CHANCEMONOP
This game ended in 2010. Any unused codes will no longer be valid so none can be given.
If you find a code, please send it to me at mcd.monopoly@yahoo.com so that others may not use it before I do. Thanks! All you need to do is type in MCD Code in the subject box and that would be great. Don't throw away and waste your codes!
There are no hacks or codes for May but i think there will be some for June.
