How this data is usedHelp
Each person has one item from each of two sets. No two people have the same item.
Every clue is true. Some name what a person has or does not have. Others connect two items without naming the person.
Every clue is needed. Removing one would leave more than one possible arrangement.
No clue states the answer by itself. You must combine at least two clues, and more at higher levels.
The clues that rule out the most possibilities come first. There is no time limit.
