Underwater World Slot Gameplay Interactive

Underwater World is a video slot with 5 reels and 15 pay-lines powered by Gameplay Interactive software provider. This slot is inspired with the underwater world where mermaids rule. Great design with cartoony look and adorable undersea creatures. The reels are of course set under water and there are 2 mermaids on each side from the reels. Give this slot a free spin here on this page or visit Gameplay Interactive Casinos to play for real money.

Before you start swimming you are advised to set your bets. By clicking on "Line Bet" you will control coins size which ranges from 0.10 to 6. "Spin" will set the reels in motion once, after you choose your betting range. "Auto Spin" is used to spin the reels without interruption for a chosen number of times, and "Max Bet" is used to set the maximum bet allowed and spin the reels. "Double Up" will start the gamble feature.

Shark is the Wild symbol is expanding and it substitutes for any symbol in the game except for the Scatter symbol. Wild doubles all winning combos when substituting in a win. For 5 Wilds on the active pay-line, you will win 10000 coins.

Mermaid is the Scatter and it can form scatter wins which are multiplied by the total bet. For 3 or more consecutive scatter you will be awarded with 15 spins and x3 multiplier. The feature can be re-triggered which means that if you land another 3 or more Scatters you will be awarded with another 15 spins which can be re-triggered infinite number of times.

Whenever you land a win you can gamble it by clicking the "Double Up" button. You can choose to gamble the whole amount or just a half of it. All you need to win is choose one heads or tails since this is a coin toss gamble feature. Correct guess will result in a win which you can either collect or gamble further, and the wrong guess will cost you the whole amount, and you will be taken back to the base game.
