So, I've heard that the Forge of Empires creators have tried hard to make it so a daily challenge is not impossible. It may still not be impossible but today's is pretty darn close! Collecting 2,500 tavern silver, I'd need to empty a filled tavern 4 times in order to get that. I think at most I've only managed twice and I'm online here several times a day on average. Well at least it isn't yesterday's. I was able to get the Challenger's Chest for the 2nd time and my 2nd Wishing Well. So yeah, it's not like I'm all that upset by today's. Just a little frustrated that I very likely can't get it. Usually I make it a policy in my main world to complete all daily challenges.
