Types of Slots

Whether you’re playing real money slots or playing for free, there is a wide variation of games that you’ll find.

You can choose by theme (the game might be based off a movie, a holiday, a band, etc.), but we recommend choosing by game type. There’s a wide variety here as well, but there are three types that are the most popular in US online casinos: 5-reel slots, 3-reel slots, and progressive jackpot slots.

3-Reel Slots

3-Reel Slots

The original slot machine layout

As the name suggests, 3-Reel Slots have 3 reels (columns). Players win big by getting three identical symbols lined up on those reels.

Given the recent popularity of 5-Reel Slots, 3-Reel Slots are now slightly less common at online casinos, but definitely still have their place, especially for purists.

If you like 3-Reel Slots, check out 108 Heroes Multiplier Fortunes, Reel ‘Em In 2 and Caddyshack.

5-Reel Slots

5-Reel Slots

By far the most common variant

These games – as you might expect – have 5 reels (or columns) that players can spin. 5-reel slots offer players hundreds of ways to win, literally.

5-reel slots generally come with multiple paylines (winning combinations), often more than 25. It’s with these slot games that you’ll typically see the most bonus features, like free spins, wild symbols, scatter symbols, etc. (more on bonus features later).

Progressive Jackpot Slots

Progressive Jackpot Slots

The slot type where you can win the big bucks

Another game type that’s appropriately named, progressive jackpot slots are games where the jackpot grows each time a player spins.

As each player – those playing for real money, at least – spins the reel, a small portion of his or her spin contributes to the overall jackpot. Given the popularity of progressive jackpot slots, these jackpots can grow quite large, and quite quickly.

The jackpots continue to grow until somebody wins, and then it starts all over again.

Big wins on progressive jackpot games have paid millions of dollars.

Video Slots

Video Slots

Think online slots couldn't get more interactive? Think again.

Most real money slots you’ll find, online and in land-based casinos are video slots (although there are definitely some old-school machines kicking around!)

Video slots are pretty self-explanatory — they feature a computerized, interactive, and themed versions of your favorite games.

Multi-Payline Slots

Multi-Payline Slots

Even more chances to win

Also known as MegaWays or Paytable slots, multi-payline slots are very similar to other slots, but offer more than one payline.

Depending on the game, paylines can be won in different directions, which means you could win with your matches that don’t appear in a straight line, like a diagonal match.

If you like multi-payline slots, check out Lucky Little Gods, Dream Date and The Phantom of the Opera.

Online Slot Features

As you may have noticed, there are a variety of in-game features that you will see in nearly every online slots game available. Each symbol changes the game in a different exciting way.

How to Play Slots

Slots are bright, flashy and fast – but that doesn’t mean they’re confusing. They’re just as simple as they are in physical casinos.

The goal is to spin the wheel until you find enough matching winning symbols on-screen.

There are differences per game variation, but your goal always remains the same: match winning symbols on screen to win jackpots.

Strategy & Tips for Playing Real Money Slots

Slots is a Game of Chance

There is no “winning strategy” – play for fun. Choose a game with a theme that interests you and just enjoy spinning the reels.

All slots are tipped in the casino’s favor, but not by the same amount. Our slot reviews all include the Payout Percentage – the higher, the better.

How Online Slots Work

With all the flashy graphics, numerous paylines and aesthetically pleasing sound effects, some new players may find slots overwhelming at first. We are here to assure you the games are not. When you break down how slots work on the web, it’s all very simple.

Bet Credit / Bet MAX Credit

Bet Credit / Bet MAX Credit

After learning how to play the specific slot game, you’ll first need to bet a credit. Every slot machine’s cost to play varies, but one credit typically earns you one spin of the reels. If you elect to bet MAX credits, you’ll unlock larger prize pools. In fact, betting MAX credits typically makes players eligible to win the progressive jackpots on specialty slot machines.

If playing real money slots, the credits you bet will be representative of money either from your deposit or any bonus you have picked up.

Reel Paylines

Reel Paylines

After you wager a credit, you need to pick your payline. Classic slot machine paylines simply go straight across, but modern online slots feature paylines that can win vertically, horizontally, diagonally and, thanks to scatter symbols, dozens of paylines exist. The more paylines you select to play, the more credits the online slot game will require.

Spin / Auto-Spin

Spin / Auto-Spin

With bets placed and paylines selected, it’s time to spin. Depending on the game you’re playing, an online slot can be spun once or multiple times with one click and the software’s Random Number Generator (RNG) algorithm will randomly come to a complete stop after a period of time. The RNG is licensed and regulated by third-party authorities for quality and safety so that it can be trusted by the casino operator and their players.  If you do decide to Auto-Spin, you’ll pre-pay for X-number of reel spins and be charged accordingly. For example, if you want to auto-spin 5x. You’ll be charged the bet credit multiplied by how many paylines you select multiplied by how many auto-spins you decide.

Collect Winnings

Collect Winnings

After the online slot reels come to a complete stop, the screen will let you know if you won or not. Most modern casino games offer some animation to highlight the fact that you won before adding credits to your casino account. If you lost, it’s time to spin again.



You’ve hit the big slot jackpot and are ready to cash out! Now what? Head on over to the casino’s cashier page and start to process your payout. Typical slot machine withdrawals take a few days, but can be expedited if you request your winnings in cryptocurrencies like Bitcoin.

Fairness in Real Money Slots

When looking to play slots with your own money, finding a safe casino site should be a top priority. Understandably, many players have questions regarding the fairness of slots given that they are a luck-based game. What you need to know is that good, reputable casino sites are heavily regulated.

Safe, secure casinos will show a selection of licenses in the footer of their website. All the sites recommended on Gamble Online are licensed and tested by independent, third-party auditors such as eCOGRA and the Malta Gambling Authority. These regulators have world-class reputations, in-depth auditing and strict rules which each casino must abide by in order to earn certification.

For online slots, one such rule is that operators must use Random Number Generators (sometimes referred to as RNGs) in the software to ensure that each spin is completely random. This randomness prevents the game from being rigged, though it does not prevent you from hitting a losing streak! With RNGs, the outcomes are random and past spins have no bearing on the result.

How to Choose Online Slots Games

Game variety matters. That’s why all of the casinos recommended on this site have a huge variety of slot games available. Choosing which slots to play can be overwhelming, so here are a few things you should factor in:

Free Online Slots

Many casino operators let you play their games for free in demo or practice mode. This is fantastic as you can browse the site, test the games and ultimately decide whether or not to play for real money there! We recommend playing free online slot games in demo mode first to see how often you win, how much you win and how you like the gameplay before risking any of your own money.
