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 to win. Experienced players follow a distinct strategy, like only playing games with the highest payout percentages, practicing their bonus rounds, and knowing their paylines inside and out. Follow these guides to give yourself the best possible chance to win jackpots on slot machines online.
As a slots player, the payout percentage tells you how much of your money bet will be paid out in winnings. This means you can work out how much you could win on average. For example, if a slot game payout percentage is 98.20%, the casino will on average pay out £98.2 for every £100 wagered. This is also known as Return To Player (RTP). We outline the RTP for each casino we rate so you can find the payout percentage on a slot machine easily.

Quick online slots strategy tips
Go for smaller jackpots
Opt for real money slots games with smaller jackpots, over massive progressive prizes. The allure of a big win is understandable but you're far more likely to be a winner this way.

Stick to safe sites
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.
Look out for bonus rounds
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.

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 with 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 slots for free?
Yes. Every reputable online slots casino will offer players the option to play free slot games. 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 sites on our list of those to avoid, 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 payout the most?
Progressive slots games pay out the most money, with Mega Moolah being the record breaker at €18,910,668.01. Our list of top rated online slot casinos show you the recommended games paying out real money. There are a huge variety of online casino slots paying out varying sums. These include classic three-reel slots, multi payline slots, progressive slots and video slots.
How do I pick a winning slot machine?
To try improving your chances of winning a jackpot, choose a progressive slot game with a fairly small jackpot. These games pay out most often. Another method is to pick simpler games. If a game is complex and exciting, software developers have spent more time and money to build it. This could mean frequent wins are less likely. Either way, the slot machine will still be fair and random.
Are online slots rigged?
No, all regulated online slot machines are completely fair. The results are random every time, meaning that nothing in the game is rigged. To ensure fair play, only choose slots from approved online casinos, such as those we list above. Playing at any of these will give you a fair chance of winning.
How do I pick a good slot machine?
You need to make sure you are playing slots with high Return to Player (RTP) percentages, advantageous bonuses, good overall ratings and a theme you appreciate. Check out our recommended slots to play in 2023 section to make the right choice for you.
What is the best online slot site?
The one that offers the biggest payouts, jackpots and bonuses along with exciting slot themes and a great player experience. To find out our top casino for this month head to our toplist.
What is the legal gambling age in the US?
