Slot machines are usually the most profitable part of the casino floor. More space is dedicated to slot machine gaming than any other category of casino game, from Las Vegas to tribal casinos to Monte Carlo. Though the world of slot machines is vast, it doesn’t take long to figure out how they work and how to play them.

Types of Slot Machines

There are a few different categories of slot machines, though a modern slot player only really needs to understand straight slots, video slots, progressive slots, and Buy a Pay slot machines.

Straight slots – These are traditional slot machine games. They don’t provide bonuses, and they pay out according to a standard pay table. Straight slots are the easiest slot machines to play. They’re excellent for beginners. If you’re just becoming familiar with the basics of slot gambling, stick with the straight slots. If you get bored or you want more action, consider moving on to video slots.

Video slots – “Video slots” are the fancier slot machines on the floor. These machines usually have larger screens to display movie-quality video and animation. These slots tend to be loud, flashy, and are usually placed in a conspicuous part of the casino floor to attract attention. Video slots tend to have licensed themes, like from movies or TV shows, and some of them are just loaded with bonus games and other features.

Progressive slots – “Progressive slots” are linked to other machines in the casino or even other slot machines at casinos around the country. The top jackpot for these machines is linked to other slots. A tiny percentage of every bet is added to a progressive jackpot total. Spin the right combination on your machine and the entire progressive jackpot is yours. Progressive slot machines tend to offer a worse payout percentage than machines that aren’t linked progressively, so it’s a bit of a risk to switch to a progressive machine and chase the jackpot.

Buy a Pay slots – Buy a Pay slots games have more than just one payout table that you can wager on, and you choose how many tables to bet per pull. Betting an extra payout table costs an extra wager for each one. Yes, it ends up costing more money to bet on Buy a Pay slots, but your chances of winning are better, too. Because different combinations pay out different amounts on each activated payout table, the number of potentially lucrative combinations goes up.


How Do Slot Machines Work?

Gone are the old electro-mechanical slot machines with static displays and heavy frames. These days, everything inside of a modern slot machine is controlled by a random number generator, a fancy device that spits out numbers all day. For example, when you pull the lever or push the spin button or in any way trigger the reels to start spinning, that random number generator comes up with a random number to assign to your spin, and that is how it is determined if you win or lose.

If you understand that today’s slot machines have a brain that runs on random numbers, you can avoid falling for inaccurate slot machine strategy advice. Anything you read online or hear from a friend that suggests that slot machines can be beaten is bunk. Each spin of the reels of a slot machine is unique from the one before it and has nothing to do with the one after it.

Tips for Playing Slot Machines

So now that you know slot machine outcomes are based on a random chance, do you feel like there’s no way to beat them? Don’t feel that way. Lots of people win lots of money playing the slot machines at their nearby casino or online gaming site. The trick is to keep your gaming within responsible limits and have fun.
