I have played 50-100-200-300-... spins and was waiting for those wins that I had to be taken back by this slot. On the contrary, this slot continued to give other wins. And even if there were not huge wins ever, I never lost too much and after 300 spins I had about 20 Euro extra.
There are many slots whose theme is the submarine life and this is one of them. A soft music accompanies the slot spins and there is no doubt this game is more pleasant than all the World Match slots that have played so far. In a way you can say that the wins remain the same throughout all the game play and here there are no ongoing series of dozens of losing spins. The extra wins are brought by the Free Spins and the Bonus Game, a Bonus Game especially nice when you choose with a magic stick 6 fish from an aquarium. There are also fish that do not bring anything (an old defect of these slots) but some other fish are paying nice.
I admit that I was expecting to find a weak slot, unattractive and avaricious. Instead I had a nice and giving game. Perhaps I will come back from time to time to stop playing at one slot from World Match chosen randomly.
