A casino might offer the same bonus as another overall, but will require 1, 3 or several deposits to reach the full reward.

Get the Best Bonus Possible

Online casinos are always keen to impress new players, so you’ll often find casinos looking to entice you in with a sign-up bonus, or welcome bonus. Usually, this bonus is a percentage of your first deposit.

Your welcome bonus can be used to build your bankroll, allowing you to make more spins and gain more chances to win. It’s a good idea to read through the “wagering requirements” of any bonuses on offer prior to signing up, as casinos usually pay out these bonuses over a set period of time, which can vary depending on how much you wager.

Tip: Look out for casinos with big sign-up bonuses and low wagering requirements to maximize the amount of real money you have available to play with.

Slots Strategy

Online slots are entirely reliant on chance, but that doesn’t mean there aren’t things you can do to put yourself in a better position. Experienced players don’t leave it all down to luck. Instead, they follow a distinct strategy, like only playing games with the highest payout percentages, practicing their bonus rounds, and knowing their paylines inside and out. Here are a few strategy tips that might help you grab a jackpot next time you play slots online.

Quick Strategy Tips

Tip 1

Opt for games with smaller jackpots, over massive progressive prizes. You're far more likely to win this way.

Tip 2

Simpler slot games tend to have a higher payout percentage. Sometimes it's worth sticking with the classics, even if that brand new video slot looks exciting!

Tip 3

Only play online slots for real money at reputable, trustworthy online casinos. If you're ever in doubt, head to Casino.org to find top rated sites.

Tip 4

Keep your eyes peeled for enticing bonus rounds. This is where you'll find free spins and jackpots. And Knowing your paylines means knowing your chances of winning.

Meet the Games Makers

Frequently Asked Questions

How do online slots work?

The basic concept of spinning the reels to match up the symbols and win is the same with online slots as it is in land based casinos. The key difference playing slots online is that the variation of games will be wider, and you'll find that most online slots offer more reels and paylines, so your chances of netting a winning combination increases.

Can I play for free?

Yes. Every reputable online slots casino will offer players the option to play some games for free. This means you won't have to deposit any money to get started, you can simply enjoy the game for fun. But, you won't win any either. Despite that, playing free online slots is a great way to get a feel for casino slot games before you advance to wagering with real money.

What should I look for in an online slot casino?

After security and legitimacy (there are unfortunately a lot of rogue online casinos out there) you want to look at the payout percentage of an online slot. This is the percentage of the wagers paid in that the casino pays out in winnings. This is especially important if you're planning on playing for real money. A higher payout percentage generally means more money back in your pocket.

What’s a progressive jackpot?

This is a jackpot that builds up over time and then pays out a big sum of money to a single player. Most online slots casinos offer progressive jackpot slots so it's worth keeping an eye on the jackpot total and how frequently the game pays out.

Can I win real money playing online slots?

Yes you can. While online casino slots are ultimately a game of chance, many players do frequently win decent sums, and some lucky ones even score life-changing payouts. If you're in it for the big bucks, progressive jackpot slots will probably suit you best.

Are online slot casinos trustworthy?

Absolutely. Provided you play at a recommended online slots casino, and avoid any blacklisted sites, your personal details and your money will stay perfectly safe online. We independently test and verify every online casino we recommend so selecting one from our list is a good place to start.

How do welcome bonuses work?

Welcome bonuses reward players when they make their first real money deposit. The exact terms and requirements vary from casino to casino and some offers that seem too good to be true probably will be. Before you commit your cash, we recommend checking the wagering requirements of the online slots casino you're planning to play at. These will explain how much of your money you're required to deposit upfront, and what you can expect to receive in return. The best bonuses will offer large payouts on minimal deposits.

Which online slots pay real money?

There are a huge variety of online casino slots paying out real money prizes. These include classic three-reel slots, multi payline slots, progressive slots and video slots. Take a look at our list of top rated online slot casinos today to find the recommended games paying out real money right now.
