Set on the outskirts of a North American canyon, the Bison Moon Ultra Link and Win slot has a background that will be familiar to many players. Half of the screen is occupied by a desert landscape, featuring rocky formations on either side, while the other half is filled with a cloudy sky.
The board appears on top and comes with a total of 5 reels and 25 paylines, all of which can be covered with a minimum stake size of 0.10.
This title was created by Northern Lights Gaming, a provider that does a lot of work with Microgaming. It's this partnership that created the original Bison Moon, alongside other popular online casino slots like Tiki Tiki Boom and Storm to Riches, amongst others. Northern Lights Gaming have a flair for graphic design and as a result, their releases tend to stand out from the crowd on appearance alone!
The standard symbols in Bison Moon Ultra Link and Win are the regular J, Q, K, and A icons that can be found in many other slots online. In order of desirability, premium icons consist of a raccoon, an eagle, a wolf, and a bear, which can award players with up to 7.50x, 10.50x, 15.00x and 25.00x their stake size, respectively.
Bison Moon Ultra Link and Win also has three different special icons, one of which is a wild symbol, shown as a bison. Of course, this comes with the ability to substitute for any of the aforementioned icons as part of a combination. There are also fixed value and scatter symbols, displayed as red and blue moons, which have their own corresponding bonus modes!
First up in this section is the 'Bison Stampede' modifier, which can trigger at random during any spin. A variety of bison icons will be added to the reels, with each one transforming into a wild, a fixed value, or a scatter icon. The reels will then spin as normal.
The 'Ultra Link and Win' mode is next, which can be triggered if six or more fixed value moon symbols appear simultaneously. Players are then taken to a new grid before the triggering symbols are carried over and three respins are awarded. During this mode, only fixed value moons and jackpot moons can appear, with mini, minor, and major variations sitting at 50x, 150x, and 750x the stake size, in that order.
Every time a new moon symbol lands, the number of respins will be reset to three. It's also possible for players to unlock new rows, should enough sticky symbols be present on the board. The round will end when no more respins remain, at which point all values on the board will be totalled up and awarded to the player. It's also worth mentioning that this round can end by filling all positions on the board, in which case the player will be awarded with the mega jackpot, sitting at 10,000x their stake size.
The last bonus mode is the free spins one, which can be triggered if three scatter icons land simultaneously. Again, players will be taken to a new grid and with this one, the middle three rows combine to showcase giant symbols, which can be any icon in the game. If the jumbo symbol is a scatter, ten more spins will be awarded. Players can also trigger the 'Ultra Link and Win' bonus round from within the free spins mode.
Bison Moon Ultra Link and Win have a somewhat basic appearance. However, it's the bonus features that set it apart from other online slots. The Ultra Link and Win mode is perhaps the most interesting, with the maximum potential winnings for the round sitting at 10,000x the stake size.
