Reveal the picture through the clues

The theme may suggest tentacles, fins, shells and wave lines. Use that idea when observing the finished image, but decide every cell from its row and column clues. Do not fill a shape simply because you expect it.

After the activity

Separate living things from landscape features; explain why a whale is not classified as a fish. Explore sea animals and ocean scenery through words, shapes and routes.

Separate empty from unknown

Mark cells you know are empty with a cross and leave unresolved cells unmarked. Progress in a row supplies information for its columns. At the end, count the actual runs in every line and compare them with all its clues.
