Features Jeff & Scully by ELK Studios is a 7-reel, 7-row slot with the Area Win mechanic, where wins are formed by matching symbols in the corners of a rectangular area. The game uses multipliers, wilds, instant pay coins, sticky redrops, and symbol swaps, with a stated top potential of 10,000x bet. RTP is shown in the 94% range, with medium-high volatility.
Players can open the demo version to play for free and practice before playing for real money. The base game includes the Jeff feature, which pays an area win for each symbol within the winning area, and the Scully feature, which swaps symbols to create additional area wins. X-iter modes are also available, offering different entry points into bonus features, including a Super Bonus mode.
Three Bonus symbols trigger the bonus game, where multipliers and instant pay coins remain sticky during the free drops. Four Bonus symbols activate the super bonus game, in which sticky multipliers and instant pay symbols increase in value with each new free drop.
