I assume anyone who searched this knows how to do it so I won't put how. I WILL put which keys to press and stuff. To mark a square with 'X' press 3 To break a square press 1 To undo either action, press 2 After each of theses actions, click the square you want to change. If a broken square shows up with an 'X' that means it's not supposed to be broken. If a 'X'-ed square is marked with a red 'X' its not supposed to be 'X'.
Just to be clear, on the bars that say 2 2, 1 1, 2 2, 1 3, 1 3, 2 2, it is NOT 22 or 11 etc. it is 2 and 2 or 1 and 1. One more thing, the picross is just a random shape not anything specific. Have fun! Comment if you want/need me to add more. -Dawnwing64
