My point is that the computer RNG virtual reels are not limited to the actual positions on any reel. On a virtual, computer machine, the RNG could give you any number of 'stops' such as:
On a mechanical slot your combinations would be
You have a two reel slot with two 'stops' or positions on each reel. this actually gives you more results that you could get from just the actual reel positions. In the past, before computers, winners were determined by the actual reels, but today the RNG determines which reel positions show based on millions of possible reel positions instead of the actual count of 'stops' on a reel. What you are missing, however, is that today's modern slot machines have reels that only mimic the 'virtual reels' of the random number generator. different colors = different win amounts. but the 7s on the reels are different colors and you must match up three 7s of the same color to get a winner. The machine I am most familiar with is 'all 7s' and on every spin you will get three 7s across. but the symbols showing across must match a cerain combination to get a payout. Im not sure if this will answer your question but there are slot machines with a symbol on every line and every result will show three symbols across.
