Ok, really? You're on the hardest puzzle page of the entire site, and you hit the help button?

Watch the first 90 seconds of the video for full rules. Fill the board with teal or black cells. All teal squares must connect; black cells can’t touch; teal squares can’t be trapped.

Numbers show how many teal squares are connected (including itself); the small number shows how many more are needed. Cells turn red if a move makes the puzzle impossible.

100% scored if you reached any valid solution (with the right # of black and teal squares). Use “reveal a square” sparingly! Good luck!
