Want one more way to get some new games into your collection at WashingCon? Of course you do! As board game hobbyists a lot of us have collections brimming over with games we barely play any more. And the best way to find folks willing to trade games you want for the ones that just aren't making the table at your house any more is through a math trade. By signing up, listing the games you are willing to part with, and the games you are interested in trading for, the site's algorithm figures out the best way for the most games to be traded amongst participants. Then bring you games to the convention on Saturday September 8th, and exchange them for fresh, brand new (used) games! If you still have questions about the process, click the "learn more" button below for Board Game Geek's detailed primer. This costs you nothing except for your unloved games and few minutes of your time, so register now!
