Game Instructions & Description
How to Play Nonogram
Play nonogram puzzles online for free on desktop or mobile with no download. This version was made by the CrazyArcade team, and every picture was designed by hand. There are 50 puzzles in three sizes: 18 Easy puzzles on a 5x5 grid, 16 Medium puzzles on a 10x10 grid and 16 Hard puzzles on a 15x15 grid. Each one was checked with a line solver, so every puzzle has exactly one solution and can be finished with logic alone, without guessing. When you solve a puzzle, the game shows the finished picture and its name, such as a sailboat. The numbers beside each row and above each column give the lengths of the filled runs in that line, in order, with at least one empty square between runs. Click or tap a square to fill it, or drag in a straight line to fill several at once. Right-click, or switch the Fill/Cross button to Cross, to mark a square you know is empty with an X. Clue numbers turn grey once their run is complete, a small preview in the corner shows your picture so far, and an optional setting crosses out the rest of a line automatically when its fills match the clue. Undo steps back one move or drag at a time. A puzzle is solved when the filled squares match the solution, and X marks are ignored. The Check button shows wrong fills and wrong X marks in red, but a puzzle solved after using Check does not count toward your best time. The game keeps a best time for each size, a solved mark for each puzzle in the puzzle list, and your progress on every unfinished puzzle from the list, plus the latest random puzzle for each size, in your browser. The Random option builds a new grid for any size, about 55 percent filled, and keeps generating until the same line solver can solve it, so random puzzles also have one solution.
Controls & Interaction
Mouse click or tap: fill a square, or clear it if it is already filled Drag: fill or clear several squares in one row or column Right-click: mark a square with an X, or remove the X Fill/Cross button: choose what a tap or click does on touch screens Arrow keys: move the keyboard cursor Space or Enter: fill or clear the square under the cursor X: mark or unmark an X under the cursor U or Ctrl+Z: undo Escape: close the puzzle list or the restart prompt
Pro Tips to Win
- Start with the biggest clues. In a 10-square line a clue of 8 must cover the middle 6 squares wherever it sits, so you can fill those right away.
- Mark squares you know are empty with an X. Crosses split a line into smaller gaps, and a gap too short for any remaining run must stay empty.
- Lines with a clue of 0 are completely empty, and a line whose runs plus the single gaps between them add up to the full width can be filled straight away.
Frequently Asked Questions
Q: Does every nonogram here have only one solution?
A: Yes. All 50 hand-made puzzles were checked with a line solver that fills in every square using row and column logic alone, which also proves there is only one answer. Random puzzles are only accepted when the same solver can finish them.
Q: Why did my best time not save?
A: Best times are only recorded for puzzles solved without the Check button. Using Check marks the puzzle as assisted, so the solve still counts in the puzzle list but not as a best time.
Q: Is my progress saved?
A: Yes. Each unfinished puzzle from the list keeps its squares, timer and check count in your browser, and so does your latest random puzzle for each size. You can switch puzzles or close the page and continue later. Solved puzzles get a check mark in the puzzle list.
