Rules
- Several sets of attributes must be matched one to one (names × drinks × pets).
- Each clue gives a positive or negative link.
- The resulting combination is unique and satisfies every clue.
How to start
Draw a cross table
One attribute set down the rows, another across the columns, tick and cross as you go. It is the only efficient method.
Enter the absolute clues first
Anything that pins a value directly gets filled in immediately.
Finish by elimination
When a row has one slot left, it is true.
Where players get stuck
- Doing it in your head — these puzzles are close to impossible without a table.
- Treating relational clues ("next to") as absolute positions.
