Slot game features

If you know what you like, searching by feature is another way to find the slots that suit you best. You will find that some sites will make your choice a bit easier by enabling you to browse by feature.

Many games will offer a combination of features, e.g. bonus rounds plus free spins, wilds and scatters, but do bear in mind that sometimes less is very definitely more as some games are so feature packed that you might find them excessively complex.

Here are some of the more common features that you might be looking for:

Return to Player

The RTP (Return to Player) for individual slot games is a figure, stated as a percentage, which represents the odds on the player winning on that game. You will often find the RTP published on the screen by the game and the more seasoned players will be looking for this. As a rule of thumb, you should only play slots offering 90% RTP or more.

You will find that online the RTP is higher than the bricks and mortar versions and that they can go as high as 98% or 99%. In theory, a higher RTP indicates a lower chance of losing significantly over time.

How does it work? Here’s an example:

If you play a slot that displays a 97% RTP, this simply means that for every £100 you play the slot game should pay out £97 over time.

Remember that they cannot guarantee the stated RTPs for every session. They are a long-term expected figure, and the actual payout percentage for you as an individual playing in one session may well differ significantly.

When selecting an online slot game to play, you should be aware of a factor known as ‘variance’. It relates to the fact that games with slightly lower RTP may offer more opportunities for bigger one-off payouts. High variance games tend to pay out more, but do so less often, and low variance games payout lesser sums, but more regularly.

Online Casinos and software providers

Where to start? Look for the casinos that offer continuous bonuses and promotions, but also those that provide good customer service, like 24/7 support and a 24-hour cash out rule. They should also have the UK Gambling Commission seal of approval so that you can be assured of their commitment to fair play. This information should be readily available on their websites often somewhere at the foot of the page.

You will find that many online casinos offer games from a range of casino software providers. It ensures that the players get a more varied choice and will keep them from straying off to other sites. So, if you are a relative newcomer to the world of online slots go for a casino that offers games powered by ‘varied software’ for the widest range of gaming experience.

You’ll soon find something that you like, but be sure to take advantage of the free slots when starting out. That way you can get a feel for the casinos and software features that spark your interest.

Some regular players, who after experience know what they like, tend to stick with a small handful of favourite sites while others base their choice on who made the software.

Who are the best online slot makers? Three big names are consistently at the cutting-edge of slot technology, and they are constantly adding new games to their offering.

These are Microgaming, Playtech and NetEnt.
