Children's Ward

This used to be a children’s ward, but the walls are now covered by scribbles and various shapes, probably the work of the children’s ghosts. Examining the floor tiles, you discover a cryptic pattern that indicates that Ken has likely been here, twice.

• Each symbol (the mathematical operators +, -, x and / do not count as symbols) represents a different digit from 1 to 9.
• Each grid should be filled with the same six symbols used in the clues for that grid (rather than the digits 1-6).
• Other than the above, regular KenKen rules apply.
