2019 Flare-On Challenge Solutions

We are pleased to announce the conclusion of the sixth annual
  Flare-On Challenge. The popularity of this event continues to grow and
  this year we saw a record number of players as well as finishers. We
  will break down the numbers later in the post, but right now let’s
  look at the fun stuff: the prize! Each of the 308 dedicated and
  amazing players that finished our marathon of reverse engineering this
  year will receive a medal. These hard-earned awards will be shipping
  soon. Incidentally, the number of finishers smashed our estimates, so
  we have had to order more prizes.

The U.S. reclaimed the top spot of total finishers with 29.
  Singapore strengthened its already unbelievable position of per-capita
  top Flare-On finishing country with one Flare-On finisher per every
  224,000 persons living in Singapore. Rounding out the top five are the
  consistent high-finishing countries of Vietnam, Russia, and China.
