666 Casino offers an exciting welcome bonus that no player will be able to look away from. The welcome bonus is also themed to go with the casino’s devil concept, making it more exciting. The welcome package offers a match bonus of up to £66 on your first 6 deposits.

On the first deposit, players win a 100% match bonus up to £66. They also win 66 free spins to play on the Book of Dead slot. The second deposit offers a match bonus of 50% up to £66 but no free spins from here on.

The third, fourth, fifth, and sixth deposits also offer the same as the second deposit, which means a 50% match bonus of £66. Once you make the minimum deposit, which is £20 for the first time, you get to open the welcome package.

The maximum bonus bet you can make when playing with your bonus funds is £5 on each game. If you place a bet higher than this, the casino can take away your bonuses. With the cash prize, you can play different online slots. The cash bonuses offered by 666 Casino lasts for 30 days, after which any unused bonus will be taken away.

To turn your total bonus funds to cash funds, you have to fulfil the wagering requirements—this 35x the value of your cash deposit plus the bonus funds. For example, with the first deposit of £20, you get a reward of £20. Thus, your wagering requirement is 35 x £40. Bonus funds cannot be withdrawn until this is fulfilled.

Slot games, except those specified by the casino, contribute to 100% of the wagering requirement. Other games don’t contribute to the wagering requirement except for scratch cards and keno.
