Disco Spins was released by NetEnt back in 2013 and the game was discontinued in 2018.
The game used a very colorful disco theme with 5 different dancing people, disco balls and standard card symbols.
It came with 5 reels, each 3 symbols high and 25 paylined.
The way wild symbols would appear was pretty cool. The dance floor (the spots below the symbols) would light up in one of five colors. If the dancer on that spot was the same color, it would turn wild. This way you could get up to 8 wilds per spin.
If you got 3 or more scatter symbols you could pick between 2 different free spins features.
As I mentioned above, the game got canceled in 2018, after 5 years being online.
I guess the main reason was just popularity. I do think it was a good game with a not that overused theme and I did enjoy the game when it came out.
