Everybody then studies the big list and makes a wish-list of things that they&#8217;d be happy to receive in return for the stuff that they&#8217;re &#8220;donating&#8221;. All the wish lists are then fed into a magic computer program which runs a neato algorithm designed to make the maximum amount of people happy. You are then issued with an instruction: Send your (thing you wanted to get rid of) to (person X), and (person Y) will send you (something nice that you wanted to receive). <\/p>\n<p>The clever bit is that the person you&#8217;re sending to isn&#8217;t necessarily the person you&#8217;ll be receiving from &#8211; there are lots of little loops of senders and receivers &#8211; but the algorithm makes sure everything works out right in the end&#8230; everybody gets something they wanted. Or, in a worst case scenario, you&#8217;ll end up sending nothing and receiving nothing&#8230; but that only happens if you&#8217;ve been particularly fussy \/ unrealistically ambitious with your particular combination of donations and wants, and the algorithm couldn&#8217;t come up with a solution to please you.<\/p>\n<p>Obviously, there&#8217;s a huge trust aspect to a Maths Trade. The whole thing would go horribly wrong if somebody didn&#8217;t despatch an item that they were supposed to despatch, or lied about the condition of their contribution, or whatever&#8230; but &#8211; in the board game community at least &#8211; that kind of thing doesn&#8217;t seem to happen very often. The trade I took part in resulted in 235 items changing hands, and it all seems to have gone pretty smoothly.<\/p>\n<p><strong>TLDR version:<\/strong> Maths Trades are some kind of swap-shop voodoo magic, and this week I managed to swap the copy of <a href=\"http:\/\/boardgamegeek.com\/boardgame\/43152\/assyria\" target=\"_blank\">Assyria<\/a> (which I was a bit luke-warm on) for a copy of <a href=\"http:\/\/boardgamegeek.com\/boardgame\/21441\/mykerinos\" target=\"_blank\">Mykerinos<\/a>&#8230; (which is, IMHO, a far, far nicer game). <\/p>\n<p>I can imagine Maths Trades getting pretty addictive&#8230; it&#8217;s kind of exciting putting together your wants list, not-quite-knowing whether your trade will go through, and wondering which of your selected items you&#8217;ll ultimately get.
