Advanced clue

These values share a remainder pattern

Also known in the clue library as Parity/Modulo (quantitative).

parity-modulo

Clue pattern: Two values must match or avoid a parity or modulo bucket.
What to mark first: Group the ordered values by parity or remainder, then eliminate incompatible pairings.
Common mistake: Trying to compare exact values before using the bucket pattern.
Mini-example: Mina and Theo have table numbers with the same parity.
Print-book tip: Write the value buckets first: odd-even, or remainder classes.

When and where this clue pays off

Two questions matter more than the pattern itself: does this clue give you everything now, or only later — and does it become a mark on the board, or a note you have to keep separately?

Builds as the board fills in

Sort the values into their buckets first. The useful eliminations follow once one side is partly pinned down.

Marks the board directly

The bucket eliminations show up directly as marks.

Reading the clue is half the job. These are the methods that turn it into board progress.

Reading
Set Complement

Reading a 'one of these' clue as a statement about everyone outside the named set, not just the set itself.
