In assessing this casino's safety, our review team has considered crucial factors such as the fairness of its Terms and Conditions, licenses, player complaints, customer support, limits, and other relevant aspects to determine where it falls on the spectrum from safe and legit casino to a potential scam.
Our evaluation has led to the casino's Safety Index, a numerical and verbal representation of our findings regarding safety and fairness of online casinos. The higher the Safety Index, the greater the assurance of playing and receiving winnings without problems. A Very high Safety Index of 9.3 puts 666 Casino at the top of our ratings. It scores near the top for fairness and safety. Read our 666 Casino review to discover more about this casino and decide whether it is a suitable option for you.
Safety Index – 666 Casino fairness and safety
In determining a casino's Safety Index, we follow complex methodology that takes into account the variables we have gathered and evaluated in our review. This includes the casino's T&Cs, player complaints, estimated revenues, blacklists, and various other factors.
In our review of 666 Casino, we thoroughly read and reviewed the Terms and Conditions of 666 Casino. We came across some rules or clauses that we did not appreciate, and all in all, we find the T&Cs to be somewhat unfair. Unfair or predatory rules have the potential to be held against players to defend withholding their winnings. Therefore, based on our findings, we advise caution if you choose to play at this casino.
Based upon our estimates and collected information, we consider 666 Casino a very big online casino. This casino has a very low value of denied payouts in player complaints with respect to its size (or it hasn't had any complaints). When evaluating a casino, we consider the number of complaints in relation to the casino's size, since bigger casinos generally receive a higher number of complaints due to a larger player base.
Based on our findings, no important casino blacklists feature 666 Casino. The presence of a casino on various blacklists, including our own Casino Guru blacklist, is a potential sign of wrongdoing towards customers. Players are encouraged to consider this information when deciding where to play.
In our comprehensive review of all relevant aspects, 666 Casino has attained a Very high Safety Index of 9.3. For players seeking an online casino that prioritizes fairness in the online gambling experience they offer, this casino is a fantastic choice.
Note: 666 Casino is linked to 52 other online casinos, based on the information we've collected. Because of the relationship between these casinos, we have considered the qualities of the related casinos when calculating the Safety Index of 666 Casino. They had a positive effect.

We found some questionable rules or clauses during our review, because of which we consider the Terms and Conditions of 666 Casino to be somewhat unfair.
Note: Our particular discoveries from the T&Cs analysis are available here.

Safety and fairness
Safety and fairness
Take a look at the explanation of factors that we consider when calculating the Safety Index rating of 666 Casino. The Safety Index is the main metric we use to describe the trustworthiness, fairness, and quality of all online casinos in our database.
We go over the terms and conditions of each casino and look for unfair rules that could potentially be used against players. Any clauses we consider to be unfair result in a lower Safety Index for the casino.
Casino size
Big casinoVery big group
Bigger casinos are generally safer for players, because their high revenues allow them to pay out even very big wins without any issues and their quality has been proven by a large number of players. We take into account estimated revenues over the last 4 years and also consider revenues of related casinos.
Player complaints signify that the casino does not treat players right or deal with certain situations correctly. We consider the number and seriousness of complaints in relation to the casino’s size, as it can be expected that sites with more players will also have more complaints.
Blacklists
None
0x
If a casino appears on relevant blacklists, it is usually a sign that it has some negative qualities. We consider each blacklist and decrease the casino’s Safety Index based on our view of the situation and its seriousness.
Other factors
Neutral
There can also be other characteristics and qualities of a casino that influence its Safety Index, such as win limits, low withdrawal limits, fake games or licenses, bad or no customer support, a network of land-based shops, etc.

this is a casino i would recommend if you are starting out in the casino world for the 1st time, very user friendly, nice selection of casino games, however if you are looking for a full on casino experienced users should probably look elsewhere, there is a lot of top slot providers missing, for me in ireland pragmatic play, no limit, bgaming, relax gaming, push gaming, backseat gaming and bullshark gaming are all missing/unavailable to me which left me with only a handfull of slot provisders i like, having said that the slots are up to date and a lot of new slots are here, the site is very buggy, constantly refreshing or you get a pop up something went wrong, this became quite annoying after a while, i also decided to play blackjack, i am a low stakes player and could only find 1 table for 5 euro, none for 10 euro and 1 for 15 euro, this is not a great selection for the low stake gambler, i did manage to get on the 5 euro table a few times after waiting though and it was smooth, another thing experienced slot providers will notice instantly is no slot filter, when you finish playing a game you you have to x out of it then retype the provider into the search bar to go back to that provider, this is also very annoying after a while Huge plus side to this casino though is the lightning speed of verification and withdraw times, i did both on a SUNDAY! sent in documents and withdrew money and both were nearly instant, this is exellent news for all players as we all now a lot of casinos dont deal with payments at the weekend
all in all i had a good time here errors and smaller selection of slots than i would like but i will go back again for the hassle free deposit and withdraws
deposit and withdraw by paypal
very fast verification even on a sunday!
money withdrew no hassle and in paypal account in minutes!
friendly customer support
lot of slot providers missing
buggy site, kept refreshing/crashing a lot and everytime i log in i get a pop up saying verify your email even though i had already!
withdraw fees
lot of ooops something went wrong trying to play a lot of hacksaw games
Any ones who planing to play on this side don't waste your money and time it's totally scammed.I deposit from my revolut account.And when I win,and try to withdraw my money 3/4 days my withdrawal was on pending and after so many time contract them they asked me my bank statement and id.I provided them Then they said wait for 48 hours and after 3 days said we didn't not expect Revolut bank account.I told them my deposit was also from my revolut about and they give a silly answer we except only deposit from revolut but you can't withdrawal to you revolut account.Now they took my deposit and withdrawal both...This site is totally scam...
Very poor customer service
Wait of time
When you deposit they expect Revolut but when you try to withdraw you win they didn't expect Revolut account. Very silly
