The graphic of the game is on a high level and it has some nice animations. The background music is very soothing and calming so you can spend hours playing this slot. I have to point out that the base play can be a bit boring at times and unlike some other slots 5 of a kind wins come rarely in the base play. Most of the time it can just eat up balance until you hit a bonus round and a chance to win something back or more. The only feature in the base play or the bonus round is the expanding wild which can land on reel 2 or 4 or both. This can provide some nice win during base play or in the bonus game.
If you get 3 scattered pearls the free spins bonus is triggered and you have a choice to make. You can choose from 10 free spins with a random multiplier which can go up to 10, 15 free spins with a random multiplier up to 7 and 20 free games with a random multiplier up to 4.All of these choices can produce nice wins but I tend to choose the 15 free spins. The reason is simple. The max multiplier of 7 comes every 3-4 spins so with 15 free spins there is a greater chance to hit a nice win on the max multiplier.
On my last session with this game I was lucky enough to get the bonus round on a high 1.25 bet and managed to win about 140 euros from the free spins.
