So, we all know the apato fossil seems to offer the best trade value for DBs. So the theory has been to keep only those in your market and no other decorations or buildings to try and force the TH to give you fossil to DB (or food, DNA etc.) trades. But most of the players that post about getting lots of trade offers for the fossil this way also get rid of all their creatures and mods so that the TH can’t use those for trades. For those of us that really need to keep these instead of selling them off, the question then is, is there a better strategy?
I’ve been working on finding out if I end up getting more trade offers for structures to DBs if I keep more types of them in my TH. My theory is that the TH looks at the different things it can draw trades from and randomly picks from those, then randomly determines the trade. So if for instance, you don’t have any creatures or mods, you have a very high likelihood of a decoration being picked and with the fossil being the only one, that’s the one it will have to use.
If however you have LOTS of different mods and creatures, and only have that ONE decoration, you have a far lower chance of it being picked for a trade, than if, for instance, you have 4 or 5 types.
So I’ve started to keep not just a bunch of fossils, but at least also Hammond statues, and then either some Arches, or even better, any of the VIP structures (the wildlife preserve seems to be my best performer of these, not counting clock towers, which I would never trade!) So when ever I get a trade of coins for VIP buildings, I take it and use those for trades for DNA, DBs and food.
This definitely has greatly improved my numbers of DB offers every day… the individual amounts I get may not be as good as the fossil gets, but they are reasonably close and it really only takes getting 1 or 2 extra ones that I might not have otherwise gotten to make it worth while doing! Particularly since it can often be days before I see a DB trade for the fossil.
I’m still testing out whether the actual amounts of the structures I have in the market may make a difference… that is, can I improve my chances to have it use the fossil by keeping more, or possibly less, of that in the market than the other choices?
Curious of what anyone else might have observed on this topic.
