FAQ About Playing Online Slots

Does a slot machine offers a fair chance of winning?

Yes it does! All online slot machines are equipped with a RNG software. RNG stands for Random Number Generator, meaning, every time you play – spin the wheels – it is completely independent from previous rounds.


This is a good opportunity to dispel the myth that a slot machine that hasn’t ‘produced’ a good win in a while, is ‘ready’ for a win. This isn’t the case. Every round – every time you click the button – your odds of winning are on a clean slate as well as the amount of cash you might win.


What are the odds of winning on online slots?

You’ll be happy to know that the odds of winning on online slot machines is actually higher than playing one in ‘the real world’. Most online slots offer an RTP rate of more than 90%! RTP is Return to Player, meaning, any online slot machine will payback in winnings at least 90% of the money players bet on.


Important to understand – this isn’t per player. It’s not that every time you play you will win back 90% of the amount you bet, but rather that overall every machine ‘return’ in wins 90% at least of the money players gambled on it.


Is there anything that distinguishes UK online slots?

Basically, not really, except for maybe national pride. British or not, online slots are online slots. They run on the same rules, offer the same bonus options (depends on the game of course) and are lots of fun, whether you call them slot machines, video slots or anything else you fancy.


There’s a lot of talk about slot strategy. Any truth in that?

Well, if you’re thinking about a strategy in the traditional sense of the word, then the answer is no. Casino slots are a gamble game of luck. No way around it.


The only strategy you can apply is on how many pay lines to bet and what is your coin evaluation, meaning, what is the amount you bet on each pay line. The combination of these two decisions will determine the speed and risk of the game, and that’s pretty much it.


Do many slot casino sites in the UK offer no deposit bonus?

No deposit bonus, also known as a welcome bonus, is a casino site way of attracting new players to open an account. As other promotions, this isn’t a constant thing. It can change, depending on the casino’s needs and promotional calendar.


You can always specifically look for offers of no deposit bones though it is important to remember that even if you win, you wouldn’t be able to withdraw your winning cash unless you make a deposit.


This is how payouts normally work with online casinos – must make a deposit first. So no matter how lucky you are, let’s say you win millions in your initial no deposit game, you’ll still need to deposit your own money in order to enjoy your jackpot win.
