About this puzzle

A medium 15x15 grid in the weather theme, Rainbow 15x15 Nonogram hides a recognisable picture once the logic clicks. About 37% of the grid is shaded — 84 filled cells out of 225 — which makes for a fairly balanced board. The picture is left-right symmetric — solve one side and you can mirror the same logic across the centre column.

Its longest clue runs to 13 cells, so anchoring that block early gives you a reliable foothold. Budget about 2 minutes for a relaxed solve.

How to solve this nonogram

At this size, work the longest clues first, then use the cells they force to crack the shorter lines around them. With balanced coverage, alternate between filling forced cells and ruling out empties to keep both kinds of clue moving. Spot the symmetry early and you can copy solved sections to the mirrored side instead of re-deriving them. Use Check whenever you want to confirm progress, and switch on Challenge mode if you prefer catching errors as they happen.
