What is Nonogram?
Nonogram is a logic puzzle developed by Konstantin Kornushin, originally released in October 2021. The core loop challenges players to examine numbers along grid axes, deduce which squares must be filled, and uncover a hidden illustration. Unlike reflex-driven games, this title focuses entirely on systematic elimination and spatial deduction. It plays free in the browser with nothing to install on Free Learning System.
Key features
- Number-based clues: Numerical headers positioned along each column and row define the quantity of active tiles to locate.
- Picture reveals: Accurately marking every designated cell completes the board and exposes a clean illustration.
- Dual fill modes: Players can left click to place marks or right click to switch the fill type during puzzle solving.
- Assistance system: Each board provides 3 hints that can highlight valid placements whenever progress slows.
- Continuous progression: Successfully solving a puzzle prompts the game to load the next challenge automatically.
- Flexible platform access: Built in portrait orientation for desktop and mobile web browsers without additional downloads.
How to play
- Examine the numbers positioned at the top of columns and the side of rows.
- Identify lines where clues indicate obvious placements without requiring complex deductions.
- Left click on targeted squares to fill them into the active grid.
- Right click to switch the fill type and adjust your marking approach.
- Cross-reference completed columns against rows to rule out empty spaces.
- Activate one of the 3 hints if you encounter an impasse on the board.
- Fill all required squares accurately to finish the picture and advance to the next level.

Grid deduction mechanics
Every board in Nonogram functions as a logic matrix where clues supply partial information about tile arrangements. Numbers indicate how many total cells need to be shaded in a given lane, but they do not reveal exact coordinates. Players resolve this ambiguity by testing intersections between horizontal lines and vertical columns.
Once a column or row receives all its required marks, any remaining squares along that line are guaranteed to remain unshaded. Noting these empty positions limits the options for perpendicular lines, sparking a cascade of confirmed cells. Steady deduction ensures progress without risking errors that could disrupt the overall solution.
Tips and strategy
- Start with highest numbers: Lines requiring the largest count of filled squares offer the most immediate certainties across the board.
- Verify perpendicular axes: Each time you mark a square, check the intersecting line to see if its target quota has been reached.
- Switch modes intentionally: Use right click to change the fill type so you can organize your deductions systematically.
- Rely on logic over guessing: Every puzzle is structured to be solved through pure deduction rather than random attempts.
- Conserve your hints: Because only 3 hints are provided per puzzle, save them for complicated late-stage deductions.
