Grim Reaper’s Age Guesser is the most popular game on Dan Zen primarily because Dan Zen has had the number one entry for Grim Reaper in Google.
You answer 13 questions and the Grim Reaper will guess your age. To see how the answer was determined, you submit your real age and it will show you.
Each question has a calculation that determines an age. If the question gets within five years of the actual age then its factor goes up by one else it goes down by one. In the end, the total guess is made by adding up all the answers multiplied by the factors and dividing by the total number of factors.
For a while, after being listed in Yahooligans for kids, the only question that worked well for ages under 13 was “when did you last climb a tree?” This question ended up with a factor of thousands. Things have balanced out a little since then.
Over 10,000 people have had their age guessed and the Grim Reaper guessed 5% correctly, 35% within three years and over half within 5 years.
