Ok thanks! I wonder if the situation I had was a bug then. If I reproduce it I'll send a screenshot.

Recreated the issue - there was an 8 block in the top left (0,0) which is why the 8 block at (1,1) went grey. I deleted the top left 8 block using a 1 block, but the 8 block at (1,1) is still grey even though there aren't any more duplicates in range. 

Oh right, that must be it then. Briefly before submission I did noticed something strange with the score or the penalty system, but I couldn't figure out what or why, so at the last minutes I wrote a vague warning on the game's page that there would be bugs. You put so much thought into the game and even helped me find the bug and I really appreciate that!
