How to Play

To steal the treasures of the ocean-themed slot, you will need a bet of €0.75 to €45,000, your mobile device, a tablet, or a desktop computer, and if you are playing for real money, then you will need to create an account.

Before diving in, you should probably learn how to play the slot machine first. The following steps should help you get started.

  1. Sign up to any of the casinos recommended above and make a deposit
  2. Find Ocean Spin Kingdom's Treasures from the available games and click it to launch. You may have to use the search bar for easier access
  3. Choose how much you intend to stake from the dropdown in the bottom left corner
  4. You can also use the turbo button to place the maximum bet for faster spins and the max bet
  5. Click on the yellow spin icon on the right to start playing the game. An autoplay function also spins the reels automatically until a condition is met

The minimum stake for Ocean Spin Kingdom's Treasures is €0.75, and you can stake up to €45,000. Since the slot works on a multiplier, wagering a higher amount makes it likelier to win more. The game only has 75 paylines, so it is not a task to get the correct symbols on the right paylines.

Ocean Spin Kingdom's Treasures RTP and Volatility

8 

Ocean Spin Kingdom's Treasures RTP rate and volatility are on the average level.

As is the custom with many Konami slots, Ocean Spin Kingdom's Treasures RTP and variance are average, which is OK but nothing special. Based on our experience of playing this slot, you can expect medium payouts occurring occasionally.

Theme

9 

Ocean Spin Kingdom's Treasures has an ocean-aquarium theme that features a tremendous underwater look that evokes a sense of adventure and a soundtrack that provokes excitement. The gameplay is enticing with cascading reels, respins, scatters, and wilds. The visuals also feature an underwater style, and the background is filled with different colors of underwater coral. The game is centered around a wooden frame with four columns and five rows.

There are 13 symbols on Ocean Spin Kingdom's Treasures, all of which are either low-value or valuable. You win when you land 3 or more winning symbols on a payline.

The more lucrative symbols include two golden clamps, two golden fish, an octopus, a gladiator fish, a sea horse, and a lobster. The A, K, Q, J, 10, and 9 pay the least anywhere on the paylines.

However, Ocean Spin Kingdom's Treasures has a dedicated Scatter or Wild symbol. The two golden clamps double as Scatters, which pay the highest, unlocking some excellent bonuses.

Bonus Rounds & Free Spins

7.5 

Ocean Spins Feature

This feature is activated when you spin any 3 or more clamp shells. The total credit bet is the same as the game that activated the ocean spin feature. Any 2, 3, 4, or 5 gold clamp Scatter symbol awards an additional 5, 8, 10, or 20 free games during free games.

Wheel Bonus

When the wheel bonus is activated, one spin of the wheel is awarded. These bonus credit prizes are either 10x to 2,000x multiplied by the betting line. The bonus credit prizes are shown on the gold medallion after they have been multiplied by the bet per line.

The odds of winning the wedges are not equal. The values on the wheel will be multiplied by the base credits before the spin starts. You will have to swipe the wheel or press the spin button to spin the wheel.

Ocean Spin Kingdom's Treasures Demo Play

Using money is not a requirement for playing the game's demo version, which is accessible from this page. The demo version is for you to hone and master how the game works before you invest real money into it. The demo version starts you with €5,000, and it is the exact version of the game minus the part where you have to deposit or create an account.

Max Win

8 

The max win on Ocean Spin Kingdom's Treasures is €1,000,000.

The maximum potential winnings on Ocean Spin Kingdom's Treasures slot are €1,000,000. This figure is relatively high, as some games pay less than half of your stake when you win. The maximum multiplier is good, and Ocean Spin Kingdom's Treasures gives you the power to stake big on the payline.

With its €45,000 maximum wager, the highest you can win from the game is €1,000,000. While that sounds like a lot, it doesn't hold a candle to the potential earnings from some other slots. However, you should always expect something like this from Konami.

Overall Rating

8.1

Ocean Spin Kingdom's Treasures is one of the most enjoyable slots out there for the little bonuses it offers here and there. While the max multiplier seems pretty low, it takes work and luck to hit it. When you understand how the slot works properly, you get hooked. The game is not only interesting, but the interface is also attractive.
