Book of Ishtar RTP (studio benchmark), house edge & 500-spin session math
Book of Ishtar by Holle Games benchmarks against the verified 95.43% studio average RTP (4.57% house margin across 26 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for Book of Ishtar omits an individual percentage, this Holle Games release is benchmarked against the studio's published range (92.40% to 96.23%). The slot runs on a 5×3 classic video grid layout, and its variance profile fits a 200x–250x unit-stake reserve when playing Book of Ishtar in C$ at Here2Win Casino (here2win.com.au).
