About this puzzle

A medium 30x30 grid in the transport theme, Train 30x30 Nonogram hides a recognisable picture once the logic clicks. About 35% of the grid is shaded — 318 filled cells out of 900 — 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 25 cells, so anchoring that block early gives you a reliable foothold. Budget about 10 minutes for a relaxed solve.

How to solve this nonogram

On a large board, divide it into zones: lock in the longest clues, mark proven-empty cells with X, and only then chase the tight lines. 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.

FAQ

FAQ

Which grid sizes can I play the train nonogram in?

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.

Does this puzzle save my progress?

Yes. Your moves and timer are saved in the browser after every action, so you can close the tab and come back later without losing anything. Each grid size keeps its own progress.

How do I check for mistakes?

Tap Check any time for a manual review, or turn on Challenge mode for immediate feedback as you play.

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.
