One Up Puzzle

A number-placement logic puzzle on a square grid divided by walls. Every horizontal and vertical run of cells between two walls must contain the numbers from 1 up to its length, with no repeats, so a two-cell run holds 1 and 2. A new numbered grid is published daily, and cells are completed through pure deduction.
