Types of Slots

Whether you’re playing for real money 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.

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 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 slot game available online. 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 Slots

How Online Slots Work

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

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.

Playing Slots on Mobile

Whether you’re waiting for a train, early for an appointment or relaxing at home, you can play slots on your mobile phone and win real money! Many online casinos have mobile apps which make playing slots seamless, though their games can often also be played on an internet browser. The vast majority of casinos allow registration and deposits through mobile, so as long as you have a data plan or wifi, you could be playing in minutes.

Playing mobile slots is incredibly similar to playing on a desktop, and indeed some of the games and jackpots are exactly the same. If you need help choosing a mobile casino, check out our expert reviews.
