Yes, I totally agree with Phil Lamat.(posted 9613 days ago)* My zzyzzyxx high score is clean. For those who noticed something strange in my inp at 570330, I suggest you to spend less time writing on board and more time analysing the game ; if you're not too stupid, you will understand what happened and how the game is working.
* Thank you Chris Parsley for suspecting me of cheating without watching the inp file ! Congratulations !
