Not really, no. As you can see from the relative paucity of slots titles displayed on this page, the “shifting reels” feature is confined to the realm of a few bigger-name casino game software designers/producers. This is definitely one of those features that, once tried, is often sought out again, so we can probably expect the popularity of this fairly obscure feature increase.
Any slots player who has indulged in a game with “1,024 ways to win”, stacked wilds, extra symbols or any other feature that would seem to make wins inevitable, only to find that the non-paying combination in a slot machine will *always* well outnumber the victories, would certainly appreciate shifting reels in their favorite slots, if only to give the illusion of bonus wins.
However, the advantage of shifting reels is obvious to the seasoned slots player: Any shift of a reel leftward is automatically more likely to increase the chances of winning, particularly in a “243 (or more) ways” slot. Think about it: Wins in a 5-reel slot game are dependent upon getting matches within the first three reels. A reel shifting from the fourth spot to the third – or middle – turns a probably-irrelevant reel of symbols in a potential payer. And shifting wilds in reel 2 over to that left-most reel is a boon most of the time.
Of course; we believe that, in 5-reel video slots, the more features, the merrier!
