£100 and £25 bonus from first deposit...all dead spins-same as all the other sites! Not a penny back!! Absolute joke!....
All these sites are rigged for you to lose a fortune nowadays, its all changed in the last 1/2 years! Time to give up gambling now I think...it's as if they are purposely leading people into gambling addictions because you are forever trying to make up the money you've lost but you wont because its fixed for you to lose again & again & again....

Edit: In response to the automated regurgitated transparent drivel that was sent as a reply to my review..WHAT A LOAD OF B*******!!!

On of the worst site ever

On of the worst site ever I played on. I payed over £5000 on big bass splash with no return. Ive been spinning on £1 after depositing £700 i had 3 scatter from there my return was £17.10 and its alway like that amount of return. This sit has fixed the game so no one wins. People avoid this site and dont lose your money like i did. Best site to play is 32red.com or pokerstarscasino.uk
They charge you to deposit also charge you to withdraw. I'm not going to say anything more but people 100% avoid this site. This site is a con and fraud. Anything to do with PLAYFRANK avoid it.

(1) They charge you £ for deposits & withdrawals

(2) the sign up bonus says its a 35x wager which is fine but when I checked my account it said I need to wager £700 which they don't make easy for you to opt out of it
.
(3) I also didn't receive my free spins for my sign up even after making multiple deposits of the required amount. £20+ 3times

(4) Other than all of that the slots and providers themselves are good not sure on the pay-out I made my money back and left as the site is stressful with all the issues I ran into, I will not be returning

(5) Site seems to refresh on its own when searching through it which can get annoying

(6) When going from slot to slot I ran into a issue that said I could not have multiple games open at once which I didn't so I had to close and reopen the site multiple times before it fixed itself

(7) When depositing the website errors and you have to refresh the site for it to work. proper buggy

Overall of my 2hr experience the sites incredibly buggy which makes it stressful & CHARGING ADDITIONAL fees to deposit and withdraw is NOT ok
there are better casinos to use..

AVOID AVOID RIP OFF DEAD SPIN AFTER DEAD SPIN

If you enjoy playing games with nothing but dead spins never getting a bonus then this is the site for you, this site offers no rewards of free spins etc like other sites their games are continuous dead spin after dead spin if u are lucky to get a win don't hope for anything more then 8p I've deposited on a few occasions as I wanted to give it benefit of doubt after 6 time of depositing and yet again losing my money and getting games with nothing but dead spins and never winning anything no bonus on any game i spoke with customer service online chat who just offered to close my account there is no value to customers this is another greedy site that is only out to line their own pockets. If anyone takes anything from this please please keep your money treat yourself and family to a hoilday or a day out you will value that alot more then losing your money to this site.

Rubbish, never see a bonus

Rubbish! Never get a bonus and the small wins are always just that- small! Don't think I've seen one over £5! I only play low stakes but the games I tend to play always play better on other sites and 9/10 bonus atleast once! AVOID!!

One to avoid

Avoid. Poor gaming and you pay a deposit fee for the pleasure. One to avoid at all costs.
No live chat option, because they know they would be inundated with complaints.

Approach with caution

I have to red flag any suspicious activity when it comes to gaming. Luckily I only play low stakes so don’t lose a fortune (always set deposit limits folks!!). When you play low stake you get a sense when something isn’t right. £60 no bonuses on 10p play should worry anyone. You aren’t guaranteed to win in any game of gambling but the odds of the above are very slim without some form of worrying practice.
If you want to take a punt (I mean it could be severely odd occurrence in a random scenario, but unlikely) also be aware that they will charge you a fee for depositing. Another thing that’s very unusual.

I wanted log back into my account and it denied me access. At this point I just want to withdraw my money and not use this site to bet anymore. Very disappointed. I even changed my password and still nothing.
