Stacks Of Jacks

Overview

This version of Stacks Of Jacks comes from BulBul, a separate studio from the Gamomat release that shares the same name, and it arrived on the market a little later, in May 2026 compared with Gamomat's March release. Same title, same general "stacked card" premise implied by the name, but a genuinely different build from a different developer, so it's worth treating this as its own release rather than a reskin.

What's Confirmed

BulBul's Stacks Of Jacks carries the identical 96.16% RTP figure and the same medium volatility rating as its Gamomat namesake, which is a solid, above-average return by industry standards. Beyond that, the confirmed data for this particular listing is limited — no verified figures for reel count, paylines, maximum win or stake range have been published yet for this build.

Why the Overlap Isn't a Concern

It's not unusual for two studios to land on similar names or ideas independently, particularly with a straightforward, evergreen concept like stacked Jack symbols. Because BulBul is a different developer to Gamomat, expect the visual style, sound design and possibly the bonus mechanics to differ even if the underlying premise and headline RTP look alike on paper. Treat the two as genuinely separate games worth trying individually rather than assuming one is simply a copy of the other.

RTP and What to Expect

At 96.16%, this version returns a genuinely competitive figure over the long run — better than a large share of the slots currently in circulation. Medium volatility suggests a fairly even mix of smaller, regular wins and occasional bigger hits, rather than long dry spells punctuated by rare huge payouts.

Verdict

BulBul's take on Stacks Of Jacks shares its headline numbers with the Gamomat version but stands as its own release from its own developer. With max win, paylines and betting range still to be confirmed, the sensible move is to fire up the free demo at johnessyslots and check the in-game paytable for the full mechanical picture before playing with real money. Comparing the two versions side by side in demo mode is also a good way to spot the differences in presentation and pacing once you've had a chance to try both.
