Vault Blast Hold and Win RTP (studio benchmark), house edge & 500-spin session math
Vault Blast Hold and Win by OctoPlay benchmarks against the verified 95.50% studio average RTP (4.50% house margin across 34 titles) and suits a 100x–150x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Vault Blast Hold and Win does not carry a standalone RTP on its source sheet, so Grizzly Slots cites the verified studio distribution instead of guessing. The slot runs on a 5×3 video grid (with Hold & Win bonus board) layout, and its variance profile fits a 100x–150x unit-stake reserve when playing Vault Blast Hold and Win in C$ at Here2Win Casino (here2win.com.au).
