How to solve
- Latin square: Each number from 1 to N appears exactly once in every row and column.
- Cage maths: The numbers in a cage combine to the target with the operation shown (+, -, x or ÷).
- Single squares: A one-square cage simply gives you its number.
- List the options: Write down the number combinations that fit a cage, then let the rows and columns rule them out.
