Book of Madness RTP (studio benchmark), house edge & 500-spin session math
Book of Madness by Gamomat benchmarks against the verified 96.12% studio average RTP (3.88% house margin across 8 titles) and suits a 100x–150x stake buffer in NZ$ at Here2Win Casino (here2win.co.nz).
Because the source card for Book of Madness omits an individual percentage, this Gamomat release is benchmarked against the studio's published range (96.11% to 96.14%). The pokie runs on a 5×3 classic video grid layout, and its variance profile fits a 100x–150x unit-stake reserve when playing Book of Madness in NZ$ at Here2Win Casino (here2win.co.nz).

|---|---|---|---|---|
