Gates of the Underworld RTP (studio benchmark), house edge & 500-spin session math
Gates of the Underworld 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).
Gates of the Underworld does not carry a standalone RTP on its source sheet, so Klondike Reels cites the verified studio distribution instead of guessing. The slot runs on a 6×5 scatter grid layout, and its variance profile fits a 100x–150x unit-stake reserve when playing Gates of the Underworld in C$ at Here2Win Casino (here2win.com.au).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |

What this slot is
Klondike Reels is a poor place to look for a rush and a fair place to look up Gates of the Underworld. The studio is OctoPlay. The casino is Here2Win Casino. The stake is C$.
This title sits with the video slots in the Canadian section of the catalogue. City is not a setting inside Gates of the Underworld. What you set is the stake, and you set it at Here2Win Casino.
If you only needed the studio, it is OctoPlay. If the fact list has no RTP, there was nothing honest to put there. The rest of the OctoPlay slots are one click away on the provider page.
The same studio page names Break the Pumpkin Bank and then Turbo Diamonds.
