Spring Queen RTP (studio benchmark), house edge & 500-spin session math
Spring Queen by Greentube benchmarks against the verified 95.05% studio average RTP (4.95% house margin across 135 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for Spring Queen omits an individual percentage, this Greentube release is benchmarked against the studio's published range (92.13% to 96.45%). The slot runs on a 5×3 / 5×4 HTML5 video grid layout, and its variance profile fits a 200x–250x unit-stake reserve when playing Spring Queen in C$ at Here2Win Casino (here2win.com.au).
