Microgaming and Gold Coin Studios have combined forces to bring this good-looking slot machine to PCs, iOS, Android, and Windows mobiles. It’s a relatively simple game, with basic, but potentially rewarding features and symbols such as playing card icons, diamonds, emeralds, and a cute dolphin.
This nicely animated creature is a wild symbol who helps to complete wins across the 20 lines; a scatter symbol leads to free games with extra wilds in play. The gamble option is an exciting feature and, with luck, you can boost wins several times over. Or you might lose the gamble and forfeit the triggering prize.
You can select from a wide bet range, which makes this a great game for inexperienced players looking to dip their toes into an underwater-themed game, as well as those players who like cute animals and classic bonus rounds. Check out gambling.com for top online casino bonuses to get started.
Novice players will find the Aquatic Treasures slots game very easy to set up, with just a few clicks on plus and minus buttons on the controls needed to find the ideal bet level. Options run from a minimum real money slots bet of 0.20 to 100 credits per spin, which is 0.02 to 5.00 on each of the 20 paylines.
Winning combinations come from 3 or more matching symbols across a line from the left. The 3 lines button to the left of the controls opens the paytable, where you see how much you win from each symbol. The least valuable “10” symbol pays 80x your line bet when it fills a payline. At the other end of the scale, the purple gem is worth a maximum of 750x.
Other useful control options include an automatic spins function, fastplay mode and the choice of playing across desktop and mobile platforms.
The smiling cartoonish dolphin is a wild and can act as all other symbols if needed. Every time it appears on a reel, it expands up or down to fill all 3 rows, and if more than one adjacent reel has the wild on it, it becomes one big symbol.
Two golden dolphins circling a pearl are the scatter symbol of the Aquatic Treasures slots game. Any 3, 4, or 5 in view will pay 2x, 5x, or 25x your total stake. If scatters appear on the first 3 reels, you also claim 8 free spins, and wild dolphins can help to trigger the round.
You’ll see extra wilds in play throughout the free games, so it should be easier to win prizes, and the feature retriggers with more scatters landing in any spin.
If you choose to gamble any win, either in the base games or free spins feature, a second screen opens where you see a gold coin. Make a guess on heads or tails and the coin flips. You double the win if you get it right and lose the prize for an incorrect pick.
Without the gamble feature, the biggest win possible is 375x your stake, or 37,500 credits if you have 100 on the triggering spin. That’s a relatively low multiple, especially from a game with a medium volatility such as Aquatic Treasures. Average returns are 96.03%, which is decent, but not outstanding at our best online casino sites.
The Aquatic Treasures slot is quite a basic game; we think it could have benefitted from more sea creatures. Expanding wilds and free games are popular features, and the option to gamble wins can lead to some decent payouts.
But the 375x maximum win isn’t much, especially when compared to games such as the Dolphin’s Gold online slot from iSoftbet. That one returns wins of up to 1,000x your bet. Dolphin’s Gold also comes with lots of cartoon fish, a similar stacked wild dolphin symbol, free games, and win multipliers.
It could be a better choice for experienced players, but if you like straightforward style and features, then you can check out the Aquatic Treasures online slot at our top Microgaming-powered casinos. Our top online slots sites all come with generous introductory bonus offers for you to collect.
