Out of Range is a variant Sudoku using Lockout Lines.

Sudoku:
Place the digits 1–9 in every row, column, and 3×3 box, with no repeats.

Lockout Lines:
Digits in the diamond endpoints of each Lockout Line must differ by at least 4.
Digits in the interior cells of a Lockout Line must lie outside the numerical range defined by its two endpoint digits.
Where Lockout Lines intersect, each line continues straight through the intersection.
