Astro Rumble RTP (studio benchmark), house edge & 500-spin session math
Astro Rumble by Bullshark Games benchmarks against the verified 96.25% studio average RTP (3.75% house margin across 11 titles) and suits a 200x–250x stake buffer in C$ at Here2Win Casino (here2win.com.au).
Because the source card for Astro Rumble omits an individual percentage, this Bullshark Games release is benchmarked against the studio's published range (96.15% to 96.31%). 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 Astro Rumble in C$ at Here2Win Casino (here2win.com.au).
| Session volume & entity | Total turnover | Theoretical return | House margin | Est. winning spins |
