How to Win on Online Slots

So once you have signed up to a casino and found an online slot to try, the next question is of course how to win. It is important to remember that slot machines are games of pure luck and chance and that there are no tactics you can make use of. But by choosing some of the best-paying slots with a high RTP and/or jackpot, you can choose a game with the best payouts.

Once you’ve made a deposit in your casino, you can start playing for real money. A 5-pound deposit will get you far here! Open your slot, choose your bet and click spin. While all slot games are unique, the gameplay is normally very similar.

In order to win while playing, you will need to land a set amount of symbols on your paylines. Depending on the symbols you match (and how many there are of them) you will get a payout or bonus. You might for example get free spins, multipliers or access to a bonus game. If you win anything, you can choose to keep spinning from your balance or cash out your bankroll.

How Online Slots Work

Now that you know what an online slot is and how you can start playing it, it’s time for you to learn how it started and how it works today.

The first slot machine was built in 1894 and was a mechanical coin-operated game. It featured a 3-reel design with a few symbols and was very plain, with only one payline. They were popular in bars around the country and offered small prizes such as bubble gum or a few cents. Fruit symbols became common in modern video slots as a result of classic slot machines.

But, with the modernization and introduction of computers, physical and remote slots nowadays are controlled by software, and a random number generator is used by the slot machine’s program to decide which symbols will appear on the reels at the end of each turn.

As you would suspect, once slot machines became automated, players began to doubt how fair the game would be. However, online slots will have to pass numerous stringent tests to be considered fair. Typically, an online slot machine’s random number generator software is tested by an independent software testing organization. Then, the platform can be licensed if the results prove it to be fair and random.

Real Money Online Slots

If you want to win real money when playing online slots, you need to play real money slots. These are slots that you play from an online casino where you deposit and bet your money in the game.

In the game, you will be able to choose how much you want to bet (within the minimum and maximum betting limits). This normally ranges from less than £1 per spin up to £20 or more. Sometimes you can also choose how many paylines you want to be active, how many coins you want to bet per line, or similar.

When playing on real money slots, you will get to see your winnings as you spin. We always recommend going for slots with a high RTP (return to player percentage) of at least 96%. Progressive jackpot slots are of course the most lucrative ones, with potential winnings of millions of pounds.

Low Deposit Slots

With more and more low minimum deposit casinos on the market, you don’t have to spend much to play online slots. These days most online casinos accept deposits of £10 or less. This means that you can sign up at an online casino, deposit £10 and start playing right away.

While a £10 deposit might not sound like a lot, it will actually last for quite a few rounds on a slot game. Most slots allow you to freely choose your bet amount per spin, starting from just a few pence. With the minimum bet amount you can play up to 100 spins on some slots, and hopefully, you will get some free spins in there too!

Note that if you play with the minimum bet amount, you will also get the lowest winnings possible. For some jackpot slots, progressive jackpots are only paid out for players betting the maximum amount per spin.

Low Stake Slots

If you are looking to get the most spins out of a small deposit, you need to play a low-stake slot. We recommend the following slots, where you can set the stake as low as £0.09 per spin, giving you 111 spins for £10!

1. Starburst Slot from NetEnt

Starburst is a well-known video slot that can be found at most online casinos. This slot from NetEnt is often part of the welcome package when signing up at a new casino, giving free spins to new players.

We like to recommend this slot for two reasons: It is very easy to understand and enjoy, and it has a good range of betting options. At this slot, you can choose to bet only £0.10 per spin. This will make a £10 deposit last for 100 rounds!

With bonus features including an expanding wild symbol and respins, you can end up getting a lot of spins for just £10. Starburst is an easy slot that is perfect for beginners.

Mega Moolah Lion

2. Mega Moolah from Microgaming

Mega Moolah from Microgaming is another personal favourite. The online slot from 2006 is one of the most popular in the world. This is mainly thanks to its four millionaire-maker jackpots; Mini, Minor, Major and Mega.

At this slot, you can set the minimum coin value to £0.01. If you activate all 25 paylines (which you should in order to get a shot at the jackpots), you can then play with a minimum bet of £0.25 per round. This means that you can play 40 rounds with a £10 deposit and have your chance to win many millions in jackpots.

3. Dead or Alive from NetEnt

Another favourite from NetEnt, with a different theme than Starburst, is Dead or Alive. This Western-style slot is well-known for giving lots of free spins. And if that wasn’t enough, you can bet as little as £0.09 per spin!

The slot has 9 paylines and an RTP of 96.8%. You can collect free spins and multipliers, which will give even a coin value of £0.01 some nice winnings.

You can find Dead or Alive and other NetEnt slots at Online Casino London!

4. Turning Totems from Thunderkick

Both NetEnt and Microgaming have a lot of great slots to try out. But we also want to mention some other game providers. To start off, Thunderkick is one worth checking out. Their impressive collection of slots includes a lot of fun designs and themes, combined with simple gameplay.

Turning Totem is a colourful, Tiki-inspired slot. The set-up is unique with five totem poles instead of the regular slot wheels. Once you click Spin, the totems will turn and the symbols will change to unveil winnings combinations.

With a minimum bet of only £0.10 per spin, it is a fun game to try out for a few rounds. The game has some simple bonus features including a free spins mode.

Quick Online Slot Strategy Tips

1. Choose a game with a smaller jackpot

Although most people will go after the bigger jackpot bonus, choose the slot games with smaller jackpots over those with large progressive jackpots. While the allure of a big win is understandable, you’ll be far more likely to win this route.

2. Mind the paylines

Take the time to learn about the paylines in each game before you begin. You’ll know your odds of winning if you know how many paylines your chosen game has.

3. Always play on safe sites

Playing on safe sites ensures that your money will not be in vain, and it will not disappear because of intentional and unethical reasons. Just play real money online slots at reputable and trustworthy online casinos and you’ll be good to go. A good place to start is here at Kabono.

4. Make bonus rounds the holy rounds

Bonus rounds are very important if you want to nail jackpots and get free spins. You should know where they are and how to play them, so you can maximize your winnings.

Free Online Slots

You also have the option of playing at free online slots. This can be done in two main ways:

  1. Playing slots for free in demo mode with play money
  2. Playing slots for free using free spins or other casino bonuses

Tip!

If you want to test some online slots before spending your own money, playing for free in demo mode is a good place to start. Then you can test out the game and get used to the symbols and gameplay for free. But of course, if you play for free using play money you won’t be able to win real money.

Free Spins and other Casino Bonus Rewards

You can actually win real money while playing for free though; thanks to casino bonuses. Many casinos reward players with free spins that you can use to spin the reels for free while still winning real money. By adhering to the terms given (normally a minimum deposit, unless it is a no deposit bonus) the casino will give you a certain amount of free spins. Normally the free spins are given on a specific slot, such as Starburst or Book of Dead.

Some free slots UK players can enjoy are available at online slots websites – the game providers’ own websites or online casinos offering free games.

New Online Slots

It is not only new online casinos but also new casino games that are launched at a frequent pace.

While you would think that the hundreds of slots available at online casinos should be enough for most players, there is something about the fact that new is (almost) always better. So to keep up with current trends and to ensure the biggest wins, new online slots are developed and launched all the time.

Players too should watch out for new and emerging casino sites, because most of the time, they offer big bonuses and promos. But — you should always read reviews and think wisely when choosing your casino. New online slots normally come with improved graphics, big winnings and cool themes.

Some of the latest online slot favourites include the Megaways slots from Red Tiger Gaming and movie and TV franchise slots from NetEnt.
