Crown Bingo is another site that I have not really heard of but I have to admit that I am hooked and this is a great time to take advantage of all the great benefits and promotions that they have to offer this month. If you join up you will receive the very common bonus that allows you to double up the first amount that you have deposited and this is where the comparison with other sites end and with that I mean that instead of the usual one hundred pound double up maximum it has been slightly raised to a whooping two hundred and fifty pound so potentially you could have a starting balance of five hundred pounds which should be enough to keep you on the bingo trail for a while to come.
