Clue Castle
A book of “who has what?” logic puzzles. Each room has a few characters, things to match them with, and picture clues that lead to the one answer that fits every clue.
- Rooms
- 60 in five towers
- Extras
- Picture Sudoku, endless Courtyard
- Clues
- Pictures with a sentence, read aloud
How it plays
What your child does
- Tap a square once for ✗ (“not this one”) and again for ✓ (“yes”).
- Auto ✗ crosses out what follows from a ✓, shown dashed for a moment so your child sees why.
- Solve checks the board. A wrong answer is never revealed: the game names one clue the board disagrees with.
- Hint first points to a useful clue, then shows a faint mark, then places it.
Inside the castle
Five towers
Each adds a kind of clue: yes/no, linked pairs, left/right, either/or, then two-step clues.
Courtyard
A new puzzle every time, using only clue types your child has met.
Picture Sudoku
4 × 4 and 6 × 6 boards with pictures instead of numbers.
For grown-ups
Good to know
- Marks are kept if your child leaves in the middle of a room.
- The towers open with stars, so there is always something new to aim for.
- The home screen shows Clue Castle to children aged 8 to 10. You can turn it on for any child in the Parent Zone.
- The game saves itself, so your child can stop at any time and pick up where they left off.
