Jack Potter Halloween RTP (95.42%), house edge & 500-spin session math
Jack Potter Halloween by Onlyplay returns a published 95.42% RTP (4.58% house edge) across a 5×3 / 5×4 HTML5 video grid layout and calls for a 250x–350x bankroll buffer in C$ at Here2Win Casino (here2win.com.au).
This Onlyplay release stands at -0.15 percentage points against the 95.57% studio average across 126 RTP-published titles (rank #70 of 126).
