How to Find the Best Online Casino to Play Slot Games

Before you choose an online casino for real money play, there are a few factors to take into consideration. We’ll recommend the best online casinos for US slots players, but you want to do your own analysis based on your needs. Here’s a quick checklist to help you decide on the best slots site for you.

Safety

Sites need 128-bit SSL encryption to assure payouts are safe, a professional verification process, and the kind of payment methods which protect your identity.

Reputable Casino

It doesn’t matter if you win big if the casino operator doesn’t pay out your winnings — or pay them in a timely fashion. We recommend famous and reputable casinos.

Return-to-Player

A games RTP is important because this is the return you can expect. If two games are similar but one’s RTP is 97% instead of 93%, that’s important.

Game Selection

Most slots players get bored with the same games all the time, so you want an online casino with scores or even hundreds of online slots.

Favorite Game Type

5-reel video slots have a lot of bonus features, pay lines, and big jackpots. 3-reel classics have traditional themes and frequent hits of fixed jackpots.

Favorite Software Provider

Different slot game developers have different strengths. RealTime Gaming has lots of random jackpots and big progressive slots. Rival Gaming has lots of bonus features and interactive bonus games. Betsoft has fun themes and good graphics.

Best Online Casinos to Play Online Slot Games

When looking for places to play online slot games on the internet you are likely to find hundreds of sites promoting the best games. We encourage visitors to only play at recommended online casinos to avoid any scams.

How to Play Online Slot Games

Follow this step-by-step guide to playing online slots in a few easy steps. If you’ve ever played a slot machine in a brick-and-mortar casino, then the adjustment period will be short. Game developers design the online slot controls to mimic electronic slots in land-based casinos. In case you need a refresher, follow these four easy steps.

Playing Online Slot Games for Free

Can you play online slot games for free? Yes! If you haven’t figured out which slots game to play, most online casinos offer a free version of the game. On our slot game review, you will be able to play all the games for free. That way you can give the game a try before playing for real money.

Playing for slot games for free at your favorite online casino is simple. Just follow these easy steps:

• Step 1: Visit a recommended online casino.
• Step 2: Find the slot section
• Step 3: Search for your favorite slot game and click on the title,
• Step 4: You’ll be asked whether you want to play for real money or play in practice mode
• Step 5: Choose the practice play before actually paying to play.

Practice play is beneficial because you can learn the game controls and bet denominations before spending your hard-earned cash. Also, if the slot’s theme isn’t entertaining or annoys you, then you can find a better mobile slot to play.

Strategy to Play Online Slot Games

Las Vegas and Atlantic City casinos are experimenting with skill-based slots, but online slots do not require skill to play. Though slots games are games of chance, that doesn’t mean a player can’t benefit from a few helpful strategy tips. Follow these strategies when you begin to play slots online to save yourself some money. The more spins you play, the more chances you have to win a life-altering jackpot.

• Max Out Slots Bonuses: Most online casinos these days tailor welcome bonuses, reload bonuses, and weekly bonuses for slots. Read about casinos’ promotions and strategize how to max out your bonus cash.
• Read RTP Percentages: Play online slots with a higher return-to-player percentage. Simply by playing a game with a better-expected return, you save yourself money while you play.
• Calculate the Breakeven Point: Progressive jackpot slots have a point where the pot becomes so big that the game has a positive expectation. While this doesn’t increase the odds you’ll win, it does mean that you’re playing a slot with a good gamble.
• Use Money Management: Learn about basic money management techniques. Bankroll calculation, loss limits, and win goals won’t change the odds, but they will save you money during your gaming sessions.

Types of Online Slot Games

Online casinos have a wide variety of video slots available. Read through the list of slot games you might encounter as you get into the world of slots play online. Game designers sometimes mix and match concepts, so some of the online slot types below aren’t mutually exclusive.

• Classic/Fruit machines/3 Reel

  Called 3-reel-spinners, classic slots, or fruit machines, these were the original games with 3 reels and 1 pay line. Fruit slots were so-called because their reel symbols were fruit or other basic symbols.

• 5 Reel Slots

  The 5-reel slot machine came about when electronic slots were invented. These have more reels, more pay lines, and thus bigger jackpots.

• Video Slots

  Video slots use a video screen for more interesting graphics and themes. 5-reel video slots are the most popular slots because they use cutscenes, video clips, and interactive bonus games.

• 3D Slots

  The ultimate in video slots, 3D slots have 3D graphics that pop off the screen. 3D slots might portray movie scenes or have reel symbols that seem to come off the screen.

• Multiplier Slots

  Multipliers are popular because they increase the size of the jackpot by 2x or 100x their original value. Some multiplier jackpots have reached $100,000 or more.

• Licensed Slots

  A slot machine based on a pop culture franchise. You can play slots while being entertained by your favorite movie, tv, or comics characters — or musical acts.

• Multi-Line Slot Games

  Paylines are a way to increase the jackpot. Video slots often have 9 lines, 15 lines, 25 pay lines, or even 50 to 100 winning lines.

• Progressive Slot Games

  Instead of a fixed jackpot, the top prize increases over time. Every time a player spins and doesn’t win the jackpot, the accumulated pot grows.

• Wide-Area Progressive (WAP)

  The biggest progressive slots there are. Dozens of online slot games feed into the same jackpot, increasing it at a fast and exciting pace.

• Poker Machines

  This is the Australian name for slot machines. Many Australians call these the pokies.

• Virtual Reality Online Slot Games

  Online slots which require a VR headset. Virtual reality slots take graphics and bonus games to the next level with immersive videos.

• Mobile Slot Games

  Slots delivered to your smartphone or tablet computer screen with a downloadable mobile app. Slots played on Android phones, iPhones, and iPads for players on the go.

Understanding Slot Volatility and RTP

Slot players don’t need an advanced degree in mathematics to play, but it helps to learn the basics of probability as it applies to slots. Return-to-player (RTP) is important for determining which slot machine is best. The RTP is the expected payout expressed as a percentage. If a slot machine has an RTP of 97%, you can expect to win back $97 for every $100 wagered. If the RTP is 101%, then you can expect to win back $101 for every $100 wagered.

The higher the RTP, the better the slot machine. An RTP greater than 100% is a positive expectation slot, which almost never happens unless you play a progressive slot with a jackpot which has surpassed the breakeven point. An RTP less than 100% is a negative expectation slot. With a negative expectation slot, if you subtract the RTP from 100%, you get the house edge. For an online slot with an RTP of 97%, the house edge on the game would be 3%.

Volatility is another concept slot players need to understand. We talk about theoretical expected return, but in practice, each slots session is likely to deviate from the RTP somewhat. Volatility is how much a game tends to deviate from the RTP. As a general rule, slot games with high payouts but low return-to-player tend to have high volatility.

Slots with fixed jackpots tend to have a high RTP, which is why some players prefer 3-reel classics. These games are less volatile, meaning you’re more likely to have winning sessions and hit the jackpot more often. Playing slots with high volatility, you’ll have more losing sessions but tend to win bigger jackpots when you do win.

The important thing with volatility is it’s neither good nor bad. Some players want a game with high volatility because bigger jackpots are what they want. Some players prefer low volatility because they want more winning sessions and better odds. Learn what you want, study slots’ volatility, and you’ll pick slot games you like more often.
