Book of Lady RTP (studio benchmark), house edge & 500-spin session math
Book of Lady by Endorphina benchmarks against the verified 96.20% studio average RTP (3.80% house margin across 14 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Book of Lady 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 classic video grid layout, and its variance profile fits a 200x–250x unit-stake reserve when playing Book of Lady in C$ at Here2Win Casino (here2win.com.au).

|---|---|---|---|---|

| 250 spins on Book of Lady (C$1/spin @ 96.20% RTP) | C$250 | C$240.50 | C$9.50 | ~68–83 |
| 500 spins on Book of Lady (C$1/spin @ 96.20% RTP) | C$500 | C$481.00 | C$19.00 | ~135–165 |
