About this Slot
UFOBoost features a space, gems and sci-fi theme, with an RTP of 96.02%, high volatility and a maximum win of 10,000x.
Matching symbols connect in groups to form clusters. When winning clusters clear, Boost Features trigger in sequence. Every 25 winning cluster symbols awards one Boost, with a maximum of five Boosts queuing per spin.
Three, four or five Scatters landing on reels 2-6 trigger Free Spins. Three Scatters award 15 Free Spins and one X1 symbol. Four Scatters award 15 Free Spins and two X1 symbols. Five Scatters award 15 Free Spins and three X1 symbols.
X1 symbols persist on the grid throughout Free Spins and move on every cascade refill. When an X1 symbol appears in a winning cluster, it gains +1 for each refill that occurs.
Every 100 cleared symbols during Free Spins awards an additional three Free Spins and one additional X1 symbol.
Bonus Buy allows direct purchase into Free Spins.
