Reading the Answer
■ = filled square. · = empty square. Fill the marked squares in the game; an X, where supported, only marks a square that stays empty.

Check Two Clues in This Grid
Row 1 has the clue 1, 1, 1, 1. In the completed picture, that row reads ■··■·■··■·. Its uninterrupted groups of filled squares match the clue in the required order.
Column 1 has the clue 1, 2. Reading downward gives ■···■■····. The filled-square groups match the column clue, confirming that this part of the picture is consistent.

Why Several Grids Fit These Clues
This puzzle has 2 clue-valid arrangements. Across those arrangements, 96 cells keep the same filled or empty state, while 4 cells can differ. The stored grid shown above satisfies every clue, but the clues alone do not force that exact picture.
Highlighted cells mark positions where another clue-valid arrangement may differ. They are not errors in the displayed answer.
