Few More ideas i have thought of,,, if you are a loyal customer like make a few deposits weekly you should get a bonus on at least one of your deposits and also add mystery prizes to machines for line hits or 5 of a kinds or anything that is rare to get get a cash bonus or prize delivered or every dollar you deposit you get 1 free spin up to a a 100 spins per customer or pick a customer from every 1 to 10 VIP Levels each month to set off on a week holiday or they can trade it in for bonus money if they don't want the prize or maybe pick a slot each week and whoever has the highest amount x on I think for the week at any bet size wins a cash bonus or prizes there so much more things I can think of but I'll leave it at that cheers from leovegas slot lover ???
