The free play bonus is not like a traditional bonus. The free play bonus is a rather large bonus that you are given by an online casino that comes with a time limit. The player is given a time limit of something like an hour, and they can use that bonus on anything they want. However, there are times when the free play bonus is restricted to certain games. This might be an incentive to get people to play certain games, and it could be part of some sort of tournament that pays an even bigger bonus to the winner who can make the most money in the allotted time. The beauty of the free play bonus is that motivates people to play without having them stay on the site for too long. This might help someone who only has so much time to work with.
