Did Conway pay the wager for either of the proofs to the The Angel Problem?
I'd check in on this every now and again when it was an unsolved problem and would like to know how the story ends. Anyone know more details?

Actually, until very recently, Conway didn't even believe his problem had been solved. (This despite the fact that multiple solutions have been published, some years ago by now, and the solutions had even been exposited at seminars at Princeton.) Only a few months ago did a few graduate students at Princeton convince him that the problem was solved. He was particularly excited when he heard about the "nice devil" (who never kills a square that could have been visited before). I have checked with Conway: the bet has not yet been paid. However, it will be soon. I will update this answer if and when it has been paid. 


If I remember well Andras Mathe told me that the prize was supposed to be split to four parts which would have made it 25 each, so he decided to renounce his part. 


According to Wikipedia, neither the proof that the 4angel can win, nor the proof that a 2angel can win, has been awarded the $100 yet.
