Super Nova
Super Nova (supernovacasino.com) is a space themed casino with travel destinations instead of promotions. Special offers for new players include 300% slots match as a gift and 100% cashback on first deposit. All of the website navigation for Supernova is planet and moon themed, some of their slots include Japan-o-rama, Heavyweight Gold and Reel Crune Bank Heist.
