I have never heard of them expiring. Let this be a lesson to all of you. Use your freeplays before you bet real money. I hate using them because you HAVE to find half point lines so I don't bother to add that to my handicapping equation. Freeplays at Betdsi expire after 180 days. I thought that they were earned currency that I could use whenever I wanted. Just a kick in the gut. Be forewarned. I was so looking to this football season and racking up, now I am already 800 dollars in the hole. Dammit!!!!! It's always something
