**NIGHTMARE SQUAD** immerses players in a haunted forest on 5 reels and 20 paylines. Collect Frankenstein, Casper, Bloody Mary, and Fester for wins, with Fester acting as a Wild to complete combinations. Landing 3 or more Tombstone Scatter Symbols triggers **10–30 Free Spins**. During Free Spins, one or more symbols may turn into **Extra Wilds**, replacing all symbols except Scatter and Mystery Symbols for bigger payouts. Mystery Symbols activate a random **Mystery Bonus**, awarding prizes within a min–max range based on the triggering bet. All bonus winnings are added to the global Free Bank and credited to the player’s balance at the end of the bonus round.
