Special Features of Online Slots and Basic Gameplay
Few people know that slots are based on principles of poker. Yes, bar staple poker became the online game we all know and love. Clearly, it’s undergone some changes. Physical cards changed to actual reels and card suits changing to fruit symbols, and then on to other more exciting variations.
Similarly, online slots provide fully automated reels at the touch of a button, ease of play at home with better graphics, and modern themes. As the game has modernised, the rules have developed. There may be more bells and whistles but you can learn to play slots with relative ease. Players decided how much to bet by choosing how many coins to play per payline and how much each coin is worth. Once you’ve chosen the wager your job is done, but there are a few things to bear in mind when selecting a slot.
Early slots were pretty simple – with one solitary payline. One of the biggest differences in modern versions is the huge number of paylines available in the game. Top slot casinos have games with anything from 1 to well over 1 thousand to play. Payouts can be earned when you land a winning combo on any that are activated.
The main thing to understand is that you will only win payouts on activated paylines (the lines you have bet on). Think about it: if you bet on just 5 out of 20 lines, and a winning combo falls on a line you didn’t bet on (deactivated), you get nothing. In this sense, you’ve got to be in it to win it. Winning lines can be simple and straight, or run in all directions, horizontal, vertical or diagonal across the reels. Most slots feature adjustable paylines – expect fixed payline slots which require you to bet on all to play.
There are some fantastic features out there which only add to the excitement of spinning the reels, tumbling reels, for example, allow winning spins that never seem to end as winning combinations evaporate and more symbols fall into their place. Free spins and exciting bonus rounds are awarded in game, and these can be unlocked or awarded at random. Last but not least are jackpot games. These games include a rising progressive jackpot where lucky players can win in multi-million-pound jackpots!
Being Smart on the Reels
The nature of slots is that they’re completely random. Casinos use random number generators for fairness so you can’t predict upcoming winning combos, and there’s not a lot to suggest by way of tactics. Still, there’s more to slots than finding a slot machine, hitting spin and waiting to see what happens. We’ve set out some tips to using online slot features to your advantage.
Slots is a low skill game of chance but still ways to make the best of your game once you’ve got the rules down. We also recommend that if you play progressive slots, make sure you bet high enough to be eligible for the jackpots, it would be a shame to miss out because you’ve missed this one tiny detail.

Special Features of Land-Based Slots
Admittedly, land-based slots are pretty cool. These retro machines with their vintage sound effects are relics from another time. Nudge buttons let you physically control the reels moving or pulling one armed banded ‘arm’ sets them off. The most exciting thing about the classic machines is when you win physical coins in real time.
There are striking disadvantages to playing physical slots over their online counterparts. For one the jackpots available are considerably lower. Another significant deterrent is the RTPs. Physical slot machines have far lower RTPs than those offered by an online casino.
How to Find a Top Slot Casino?
A decent land-based slot casino will offer a limited selection of great slots. With regards to online slots casino in the UK, there’s more room for you to be selective as there’s so much more on offer! Thus, keep in mind that the criteria of our main reviews page for casinos in general still applies here, but there’s more for slots players to considers and more than just games variety to look out for.
Keep an eye out for a casino with online slot games from many providers – your site of choice should be versatile and have established partnerships with developers. You’ll want a good spread of the big names for the best choice themes, design styles, functionalities, and special features.
All major casinos offer web apps or native apps, so you shouldn’t have much trouble finding your favourite slot to play on a mobile device. Software providers cater increasingly to their mobile-based clientele, with games being formatted and optimised for handheld devices from their inception.
Look out for casinos with favourable conditions for slots players. Most major casinos offer a 100% wagering contribution for online reels – but always check the small print to be sure! It’s also wise to choose casino with regular slots bonuses and promotions if you’re a returning player.
Top slots casinos offer large selections of slots including plenty of jackpot slots. We expect to see a world class software developer as well as attractive bonuses for slots players. Finally, given the age of mobile first, well-developed slot mobile solutions are a must.
