50 Dolphins is an underwater, aquatic-themed slot machine with 5 reels and 50 paylines that was developed by the Australian-based Ainsworth slot machine company. The reel symbols include sea shells, treasure chests overflowing with gold, oysters filled with pearls, sailing ships, and of course, beautiful blue dolphins. This watery themed slot game made its online debut in May 2013.
The smallest coin denomination is 0.01, and with 50 paylines, the maximum bet available is 625 coins. This game also offers players the option to gamble after each win, guessing the card colour or the card suit to double or quadruple the win. The auto play feature is also available on 50 Dolphins Slot by Ainsworth.
Wilds and Scatter Symbols
The Dolphin Wild symbol is the main symbol on this game. The Wild symbol substitutes for all other symbols, except for the Scatter symbol, to complete winning combinations.
The Scatter symbol is represented by the Dolphin Medallion symbol. The Dolphin Medallion is the gold coin with the dolphin engraved on it. This pays 100x the total spin wager amount for landing five, 10x for 4 and 2x for 3. This scatter is also the trigger for the Free Spins bonus round, which is the financial objective of this slot machine. The Free Spins bonus round is activated when players hit three or more of the Scatter symbols anywhere across the reels during regular gameplay. The reward for achieving this is an immediate reward of 10 free spins. All wins achieved during the free spins are multiplied by the bet-line value. An additional 5 free spins is triggered if three or more scatters appear during the free spins. During the free spins the Wild symbol can appear as Stacked Wild symbols on reels 2, 3 and 4, markedly increasing the chance of winning some of the larger prizes on 50 Dolphins Slot by Ainsworth.
Of the other reel symbols, five sailing ship symbols produce a 1000 coin jackpot, although the other symbols such as the treasure chest, pearls, tropical fish and shells also reward players with jackpot payouts.
The graphics and the animations in 50 Dolphins Slot by Ainsworth are very rich and the deep blue hues of the background with the effect of the sun shining from above the waves create an aquatic atmosphere. The dolphin Wild symbols, which are stacked, have a special jumping animation when they form part of a winning combination. The background sounds are standard Ainsworth fare, clicking noises as the reels stop and short tunes which vary depending on the size of the win.
The jackpot payout in 50 Dolphins Slot by Ainsworth is not particularly high, yet this slot machine has a comparatively high payout rate. The reward system is considerably enhanced by the Stacked Wild symbols. These dolphins cover the entire reel when they appear, and this considerably improves the jackpot payout rate, with several wins being likely at the same time – a function of the 50 paylines. This is what changes 50 Dolphins Slot by Ainsworth into a high payout slot machine with an avid online following.
