im confused on something -
If you are wanting to try a free chip and it has a max cash out lets say 100 for 100 $ Chip - Why bother ? if you get past 100$ on it you cant ever cash it out ? i am lost sorry but someone please tell me the theory behind this so I can understand this more clearly

If I use a chip and lets say hit a progressive by chance I can not get my winnings past what ever the free chip that I used?
