How to play

• Tap a square to clear it. A number counts the mines touching it. A blank clears its neighbours, but never a letter: those you tap yourself.
• Letters belong to hidden words on today's theme. Word squares never hold a mine, so once you can guess a word, the rest of it is safe.
• Hit a mine and GuffBot loses a life. Three and it's over. Stuck? A hint shows the shape of one unfinished word. Two a day.
• Right click, hold, or use Flag to mark a mine. Fewer taps and a quicker finish score more. Every board can be finished without guessing.
