First of all, please do not post in the thread when you've got this sort of concern, but send a PM to the contest assistant or manager that runs the contest.
However, you did raise a valid concern : I obviously was not sufficiently awake when I added LadyNimue's answer, as I came up with 53 instead of 51. I'm going to update the results accordingly.
As there may be several solutions for each trail, I am accepting the first valid solution for each of the grid.
I'm going to clarify the rules to say "The first correct answer for each of the 9 grid will be rewarded" instead of "The first 9 correct answers will be rewarded".
