Jack Sullivan

Slots Writer

Jack has played online slots for over a decade and has a soft spot for high-volatility titles and Megaways. He writes about how free spins and bonus buys really play out, which features have substance and which are just show. Before every piece he puts the slot through a long run in demo mode. His goal is to give players an honest read before they stake real money.
