Spooky Jack by EGT Digital is a Halloween-themed slot presented in a 3x5 layout with 20 fixed paylines. The demo version lets players play for free and practice before playing for real money. The reel set combines cartoon-style symbols such as ghosts, bats, cats and skulls with low-value card-suit icons, while the background uses a graveyard scene with glowing pumpkins and dark blue lighting.
The main special feature is the expanding Wild Pumpkin, which appears on the second, third and fourth reels and substitutes for regular symbols. Two scatter symbols are included: a ghost scatter that can land on all reels, and a candy scatter that appears on the first, third and fifth reels. The game also shows four progressive-style jackpot meters labeled Grand, Major, Minor and Mini, updating in real time.
Winning combinations are shown with highlighted lines across the reels, and the interface includes a Gamble feature after a win, where players choose red or black on a card screen. Controls for spin, speed, bet options, sound and full-screen mode are placed around the main grid, making the demo version useful for learning the game structure before playing for real money.
