One of the most common questions we have been asked by players is: are slots websites USA safe and are the slot games offered at casino sites fair?

Slots have a return to player that determines that amount the game pays back to players. This is usually around 96.5% but can vary a little.

Mobile casinos are hugely popular with UK players, allowing them to access their favourite slots games whenever they like, wherever they are.
All of the online casinos that we recommend can be accessed from a smartphone or tablet device; some have a native application you download while others are played via web browser.
The experience you receive is pretty much the same regardless of whether you play via app or browser and is near identical to the desktop version of the casino.
This means you can access the same number of slot games as well as the site’s bonuses and promotions, loyalty scheme and features such as tournaments and competitions on mobile.
The layout of the online slots site will automatically adjust to the device you are playing on, and most will allow you to switch between portrait and landscape mode.
The other great thing about playing games online via your mobile device is that all slots, not just the best UK online slots, do not use much data so can be played via 3G/4G as well as WiFi.
What bonuses can I expect when playing slots online?
Most people like to claim a bonus before playing the best USA slots online, and online casino brands are more than keen to welcome players with offers and incentives.
These are the types of bonus you can expect:
Deposit bonus – the operator will match your deposit up to a certain percentage. So if the match was 100% up to £100, you would have £200 to play with if you met the £100 deposit required.
No deposit bonus – the casino will give you a small amount of cash to play with without requiring you to deposit any of your own money.
Free spins – the site will give you a number of spins on a certain game that you play without using your own wagering balance.
Welcome offer – to welcome you to the casino, the operator will give you a bonus which usually includes a deposit match and free spins.
Reload bonus – if you have already signed up to a casino, from time to time the operator may match a deposit you make up to a set amount.
There are a few things to take into account when accepting an offer as most come with bonus terms. This can include things like minimum deposits, bonus wagering requirements and max win limits.
Other T&Cs include day expiry – how long you have to complete a wagering requirement – and restrictions on the deposit methods you can use to claim an offer.
We cover all of this in our reviews, but we also recommend you always read the terms and conditions of a bonus offer before accepting it.
