Another surprise sudden giveaway, too bad I was late to give an answer for it. Congrats to those 5 first users who answer it faster. I thought you would give something different, but it is the same as the previous bonus.
Instead of giving away no deposit bonus, why you do not try to make a competition where wagering is required? It would be much more fun IMO and all users will have the same chance to win (depends on the competition though).
