The Ghost Captain substitutes for all symbols except for Ghost Ships, which serve as scatters. Ghost Ship wins are multiplied by total bet. With the appearance of either the Captain or Ship, a Ghost Captain wild may fill the entire reel that it appears on. The eerie Ghost Captain comes to life on a winning spin, popping out and firing a pistol straight out of the screen.
The Free Games feature is triggered by 3 or more scattered Ghost Ships, awarding 2 free games per Ghost Captain or Ghost Ship onscreen.

Loch Ness Loot is the perfect option when you’re in good spirits – or when you need something to lift your mood.

The game’s water-themed symbols include a rowboat, a misty Polaroid photo of the Loch Ness Monster, and a sack of gold coins lying at the bottom of the lake.
The substitute and scatter symbol rules are simple. Lochie substitutes for all other symbols on the reels, and that includes the scattered Treasure symbols. When a Treasure symbol appears on a winning spin, the win is multiplied by the total bet.
The most intriguing aspect of Loch Ness Loot is the extra features. The standard Free Games feature is triggered by 3 or more scattered Treasures, appearing from Left to Right.

Like many other aquatic slots, Megaquarium also has an underwater treasure symbol, gleaming inside of an open wooden chest.
One element of Megaquarium that makes it stand out among slots games is its lack of scatters.

It even includes an Extra Game symbol, which enhances the Mega Game feature even more.
The bonus symbols for these features appear on set reels, and they often create a waterfall effect that leads to wave after wave of extended bonuses – that means a seemingly never-ending supply of free games, increased wild Clown Fish appearances, prize multipliers, and randomly awarded prizes of anywhere from 2 to 500 times your bet.

Rex, the substitute symbol, is a comical dog-like shark with a collar and its tongue sticking out.

• Scatter Symbols: Galleon and Treasure Chest
• Wild Symbol: Skeleton Key
• Jackpot: Local Progressive, Symbol Driven
Pirate Isle opens with a fun 3-dimensional opening scene with an animated pirate, much like what you’d find in an advanced video game. The rest of the game follows suit, complete with all the familiar pirate ship symbols: the mischievous monkey, the parrot, menacing pirates, cannon, steering wheel, black pirate flag, treasure chest… the list goes on.
The Skeleton Key is a grouped Wild – it normally appears on reel 3, counts for all symbols excluding scatters, and doubles the prizes of winning spins. Pirate Isle has two scatter symbols: the Galleon and the Treasure Chest, both of which multiply wins by slot bet.
Pirate Isle one of the most involved slots games out there – if you consider yourself a gamer, this slot is essentially a video game in slot form. On a normal spin, 3 or more Treasure Chests trigger the Treasure Chest feature, which can award the player with up to a grand total of 300 free spins, a feature that’s practically unheard of! Treasure Chests lead to more prizes and picks, and a Treasure Map allows you to select a location to reveal a Treasure Chest, a Map, or a Ghost.

1. Shark School
• Volatility: High
• Lines: 50 Variable Paylines with all symbols paying from Left to Right, except scattered Schools, which pay any direction
• Scatter Symbol: School
• Wild Symbol: Teacher
• Jackpot: N/A
The Shark School theme is thoroughly developed, and the game has the visuals to match. Big block letters and symbols are reminiscent of those varsity jackets that you might remember from your days in school, and the five reels are flanked by two sets of school lockers on the left and right of the screen.
With its well-designed symbols, Shark School is one of the most detail-oriented slots games when it comes to establishing a complex theme – when you’re playing, it practically feels like you know these individual characters. There’s an orange fish wearing broken thick-rimmed glasses bound together with a piece of tape and peeking apprehensively out of a bed of coral, a sardine with a red backpack strapped to his back, a tough-looking shark with a fishhook nose ring and a menacing sneer on his face, and another shark lurking in front of some lockers with a baseball cap perched on his head.
The substitute symbol is the “Teacher,” an octopus wearing a graduation cap and shaking a test tube, and the scatter symbol is a traditional red-brick school building. The Teacher appears grouped on reel 1, standing in for all symbols including scatters. Scatter wins are multiplied by the total bet, but most exciting of all, 3 or more scattered Schools can trigger any 1 of 3 fun pick features: Swim Fishy Swim, Bad Sharky, and Don’t Eat the Teacher – each has its own special perks, including free games, re-spins, bonuses up to 200x the bet, and more.
Shark School is one of the rare games that, instead of a jackpot, features an abundance of features, exciting animations, and truly exciting bonus games as well as exciting ways to win. It’s a truly engrossing game that will make the time pass – or swim by at lightning speed.
