Goal: find every letter of the five or six hidden words on today's theme.
Tap a square to clear it. A number counts the mines in the 8 squares around it, diagonals included.
Letters are never mines. Their small corner number counts the mines around them the same way. A grey 0 means every square around it is safe.
Mines cluster around the words, so read the numbers before you tap beside or past a word.
A blank clears its neighbours, but never a letter. Letters you tap yourself.
Flag a mine with a right click, a long press, or the Flag button.
Hit a mine and GuffBot loses a life. Lose all three and it's over.
Stuck? A hint shows one unfinished word, hangman style. Two a day.
Score: 700 for the board, 20 for every mine you flag, 50 for every life you keep, and up to 400 for a quick finish. Hitting a mine costs 150, a hint 50, a flag on a safe square 25. Taps are free.
A Guff game. New board every day at midnight UK time.
