Open Vault RTP (studio benchmark), house edge & 500-spin session math
Open Vault by Fa Chai benchmarks against the verified 96.33% studio average RTP (3.67% house margin across 6 titles) and suits a 150x–200x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Open Vault does not carry a standalone RTP on its source sheet, so Boreal Slots cites the verified studio distribution instead of guessing. The slot runs on a 5×3 / 5×4 HTML5 video grid layout, and its variance profile fits a 150x–200x unit-stake reserve when playing Open Vault in C$ at Here2Win Casino (here2win.com.au).

Boreal Slots keeps Open Vault on a Canadian host so the wording stays in Canadian English: slot, player, C$. The Australian catalogues use their own wording on purpose. Same brand on the button, Here2Win Casino, different page.

Interac, cards and the C$ balance belong to the Here2Win Casino account you reach from the button. borealslots.com only publishes the catalogue. The page can name the rail.

18+. Boreal Slots is a catalogue for adults in Canada. Gambling can harm.
