Book of Mystery RTP (studio benchmark), house edge & 500-spin session math
Book of Mystery by JDB Gaming benchmarks against the verified 96.34% studio average RTP (3.66% house margin across 2 titles) and suits a 150x–200x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for Book of Mystery omits an individual percentage, this JDB Gaming release is benchmarked against the studio's published range (96.19% to 96.48%). The slot runs on a 5×3 classic video grid layout, and its variance profile fits a 150x–200x unit-stake reserve when playing Book of Mystery in C$ at Here2Win Casino (here2win.com.au).
