Mystery Jack Deluxe by Wazdan is a 3-reel, 27-payline slot with a Western desert theme and a 96.49% RTP. The layout uses a compact 3x3 grid, with classic symbols including 7s, BARs, fruits, bells, and themed Mystery Jack icons. The game also shows a Wild symbol, which substitutes for most other symbols, and a Scatter symbol linked to the bonus feature.
The demo version lets players play for free and practice before playing for real money. According to the game details, three or more Scatter symbols trigger 9 Free Spins, while the Mystery symbol can award a mystery prize when several appear together. A double-or-nothing gamble feature is also included, allowing a win to be risked for a chance to double it.
Bet settings range from 0.1 to 100, with autoplay and max-bet options available in the interface. The slot combines a Western cabinet style with clear control panels, making its main mechanics visible before starting a paid session.
