Page updated July 2026
Jack, from Wicked Games, takes on one of online slots' more macabre subjects — the unsolved Victorian murders long attributed to "Jack the Ripper" — and builds a six-reel, four-row, 50-payline game around it. It's a low-volatility title, giving it a steadier, more accessible rhythm than the grim subject matter might suggest.
The action unfolds on the back of a coach rumbling along a moonlit Victorian street, with a menacing nighttime London backdrop setting the tone throughout. It's a competent, if fairly restrained, take on the theme — atmospheric rather than graphic, and more concerned with mood than shock value. Ten-to-Ace royals make up the lower-value symbols, while five character-based icons carry the higher payouts, and wilds appear on every reel except the leftmost, substituting for anything but the scatter.
Jack returns 96.1% to players over the long run, a solid figure that sits comfortably above the typical mid-90s benchmark for online slots. That's a genuinely encouraging number for a game that otherwise keeps its volatility low.
Wicked Games has rated Jack as low volatility, or 1 out of 5 on its own scale, which points to frequent, smaller wins rather than rare, dramatic ones. It's a game built for a steady, drawn-out session rather than sudden swings, which suits players who prefer their bankroll to move gradually rather than in big jumps.
The ceiling here is 1,500x the stake, a moderate but respectable cap that fits the low-volatility design. Standard stakes run from 0.25 up to 500 per spin, and there's an ante bet option that multiplies the wager by 1.4x in exchange for improved odds of triggering the free spins round — a useful lever for players wanting to push their luck a little harder without switching games entirely.
Jack won't overwhelm you with elaborate visuals, but it delivers a competent, atmospheric take on its grim subject matter with a genuinely solid RTP and a gentle, low-volatility pace that keeps sessions moving steadily. The ante bet option adds a nice bit of flexibility for players who want more from the free spins feature.
