The theme is opera and it's quite original for a slot game. At this moment I can’t remember of any other slot games with theme as this. I like the design, the animations and the sound effects in this game.
Also, when it comes to the features creators in Rival were quite original here. The first and the main feature in this game is a free spins feature. For the duration of the free spins you can also come to two other features that are called here the Opera Night Super Round Feature. The first of them is a bonus feature. If it happens that during the free spins you come to this feature, it is almost guaranteed that in the free spins you will have wins which are bigger than 100 x bet. Another feature which you can come to in the free spins is called Drop feature. Here, you will not be so well paid as in the bonus feature, but all that together contributes that to this game to be very interesting and fun. Otherwise, depending on the number of scatter symbols you can get 8-64 free spins as you get for 5 scatter symbols.
As I already wrote, at the beginning of my gambling career I played this game often. But it's been a long time since I played the Opera Night last time, so before I started with writing of this review I have played for fun just to remember of the atmosphere and the rules in this game. Besides the fact that Opera Night is not my choice lately, I think it deserves a high rating. For Opera Night I give 8 out of 10 possible stars.
