Costume Party RTP (studio benchmark), house edge & 500-spin session math
Costume Party by Rival benchmarks against the verified 96.17% studio average RTP (3.83% house margin across 15 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for Costume Party omits an individual percentage, this Rival release is benchmarked against the studio's published range (94.60% to 97.00%). 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 Costume Party in C$ at Here2Win Casino (here2win.com.au).
