Secret of Ocean is an online slot developed by KA Gaming with 5 reels and 40 fixed paylines. Both the RTP and variance are unknown for this nature-themed slot. It has a mystery symbols feature and free spins bonus, with a top 5,000 coin prize on the max stake.


Secret of Ocean is a fresh release for 2021 from Taiwan-based developer KA Gaming, taking a 3x5 format with 40 fixed paylines. With its nature theme, this slot is full of oceanic wonders and a secret or two below the rippling surface awaiting your discovery.

Below the reels are the user controls with a minimalist design, overlaid on the backdrop so as to blend in. Win amount and total bet are to the right. Bet adjustment, spin and max bet are in the centre. Balance and game information are to the right. Oceanic crystals to either side of the reels tell us that 40 paylines are in play. 

There are 10 base game symbols, including the likes of a dolphin, sea turtle, octopus, seashell, map, anchor and more. The blue diamond is the Wild, substituting all symbols except for the Scatter. The red-haired sea woman is the Mystery Symbol.

All symbols bar the scatter pay on active paylines from left to right. All wins are multiplied by the bet per line, bar scatter wins, which are multiplied by the total stake.

All of our KA Gaming slots are 100% free demos that you can enjoy without risking your own cash. Dip your toes in the water today and see if the ocean offers up her magical secrets. 

Theme, Graphics & Soundtrack

The nature genre is as beautiful as it is grounding. When overwhelmed with the hubbub of modern-day life, escaping to natural surroundings can be very calming and refreshing. The ocean is of particular magnificence, for there are so many intriguing plants and creatures that we can only dream of hiding below the surface. Myths and legends tell us of hidden treasures and gorgeous mermaids, making the shimmering water of our oceans all the more scintillating. 

The backdrop is a deep blue-green ocean, with rock formations to provide depth and reflections of light that make the water glisten. The reels are very simple, with only a light outline as each reel is divided separately and given a darker green background so as to make the symbols pop. The symbols themselves are bright and cartoonish in style, with enough detailing to be good quality while retaining that youthful, fun vibe. 

Animations are understated but smooth. Instead of an ongoing soundtrack, upbeat sound effects and ocean waves dance through the slot to keep things light and vibrant.

Secret Of Ocean Review Overall

This is a pretty straightforward slot to get to grips with and it’s easy on the eye, too. While it may not offer anything earth-shattering, the graphics and sound effects work well to provide a beautiful, calming atmosphere. We like the mystery symbols to create a little suspense and the free spins to boost chances of scooping prizes. These bonus elements are fairly simple and classic, so those who like novelty and newness may find the slot a little dry.

Super casual players may find the 0.40 minimum stake a little higher than what some slots offer, but the likely lower volatility might be more appealing. Meanwhile, higher rollers should appreciate the generous top stake and the max 5,000 prize isn’t too shabby, either. 

Dive in to more fishy fun with the Queen of Atlantis slot from Pragmatic Play. You’ll be treasure hunting the underwater city, with potentially unlimited free spins, super scatters and extra wilds on offer.
