Jackbox Pearl Upgrade RTP (95.07%), house edge & 500-spin session math
Jackbox Pearl Upgrade by SwinttPremium returns a published 95.07% RTP (4.93% 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 SwinttPremium release stands at -0.34 percentage points against the 95.41% studio average across 137 RTP-published titles (rank #93 of 137).
