What this pokie is
Mottle Fen writes the Big Bad Bison entry for this host. Big Time Gaming made it. Here2Win Casino is where it is played. The stake shows as NZ$.
Mottle Fen keeps the New Zealand page for Big Bad Bison on its own host. Kiwi players get pokie, NZ$ and POLi named in this copy, in this order. The play button still ends at Here2Win Casino.
Payments people in New Zealand already use, POLi among them, are handled inside the Here2Win Casino account. mottlefen.org never asks for them. The page can name the rail.
Studio
If the only question was who built Big Bad Bison, the answer is Big Time Gaming. Here2Win Casino does not either.
A second Big Time Gaming pokie from this list is Danger High Voltage 2 Megaways.

Big Bad Bison RTP (96.58%), house edge & 500-spin session math
Big Bad Bison by Big Time Gaming returns a published 96.58% RTP (3.42% house edge) across a 5×3 / 5×4 HTML5 video grid layout and calls for a 250x–350x bankroll buffer in NZ$ at Here2Win Casino (here2win.com.au).
This Big Time Gaming release stands at +0.15 percentage points against the 96.43% studio average across 72 RTP-published titles (rank #17 of 72).
