Ariana by Quickfire powered by Microgaming

Ariana by Quickfire powered by MicrogamingMicrogaming takes us on a deep-sea trip with Ariana, a beautiful mermaid. Explore the underwater world of a cove known for its starfish, sea horses, and corals, searching for sunken treasures. Surrounded by coral reef colonies, in the kingdom, the aquatic siren, with marvellous turquoise bright colours, the reels glide gracefully as if they are actually spinning underwater. The sound effects give a sense of awe and magic whenever the reels reveal a winning combination. You can make a splash with expanding symbols; during the usual and the Free Spins, you can take a peek at the bonus round re-triggers or meet another group of bountiful gorgeous marina species. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

Although expanding symbols are not a new concept, with the maximum payout of the 2015 released Ariana slot machine reaching up to 30 000 coins, RTP of 95%, you can certainly enjoy the Medium Variance, soft and dreamy gameplay. Try it now in the free DEMO version on this page. No registration or download is needed. 

Personal testers’ opinion

This is one of Microgaming’s games with decent graphics and relaxing sounds, where the developer focuses on the possibility of expanding symbols. Ariana expands anywhere on the reels, while the other expensive symbols only expand on reel 1. When they stretch on reel 1, all the other matching symbols in the field will also expand if they are part of a winning combination. 

Ariana slot often triggered the Free Spins during our tests, delivering an average winning of 157x bets in the bonus spins and 30x in the usual spins. It will help if you stay alert about the mood of the slot by observing the 3rd Starfish Scatter symbol. If you notice 2 Scatter symbols often appear in a row, without the important 3rd one, or if several empty/measly bonus games were rewarded, then it might be a good moment to change the slot. It is an indication of cold behaviour. According to the statistics, the chances to trigger the bonus feature here are equal to 0.77%, which means it should be initiated every 129th spin. But the slot is not very popular, so all the analytical figures might vary depending on the prize pool.
