🤑 Best Casino Site for Real Money Online Slots
Finding the best online casino site for your favorite online slot games is going to involve a lot of personal preference. If you’re looking for the biggest selection of online slot games and a history of paying out the biggest jackpots, BetMGM Casino should be where you start.
BetMGM offers nearly 5,000 online slot games to choose from, and more than 500 progressive jackpot slots.
You’ll find all the classic games like Buffalo, Bison Fury, Divine Fortune, Loot ‘En Khamun, and 88 Fortunes, but BetMGM separates itself with the massive amount of exclusive slot games that it offers.
MGM Grand Millions—and its high roller and megaways off-shoots—Majestic Lions, MGM Riches, and many others are among the most played online slot games in the US and also feature some of the biggest jackpots.
You are sure to find great online slot games at Caesars Palace, DraftKings, FanDuel, Hollywood Casino, and other online casinos available in your state, but they’re all still chasing BetMGM.
💰 Online Casino with Biggest Real Money Slot Payouts
BetMGM is also the best online casino for real money payouts from online slot games.
Payouts at BetMGM have gone over $1 million on several occasions, and you will consistently see live progressive jackpots with cash prizes listed in the hundreds of thousands. This is mostly because of the large amount of players at BetMGM, and the exclusive titles that it offers.
Winning large jackpots is not at all exclusive to BetMGM, however. All online casinos that offer progressive jackpots—which is all of them —provide a chance of winning a huge prize. It just tends to happen at BetMGM more often.
That being said, DraftKings Casino, and Borgata Online Casino have also had multiple $1 million-plus jackpots in recent years.
📋 Types of Online Slot Games
There are several thousand real-money online slot games available at legal online casino apps. So many that it can actually be a bit overwhelming.
Do you want jackpots? Three-reel slots? Five reels? Video slots? Whacky-themed slots? We could keep going, but the reality is there are almost too many to choose from.
Fortunately for you, casinos do a good job of separating them into categories to help you find what you need. Here’s a breakdown of some of the bigger categories.
Classic Slots
Casino slot machines have come a long way from the early Vegas days of cherries and 7s spinning on a three-reel machine in a back room. But if you prefer that, online slots have you covered.
Often filed under “stepper slots” on casino apps, these three-reel classics can provide a bit of nostalgia while still paying you real money on your iPhone. Some examples include:
- Triple Treasure
- Triple Diamond
- Wild Wild 7s
- Blazin’ Gems
- Cash Machine
Video Slots
Video slots were the next step in the growth of slot machines, as they were able to go from the three-reel mechanism to more reels and moving images on a screen. This started in retail casinos, and easily made its way to online platforms.
Technically, all online slots are video slots in a way, as they are all animated and running on random number generators. But if you’re looking for flashy animations and icons, a video slot is what you want. This grouping is also where you’ll find many of your themed slots.
Video slots also allowed slot games to create more bonus features and bonus rounds that could entice customers with the chance at bigger payouts.
Here are some examples of video slots:
- Guns ‘N Roses
- Mega Jokers
- Blood Sucker
- Cleopatra
- Wheel of Fortune
Multi-Payline Slots
With the advent of video slots came the ability to offer multiple paylines beyond straight across or diagonal.
Multi-payline slots offer you the chance to win with icons in several different lines and combinations. The incredibly popular megaways slots fall under this category, among others.
They often feature reels that change sizes to allow for more connections. Fair warning, for a beginner slot player, these games can be a bit confusing to follow. To help understand, view the information section of the game and check the paytable to see which paylines can earn you money.
Here are some examples of multi-payline games:
- Divine Drop
- Big Catch Bass Fishing
- Divine Fortune
- Buffalo
- Cash Eruption
Progressive Jackpot Slots
Progressive jackpot slots aren’t necessarily their own category, in that all of the above are included in some way. But online casinos will separate them to make it easier for you to find.
Whether you’re playing a megaways slot or a three-reel slot, part of your wager will go toward a progressive jackpot which builds up until it’s won. These are the big wins you see casinos advertise to help bring people in.
✅ Advantages to Playing Online Slots
The No. 1 advantage to playing online slots is convenience. The fact that you don’t lose much—if anything at all—in regard to the overall social experience of playing a slot machine at a retail casino is just a bonus.
Online slot machines work much like in-person casino slots, but you don’t need to drive to the casino to play and win big. Simply pull out your Apple or Android device, open the online casino app of your choice, and start playing.
Your bankroll is automatically connected to the game, and your winnings will automatically be added to it as you go. There’s no need to cash out when you’re ready to leave or print out a ticket before moving onto the next slot game of your choice. Just exit that game and pick the next one.
💬 Understanding RTP for Slot Games
When playing casino games, you can never guarantee a win. But you can look at a game’s return to player ratio, or RTP, to find out which games payout most often.
RTPs on slot games typically come in at 90% or higher, with many coming in at 95% or higher. Some even claim to have a 99% RTP, with Mega Joker being the example most often cited as the highest RTP slot.
Those numbers sound incredible for players. A 90% chance to win? How can online casinos even make money with a high RTP like that?
Well, all that RTP number means is that for every $100 bet on the game, $90 typically is returned to players. It doesn’t mean you’re going to win nine out of 10 spins.
Yes, looking for a high RTP is a good way to find online slots that pay the most often. But understanding what the number actually means is even more important.
Volatility Ratings for Slots
Another number you will see when looking up the RTP for slots is the volatility rating. A high volatility rating suggests that slot pays out less frequently, but at higher amounts.
A low to medium volatility rating suggests it pays out more often, but at lower amounts.
So, if you’re looking to win more often, lower volatility slots are your target. Here are some examples of low volatility slots:
- Da Vinci Diamonds
- Starmania
- Fortune Coin
- Starburst
- Reel King
If you’re chasing bigger jackpots and OK with seeing more spins result in losses, here are some high volatility slots to look into:
- Jack In A Pot
- 88 Fortunes
- Zodiac Infinity Reels
- Fruit Shop Megaways
- Towers of Olympus
🆓 How to Use Free Spins for Slots at Online Casinos
As a customer at an online gambling site, there will be multiple occasions when you are awarded free spins to be used on slot games.
Whether those come as a welcome bonus, a current customer promotion, or the online casino deciding to promote a new slot game, those free spins are often connected to a specific game or set of games. Sometimes, they might be connected to games from a specific studio, such as NetEnt, White Hat, Red Tiger, or others.
In order to use those spins, you will want to view the bonus section of your account and opt-in. Then go to the game listed in your bonus, where you will be alerted that you have free spins available, and it will ask if you’d like to use them.
Nearly all online casinos and slot games will feature a free spin counter as you’re using them, so you can keep track of your free play prior to using your own real money.
Winnings from this slot bonus might be subject to playthrough requirements, meaning you will have to wager it so many times before it becomes a withdrawable balance. Make sure to check the terms and conditions (T&Cs) of any bonus you accept.
Bonus Spins
Another form of free spins are bonus spins that you can earn while playing the game. These are often triggered when you get a certain amount of icons on a payline which will send you to a bonus game or bonus round.
The game will typically make these re-spins for you, as they are not costing you any money. The winnings from a bonus round will go directly into your bankroll, and this is usually where most of the largest jackpots are won.
Bonus games in an online slot also feature some of the more exciting animations, such as scatter symbols, and a different look from typical gameplay.
