Paul spent plenty of time in arcades up and down the UK discovering all of the best fruit machines and watching them grow into the incredible online slots we see today. He still loves the basic format but also has a soft spot for games with big bonus rounds that progress as you play. Immortal Romance is one of his favourite slots of all time.
