Each month is one giant crossword. Each day one numbered area is today's area: finish it for a 100-point bonus, then keep traveling as far as you like. Bonus areas ring the outside of the map, worth 50 points each. Solve a word to clear the fog around it. Tap a square to choose a clue. Tap the same square again to switch between across and down. Drag to move the map, and pinch to zoom.
