Online Slots Guide for Players

Online slots are available for fun or real money at all top-rated online casino. To start playing, players have to create an account, verify the email address they provided while doing so, and login with their username and password. If the online casino requires a download, they may have to download the casino gaming software. If the online casino is an instant play one, they can start playing right on their browser.

Most players who just want to play the best online slots for free do not want to waste time registering an account and downloading casino gaming software at online casino. Such players can simply visit Best Casinos to play a few free slots for fun. A few top online casinos also allow players to play some of their games without registration or download.

Important Things to Know When Playing Slots Online

Here is a list of five important things that players should understand before attempting to play slots for real money:

Device Compatibility: All slots are not compatible with all devices. For example, some of the older slots are available only on the desktop versions of online casinos. Players will not find these titles in their mobile casino libraries. If players want to play a slot on desktop as well as mobile, they should first check if it is compatible with mobile devices.

Download vs. Instant Play: Some slots games are available only at download casinos, not at the instant play version. Players who use Mac computers or rely on public computers should choose slots that can be played right on the browser.

Payout Percentage: Before playing a slot, players should check out its payout percentage or return to player (RTP). This is the percentage of the bet amount that the online slot returns to players in the form of winnings. At most top rated online casinos, slots have an RTP of above 95%.

Classic Slots vs. Multiline Slots: Classic slots are excellent for beginners who tend to get overwhelmed with the rich features of multiline slots. These are three-reel slots with a single payline that have limited bonus features. Multiline slots, on the other hand, are ideal for seasoned slots players who crave the excitement of multiple bonus features, multi-level jackpots, free spins, multipliers, and other features.

Progressive Slots: Progressive slots are online slots associated with large progressive jackpots or jackpots that keep rising in value with every bet placed on the game till a lucky player wins them. Although the prospect of winning a million-dollar progressive jackpot is exciting, players should play progressive slots sparingly because they have a high house edge and are very difficult to win.

Picking the Right Slots Casino & Bonus

If you are a slots enthusiast, you will be disappointed if you select an online casino that does not focus on slots. Here are a few pointers for slots fans looking for the right slots casino:

Game Selection: Choose online casinos offering slots from multiple providers. Make sure that the portfolio includes progressive slots.

Free Spins: The best slots casinos offer free spins either as welcome bonuses or as part of promotional offers.

Bonus Offers: Players should understand that the biggest slots bonuses are not always the best ones. Before claiming a slots bonus, players should check out the bonus terms and conditions, especially the wagering requirements.

Why Should Anyone Try Playing Online Slots?

Here are a few advantages of playing online slots:

  • Higher payout percentages
  • Available for fun as well as real money
  • Play on desktop as well as mobile devices
  • Win large progressive jackpots
  • Claim attractive slots bonuses and free spin offers

Frequently Asked Questions (FAQ)
Which slots maker creates the best slot games?

All slots makers have their own style and distinct features, which makes it very difficult for experts to name the best slots maker. Providers such as NetEnt, Microgaming, Playtech, BetSoft Gaming, Rival Gaming, RTG, Aristocrat, and others have developed some great slots.

How much money can I win playing progressive slots?

If you are lucky, you can win jackpots worth millions of dollars as some progressive slots have multimillion-dollar jackpots. For example, Microgaming’s Mega Moolah has a jackpot that is worth at least $1 million.

Can you play all slot games for free too?

Yes, you can play all slots games free of charge, but you won’t win any real money prizes by doing so.

How do I know if the games are fair?

Top rated casinos have their random number generators (RNG) regularly tested by independent auditors. Players can view the testing certificate on the casino website.

What are bonus games?

Bonus games are side games that form parts of slots games. They can be activated by landing specific symbol combinations. They give players a chance to win prizes over and above the slot’s established payout structure.
