Single line slots are slot machine games that have just one payline. A payline is the lineup of reel symbols that results in winning or losing combinations. Traditionally, slot games only had one payline. If you think of a classic slot with three reels, you’re thinking of a single payline machine.
Slot machine odds are a difficult subject unless you have some basic understanding of higher mathematics. Having said that, single line slot machines games are much less complex than today’s multi line slots, video slots, and other slot games variants.
If you want to learn how to win at slots, you need to wrap your head around some basics about the slot machine odds. Here’s a quick look at the math behind single line slots odds.
First of all, understand that slot machines games are usually weighted. That means that some symbols appear more often than others. Obviously, casinos want their slot machines games to pay out the top jackpots less often than smaller winnings. Single line slots usually weight the top jackpot so that each reel has just one “stop” for the top jackpot symbol. The odds of hitting that symbol on any single line of a slot are 1 in 64. That gives you odds of 1 in 262,144 to hit that top jackpot on a single line slot. Obviously, slot machines games with more paylines or larger jackpots will have more “stops” and the odds will be even longer.
Single line slots odds are an easy way to prove to doubters that slot machines games aren’t “fixed” or otherwise altered to payout at specific times and dry up at others. The odds of given slot games are literally built into the computer chip on the machine, or (in the case of old-fashioned mechanical slots) built into the mechanics of the game. That’s why casinos aren’t capable of instantly tightening up a machine if it is paying out “too much.” Casinos are in control of their slot games on a grander scale than a single win or loss here and there.
Single line slot machines games are becoming rare, except in smaller gaming venues or casinos where single line slots are kept to entertain people who may want to get a taste of old school gambling. Some online casinos even have single line slot games with autoplay, offering a product for customers not interested in the flashier and more expensive video or 3D slots.
