How many types of slots are there?

how many types of slots are there

Slot machines are in general the dominant money-maker in both land-based casinos as well as online ones. They have come a long way over the years and today you can find a wide variety of them. Here is a quick rundown of some of the slot types available for players.

Three-Reel Classic Slots

This is the original slot machine which was invented by Charles fey. You can still find plenty of these in casinos around the world but they are mostly for their nostalgic value. Newer and better machines are fast replacing the three-reels.

Five-Reel Video Slots

At one point these were the cutting edge in slot machine technology. They completely outclassed three-reel slots through their extra symbols, combinations and paylines. The payout schedule was also increased in these machines because people would put in more money to bet on more paylines. The larger screen also brought in more diverse and complex themes.

Progressive Slots

All casinos, both land-based and online have progressive slots in their repertoire nowadays. On this type of machine, a small percentage of every bet is diverted to the progressive jackpot pool. Each casino can set this percentage to however much they want and it can go up to a maximum of 15%. This jackpot keeps growing until someone wins it. On online casinos the network of slots can be all across multiple casinos.

You will usually have to max bet in order to qualify for the progressive jackpot. Because a part of every bet goes to this jackpot the overall winning combinations will pay less than they normally would. Some of these progressive jackpots can reach millions of dollars.

Stand-Alone Slots

These are the slots that are not connected to a progressive jackpot network. Usually they will have their payout schedule on the machine. This will be more than progressive slots because the machine is not diverting any amount of money to the progressive jackpot.

Multi-Payline Slots

All slots have “lines”. When a winning combination appears on a line it becomes a “payline”. Older machines usually took one coin and had one payline. Modern machines though can take more coins and have many more paylines.

Although conventional slots offer only straight lines for paylines, computer programmers learned how to program slots to also read diagonally and in a zig-zag. This means there are games out there with 50 or more paylines but a more common number is around 15 to 25.

Buy-a-Pay Slots

These machines will only pay out when you activate each winning combination with coins. For example let’s say a game has 3 winning combinations. If you want access to all three of them you will have to put in 3 coins, one for every combination. Even if combinations come up, if they haven’t been paid for you won’t be rewarded.

3D Slots

This is the latest in slot machine technology. They combine traditional slot games with a three-dimensional background and theme. This technology is pretty new so not a lot of casinos offer them but in time this will surely change.

I hope this has been useful in helping you choose which type of slot machines are best for your needs.
