Calcudoku.org appears to be 1000 days old today. Congratulations Patrick (and original members).
Thanks
I should write a short history of the site somewhere.
I wrote the original version on Tuesday, February 10th, 2009: I read about "kenken" in
the New York Times in the morning, liked the puzzle, and decided to try and create a site
(really a generator, solver, site code, database, etc.) in
one day By the evening I had a site (then at
http://www.patrickmin.com/kenken) with puzzles in
three sizes (4x4, 6x6, and 8x8) and two levels ("Easier" and "Harder").
Found a screenshot on the "wayback machine":
(I was still using "kenken" there, at some point I got a "cease and desist" e-mail
from the trademark holder)
Some time in November 2009 people could submit their e-mail address after solving a puzzle,
in anticipation of an accounts system.
The accounts system started January 7th, 2010 (with first accounts for pnm (me), min (my dad),
cov, pcarless, mparisi, mpopeskov, amshamay, hopingcc, ...)
So the site really is 1331 days old
Patrick
