Fat Jack card on Fern Spins
Kiwi players can open the session page for Fat Jack pokie apart from this catalogue.
Fern Spins lists Fat Jack as a Silverback Gaming pokie for players in New Zealand, opened at Here2Win Casino. No RTP was on the source card, so this page does not borrow one from a similar game. The studio is the fact that is actually known.

Fat Jack RTP (studio benchmark), house edge & 500-spin session math
Fat Jack by Silverback Gaming benchmarks against the verified 96.06% studio average RTP (3.94% house margin across 11 titles) and suits a 150x–200x stake buffer in NZ$ at Here2Win Casino (here2win.co.nz).
Because the source card for Fat Jack omits an individual percentage, this Silverback Gaming release is benchmarked against the studio's published range (95.62% to 96.46%). The pokie runs on a 5×3 / 5×4 HTML5 video grid layout, and its variance profile fits a 150x–200x unit-stake reserve when playing Fat Jack in NZ$ at Here2Win Casino (here2win.co.nz).
