I will send you an email about the prize...

The other five best results are:

derez - 51ms

boten - 66ms

Rui - 102ms

ertuncb - 113ms

I've tested the two best solvers many times and the results were consistent.

I've asked corwin42 to explain his solution which looks pretty complicated.

The fastest solver and the puzzles are attached.
