About this Slot
Junkyard Jacks from Midnight Studios is a humor-themed 5x5 slot with 20 paylines, 96% RTP, high volatility and a maximum win of 15,000x.
Wilds expand to fill entire reels, replacing regular symbols only. Sticky Wilds remain locked in place across spins, and Wild Multipliers boost payouts on winning combinations featuring them.
Three Scrap scatters trigger Jacks Bonus, awarding 8 free spins. Random expanding Wilds appear during the bonus round, while locked Wild reels stay active throughout. Scatters do not land during free spins, and Jacks Bonus cannot retrigger.
Double Jack costs 25x per spin and keeps two Wild reels locked until you switch off the feature. Double Jack does not automatically start a spin when activated and cannot run alongside Extra Chance.
Jacks Bonus can be bought directly for 100x bet, granting 8 free spins with random expanding Wilds and locked reels active as standard.
Super Jacks costs 300x bet and awards 8 free spins. This option guarantees a Wild on the first spin, and Wild reels remain locked throughout the entire feature.
Extra Chance increases the cost of each spin by 1.5x stake and doubles your chance of triggering free spins. It does not change payline values and cannot run alongside Double Jack.
