Cosmic Voyager is a slot available on any device, from desktop to mobile, favouring those who like a challenge. Players select stakes from a wide range of superslot pgslot options starting at 10 p/c rising to £/€100 per spin. It won't be plain sailing through the stars due to the highly volatile math model, something that goes hand in hand with the all or nothing nature of the expanding symbols feature as you will see. As mentioned, full-screen wins are certainly possible, and indeed the chance of them occurring is enhanced by the way features function. RTP is more down to earth, in a good way, its 96.14% figure hovering slightly above average.
