Fish Nonogram

Play Fish Nonogram online

Play Fish Nonogram online free: reveal ocean pixel pictures with row and column clues. Solve 90 fish and reef puzzles in 5x5, 10x10 and 15x15 grids. The ocean collection has 30 original pixel motifs, including reef fish, jellyfish, turtles, coral and shells, each available at three grid resolutions.

This is a single-player picture logic game. Clues describe the picture; the numbers are not values to enter into Sudoku cells. Take your time: the clock records your solve, while Pause stops it when you need a break.

How to read nonogram clues

Read each line’s clues in order. A single 3 means one uninterrupted group of three filled squares. Two clues such as 2, 1 mean a two-square group, at least one empty square, then a one-square group. The rest of the line can contain additional empty spaces.

For a five-square row with clues 2, 2, the groups and their required gap use every square: fill the first two, mark the middle empty, then fill the final two. For clue 3 in a five-square row, every possible placement covers the middle square, so that square is a safe first deduction.

Use rows, columns and empty marks together

A filled square contributes to both its row and column. Compare the two sets of clues before expanding a group. After locating every filled group on one line, mark the remaining spaces with × to keep track of what you have ruled out.

Fill and × Mark are separate tools, and Erase returns a square to unknown. Dragging paints one stroke using the selected tool; Undo reverses that whole stroke, while Redo puts it back. Keyboard players on desktop can move with the arrow keys and use Space, X, E, Z and Y. On touch screens, choose a tool and tap or drag across the grid.

Logical hints and checking mistakes

Hint examines legal placements using your current marks. When every valid arrangement agrees about a square, it explains that forced filled or empty step. You can apply it or close the explanation and continue yourself. If marks conflict, the hint can tell you which line needs another look.

Check highlights filled squares that should be empty and × marks on solution squares. It does not erase your work. Each use is counted in the completion summary, and you can undo or erase the relevant marks. The game does not replace its clue system with a guessing or lives mode.

Start with a small nonogram picture

Fish Nonogram begins with a mostly completed 5×5 picture and three filled squares left to find. Follow the highlighted clue to finish the lesson, then solve an easy 5×5 picture yourself. Later, the reef challenge gives you a 10×10 grid with more clues to cross-check.

Use the clues, not a guess

Each number describes a consecutive group of filled cells. Separate two groups with at least one empty cell, and compare a row with the columns that cross it. A completed line helps you mark spaces that cannot belong to the picture, making the next clue easier to read.

This picture logic puzzle on FoolFish Games suits a short browser break: the first boards are small, and the larger grid comes after them. For another clue-based game, try Fish Sudoku, or browse more puzzle games for Chromebook.
