30 people solved that puzzle so far
6 of them abandoned it.
1 took almost 4 hours, I'll discount that one.
The fastest solving time for it was 2 minutes 16.991 seconds
(but as I see now, this was done by someone using an automatic solver)
The actual fastest was 3 minutes 7 seconds (but this was also by
someone who at the time was caught using an automatic solver).
So the actual actual fastest time was 3 minutes 40 seconds (by
pnm )
The average was about 8 minutes and 36 seconds
(not counting those top 2 times mentioned above)
