A symbol that substitutes for other symbols to create winning combinations, like a joker in cards. Some wilds have multipliers or expand to cover reels.
Special symbol that pays or triggers features regardless of position on paylines. Usually triggers free spins or bonus rounds when you land 3+.
A jackpot that increases with every bet placed across the network until someone wins. Can reach millions of pounds. Small portion of each bet adds to the pool.
Bonus spins where you don't risk your own money. Can be awarded as a bonus or triggered within games. Winnings usually have wagering requirements.
