The game has a number of low-volatility traits going for it: The game’s been out for some time, but IGT re-released it as part of its more modern reels games, ensuring it will live on for quite some time to come.
However, an older, but also fun, one comes from IGT in the form of the physical (or virtual) 3-reel Triple Double Diamond free games. I recently wrote about Ainsworth’s Quick Spin slot machine, which is a great modern low volatility play.
