The math trade software will then be run at the close of the trade period, Midnight September 7. Using all the want lists from the participants as input, and the output it will create will tell everybody which of their games gets traded to whom, and what games they will be receiving from whom. The important thing to note about a math trade is that you will always receive a game you ask for whenever one of your games gets traded away.
You will never get a game you don’t want in return. However, if you are offering a game for trade that nobody else wants, it won’t get traded, and it will still be yours.
In-Person Trade will take place on Saturday, September 12th at 8:00am at the Milwaukee Marriott West
The Strong Tower Gaming Convention is offering an opportunity for attendees to trade their unloved games for games that they hope they can give some love to. This will be a no-shipping trade where games will be exchanged in person at the convention. The program will be set up and run in advance through BoardGameGeek.com and is called a Math Trade.
What is a math trade and how does it work?
A math trade is a game trade organized among several people, where person A gives a game to person B, B gives a game to C, …, and Z gives a game to A, completing a loop. Several of these trade loops of different sizes can occur, and the software that creates the loops tries to get the most number of trades as possible.
On BoardGameGeek.com, a Geeklist will be created where participants list what games they would like to trade away. When the submission period for people to add games to the list ends, then the want list submission period opens, where the participants say what games they want to receive for each game that they want to trade away. It is encouraged to put many games on the want lists of each game being traded away, in case your first choice of games to receive for it isn’t available.
