About this puzzle

A easy 15x15 grid in the fish theme, Fish 15x15 Nonogram hides a recognisable picture once the logic clicks. About 35% of the grid is shaded — 78 filled cells out of 225 — which makes for a fairly balanced board. The picture is top-bottom symmetric, so the lower half echoes the rows you work out up top.

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.

15x15, 20x20, 30x30, 40x40. Smaller grids show a simpler outline and take a few minutes; larger ones add detail and turn into a longer, more careful solve.

How do I check for mistakes?

What do the X marks do?

X marks flag cells you've proved are empty. They don't affect the solution, but they make bigger grids much easier to track.
