To attract new customers, online casino offer many lucrative bonuses to new players like no deposit bonuses or welcome/ first deposit bonuses. Some casinos also offer a special type of bonus called free play casino bonus. The free play bonus is even more lucrative than the welcome bonus offered by online casinos. For instance, you may win up to $200 during an hour free play and if the minimum deposit at a casino is $20 then you will get 1,000% first deposit bonus. If you compare this with the common 100% welcome bonuses you may really like to take advantage of the free play casino bonus.
