Fill the grid so every row and column holds each number once, while obeying every less-than and greater-than sign between the cells.

How to play
Each row and each column must contain the numbers 1 to N exactly once, like a Latin square. The inequality signs printed between neighbouring cells must also be satisfied: the open end always points to the larger number. Use the given numbers and the signs to deduce the rest.
No number repeats in any row or column
Every < and > sign between two cells must hold true
Duplicate conflicts and broken inequalities glow red as you play
The puzzle is solved when the grid is full and every rule is satisfied

Tips & strategy
Start where signs chain together, a cell forced below several others is often a 1, and one above several is often the maximum
A cell at the small end of a sign can never be N; the large end can never be 1
Use Notes to pencil candidates, then eliminate them as rows and columns fill
