You select what game you’re happy to trade for on each entry you have. That is to say unless you select your £60 game to trade for the £15 value one it isn’t happening. Now, human’s error so there is a grace period between the software running and the trades getting confirmed. The consequence of backing out the trade is to lose that item being available in future trades.
Oh, and ignore 90% of what a user enoon says in the discussion thread. With absolutely no apologies he’s a twat and knows it. His profile lists all his bans and why they were wrong. He’s more bothered about precise application of rules then getting the majority happy with trades.
And sometimes he makes a really good point, but by the time you know when that is you probably don’t need him to make it. I’ve had good conversations with him on other topics…
I’d add a refinement to this. Look at how many people/items wanted yours. If it’s 0 items just don’t list it again. However if there’s a reasonable number of items keep going. The algorithm has plenty of scope for not trading popular games just because they don’t fit in any loops. Took me 4 attempts to shift A Handful of Starts. Was popular each time. A friend recently took 3 attempts for Nusfjord. I put Herbalism in twice, no interest either time, I gave up.
I’ve actually had several games moved recently, both in and out, by looking at the untraded lists and contacting the relevant people with a money offer.
Protects you from getting two or more of the same game. I generally don’t care which of my games I trade for a specific game, so I’ll tick them all as valid trades for it, but if that game is offered by multiple people, and two of them wants some chain of trades that involves one of my games, I don’t want to end up with two copies of that game.
Unfortunately, math trades almost never happen here, there just isn’t enough interest. The one time I joined one, I traded my Japanese copy of Takenoko to someone, and got a meeple-upgraded English copy of Agricola from someone else. So, that worked out well, except for the fact that I don’t seem to enjoy Agricola much.
Hmm. Perhaps the UK Maths Trades are ran differently? I always use the OLWLG software to list my items for trade so I don’t have to worry about the formatting of the items
I had an issue with the OLWLG providing links to add items last time I participated in a math trade… I think it worked on my phone and not on my PC (and the same issue you mention, i.e. sending me to a login page), so I completed that step on my phone and did the rest via PC browser.
Note to others who may be interested in trades and my yammering makes it look impossible…once you know how it works it seems relatively simple.
The biggest problems I’ve had are
A) trying to use Chrome to add to the geeklist (apparently all other browsers are fine
B) the OLWLG doesn’t automatically update. When your own games are included it is very simple
Check for new entries periodically. Duplicate protection when cases arise. And, most importantly, click SUBMIT when the deadline for offers is done, and do it before the 2nd deadline. You are not in the trade if you didn’t submit.
