How to play
Each row and column holds every number exactly once. A sign between two cells always points at the smaller of the two — so < means the left cell is smaller, and ∧ means the cell above is. A few numbers are printed to start you off. Use Pencil for candidates and Fast Pencil to fill in the ones you have not worked out. If you have already pencilled some cells it asks whether to fill only the blank ones or rewrite them all.
