5-Line Bonus 21 RTP (studio benchmark), house edge & 500-spin session math
5-Line Bonus 21 by Greentube benchmarks against the verified 95.05% studio average RTP (4.95% house margin across 135 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for 5-Line Bonus 21 omits an individual percentage, this Greentube release is benchmarked against the studio's published range (92.13% to 96.45%). 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 5-Line Bonus 21 in C$ at Here2Win Casino (here2win.com.au).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |

| 250 spins on 5-Line Bonus 21 (C$1/spin @ 95.05% RTP) | C$250 | C$237.63 | C$12.38 | ~68–83 |
| 500 spins on 5-Line Bonus 21 (C$1/spin @ 95.05% RTP) | C$500 | C$475.25 | C$24.75 | ~135–165 |
