Great Reef

Great Reef is an adorable video slot from TopGame housing an underwater theme, where stylish graphics and realistic sound effects create a unique atmosphere on the reels. Rolled out in April 2014, the five reel twenty-five line game has made a real splash in the online gaming market, which is not that surprising given the presence of a thoroughly impressive bonus round that awards up to 33 free games at x6 multiplier.

Apart from Sharky, who will award a win even for two matching icons on a payline, you will need at least three identical symbols on any active line starting from the leftmost reel for a win. The payline scheme can be seen under Game Rules in the Paytable. The game supports a plethora of options located below the reels, including Bet Max, Autoplay, Fast Play and Gamble.

The Captain Wild will substitute for all non-feature icons to complete winning combinations, but it does not pay out on its own. Meanwhile, Gamble feature can be used after every winning spin of the reels, with players guessing whether the next card will be red or black for an opportunity to double their win. Gamble limit stands at either 500x bet or five cards.

Betting starts at $0.01 which is the smallest coin denomination and players can wager up to $5 per single payline. Maximum 25 lines are activated by default but you can also amend the number of active paylines if you like. Trigger the Fast Play option if you want your bets to be settled faster and choose up to 1,000 autoplay spins.

Payouts in the base play is one area where Great Reef certainly does not excel, but with maximum coin jackpot standing at mere 500 credits, chances are those winning combinations will occur more frequently, which is enough to suggest this game falls into the low-volatility category of video slots.

While experienced seaman and Oyster act as the two special icons, adorable shark aptly named Sharky leads the way when it comes to regular game symbols that also include sea turtle, clownfish, seahorse and starfish. As that is usually the case, low-value icons are reserved for playing cards Ace through Ten.

Obtain at least three Oyster symbols scattered anywhere on the game screen and you will unlock the Pearl Hunter Bonus round. You will immediately receive a number of free games and starting multiplier, while you get two more chances to secure up to 33 free games and up to x6 multiplier by choosing two of five pearl oysters. Bear in mind that two, three, four or five Scatters in any position award an instant win of 2x, 5x, 20x and 100x total bet.
