A Snowy Herd Built for Microgaming's Link and Win Grid
The animal theme here isn't subtle: heavyset bison figures anchor the reels, set against a cold, moon-lit palette that matches the "Bison Moon" name. Microgaming built this one as part of its Ultra Link and Win family, so the grid itself carries the branding as much as the herd does — it's a title designed around a locking-symbol format rather than a straightforward payline spin.
How It Plays: High Volatility on a Locking Grid
Bison Moon Ultra Link and Win carries a high-volatility rating, which means the gaps between meaningful hits tend to run longer than on a steadier title, and the swings when they land can be bigger. I've grouped it with the rest of the quick-fire shelf in the Here2Win Casino slots lineup, where the full pace scale explains how high, medium and low volatility compare across all twenty titles rather than repeating that ground here.
What the Grid Delivers: Jackpot and Bonus Rounds
Two features are confirmed for this title: an in-game jackpot and bonus rounds, both tied to the Ultra Link and Win grid that gives the game its name. That's the honest extent of what I can confirm about the mechanic — I won't invent trigger counts or respin conditions that aren't stated, since a themed grid alone doesn't tell you the exact rules underneath it. If a jackpot-sized win does land, it moves toward your balance the same way any other slot win does, and from there the path runs through the same Withdrawal process as any other cash-out.
RTP and Provider Credit, Plainly Stated
Bison Moon Ultra Link and Win returns 94.13%, credited to Microgaming. Set against this catalogue's median RTP of 96.045%, that figure sits below the middle of the pack, and it's currently the lowest RTP among the titles I've written up for Here2Win Casino. That doesn't make the game unplayable, but it's worth knowing going in, especially alongside a high-volatility rating that already stretches session length.

Bison Moon vs. 108 Heroes Water Margin: the Other Microgaming Pick
Here2Win's slot catalogue only carries two Microgaming titles, so it's a natural pairing. 108 Heroes Water Margin also runs high volatility, but its RTP sits at 96.06% — noticeably closer to the site median — and it swaps the jackpot mechanic here for a Bonus Buy route into its feature instead.
| Detail | Bison Moon Ultra Link and Win | 108 Heroes Water Margin |
|---|---|---|
| Provider | Microgaming | Microgaming |
| RTP | 94.13% | 96.06% |
| Volatility | High | High |
| Features | In-game jackpot, bonus rounds | Bonus rounds, bonus buy |
My honest read: if you want a grid built toward a jackpot ceiling, Bison Moon is the one to load; if you'd rather choose exactly when a bonus round starts, 108 Heroes' Bonus Buy route and its slightly friendlier RTP make more sense. Either way, both sit inside the same operator context — worth a look at is Here2Win Casino legit before either one, if licensing and payment questions are still open for you.
