The benefit of RNG is that is isn’t affected by human error, like being a poor shuffler or weak ball spinner. Now in relation to online slot “machines,” we know there are no wheels, or reels, inside of the mobile gambling software. Today, most slots are classified as either 3-reel, 5-reel, 7-reel, multi-reel, etc. As stated, when playing online there are no actual reels. Now they simply display a series of images on a “virtual” reel.
