When you go to a place that has gamblers bonus you sign up and you have a sign in name and a password so when ever you go to one of these establishments you just sign in. They have a poker bonus that has all the cards from 2 to A and the bonus starts off at some high amount like 15,000 for quarters. As you play that amount goes down and when you fill your card, meaning you get a four of a kind of each number then that bonus pays. The closer you are to finishing the faster the bonus drops.
Hope this helps
