success at this stage offers the option of trying to double the new amount with another correct answer (up to 5x if your luck holds) or exiting with winnings.

Our Verdict

It’s fair to say that we enjoyed playing this slot; in fact, every spin had enough edge to make it exciting and fun. Sadly, the low RTP does knock some of the shine off it, but in terms of entertainment it is still worth a look.

If you enjoyed this ocean-themed slot, there are plenty more with a similar theme to have a few spins on. We have to give a shout-out to Mermaids Millions slot, which combines an old school look and features with a high-end bet option, an attractive low to medium volatility rate and an impressive 96% - 97% RTP.
