The theme follows the history of rock music in the last century. So, here you have a symbol with Elvis Presley, Paul McCartney as a representative of the Beatles, then there is a symbol of Jimi Hendrix, a symbol of the American singer of the band Kiss, then a symbol that reminds me of the singer of the British punk band The Exploited - Wattie Buchan and so we came to Guns N 'Roses and the symbol that reminds of the band's singer Axel Rose.
By a well-tested recipe, when it comes to the older Rival games, also here you have two bonus features. More precisely, you have a classic bonus round and a free spins feature. Three + symbols with a drums activate the Free Spins feature. Three or more symbols with Elvis will activate the bonus round. Also the expanding wild symbol here can help you to get to the big wins.
Once I played here quite often and also I had some decent wins. However, the last time when I played here I've lost a lot of money. Even though my sense was telling me that I should move on to another game I've kept making spins and spins here, hoping for some big wins that will turn around the things in my favor. Playing with a bet of 0.4 euros for about 1 hour that I spent here, I lost more than 150 euros. But no matter of that, this is a game that deserves high score. So, for the Rock On I'm going to give 8 of 10 possible stars.
