Games and mouse problem

[Dr_s99]

Hi everyone!
I have a problem with my mouse and that is my scroll wheel doesn't work, in games or even in linux itself.
is there any way i could fix this?
if there is please tell me!

i have a Labtec Optical Mouse


and my secound question is what games are available in linux?
could you please name them and if you could in bracket after the name say if it is free or not, or give the link to the main web page.

Thank you
