We've finally got the math trade warming up for the convention.
Don't let the word "math" scare you away; it refers to the computer algorithm that calculates out the trades.
In a math trade, you post games or other items you want to trade off. Once everyone has added their items, you post what items you would like to trade your items for. Each possible trade is approved individually. For example, if you had a $5 card game and a $120 collectible board game you wouldn't want to trade both for another $5 card game. You can say "yes" to one and "no" to the other.
After everyone has posted their "wants" the computer calculates all trades and tries to create the most trades possible. Instead of a one item for one item trade, it will probably generate trade circles where everyone passes an item onto the next person. Last year I was in a 34 person trade circle.
Now, you don't have to know everyone in the trade circle. The program will tell you to give your item to one person and that someone will be giving you another item.
The more items people post, the larger the trading pool.
