The $50 no deposit bonus doesn’t cover all games; there are a few games that are unavailable for you to play. Quite a few casinos offer this bonus on specific games, such as slots, Keno and scratch cards. At such casinos, these are the only games you would be able to play with this bonus.
The excluded games clause applies to the fulfillment of wagering requirements as well. Because there are wagering requirements to be met, it is practical to play games that contribute towards its fulfillment. Slots, for example, contribute 100% and should therefore definitely be played.
Failure to meet this condition could result in your bonus winnings being cancelled or, worse, your account being suspended.
