FAQ

How do I claim the 666 Casino Welcome Bonus?+
Create a new account at 666casino.com and choose to accept the Welcome Bonus at the end of the registration process. Make a minimum deposit of £10 and the bonus will be credited automatically. If it does not appear, contact support at support@666casino.com quoting your username.
Is the Welcome Bonus available to all players?+
The Welcome Bonus is only available to new customers who have not previously held an account at 666casino.com. It is limited to one bonus per person, household address, email address, telephone number, payment account, IP address, and device.
What are the wagering requirements for the Welcome Bonus?+
You must wager the bonus funds the number of times specified in the promotion before any winnings can be withdrawn. For example, on a 10x wagering requirement, if you received a £10 bonus you must wager £100 in total. Only wagers made from your Bonus Balance count towards meeting the requirement.
How do bets work when I have a bonus active?+
Each bet you place is made up of 50% real money funds and 50% bonus funds, provided you have sufficient amounts of each. You must also have enough real money in your balance to cover 50% of your casino stake in order to use bonus funds.
Which games contribute towards the wagering requirements?+
Different casino games contribute differently towards your wagering requirements. The specific contribution percentages for each game type are listed in the wagering contributions table on the 666casino.com website. Equal or low margin bets, such as betting on red or black in roulette or covering more than 25 of 37 numbers, do not contribute.
Are there any betting limits I must follow while a bonus is active?+
Yes. You must not place a single bet equal to or greater than £4, or £0.50 per line, or 15% of the bonus amount before wagering requirements are met. Breaching this limit may result in winnings being withheld or the bonus being removed from your account.
When does the Welcome Bonus expire?+
Bonus spins associated with a promotion must be used within 1 day of being credited, after which unused spins are removed. For specific bonus fund expiry periods, check the promotion terms applicable to your Welcome Bonus offer.
Is there a maximum withdrawal limit on bonus winnings?+
Winnings generated from bonus spins are capped at a maximum of £100. Any winnings from bonus spins that exceed this amount will be forfeited. Withdrawal of all bonus winnings is subject to the wagering requirements being fully met and the terms of the Bonus Policy.
