Pixel Reveal

How to Play

keyboard_arrow_down

1. A pixelated image is hidden behind tiles. Tap tiles to reveal small sections.

2. Guess the image as early as possible — fewer tiles revealed means a higher score.

3. Type your guess and submit. The sooner you identify it, the more points you earn.

Expert Tips

Centre first: Reveal tiles near the centre — subjects are usually in the middle of an image.

Guess early: A correct guess with few tiles revealed scores far more than a late correct guess — commit to your theory.

Goal

Solve a nonogram (picross) puzzle. Fill in the correct cells to reveal a hidden pixel image.

The Clues

Each row and column has number clues. A clue of 3 2 means one block of 3 filled cells, then a gap, then a block of 2 — in that order.

Controls

Click a cell to fill it.
Right-click (or long-press on mobile) to mark a cell as empty with an X.
Use X marks to track cells you have logically eliminated.

Solving Strategy

Start with the longest clues — they constrain the grid most.
Any cell that must be filled regardless of the clue position can be filled immediately.
Cross-reference rows and columns to narrow down possibilities.

Why this sharpens your mind

Logical Deduction

Nonograms require systematic constraint elimination — if a cell must be filled in every valid arrangement, it is definitely filled. This trains step-by-step logical reasoning.

Spatial Reasoning

Visualising how blocks fit within rows and columns while holding constraints in mind exercises mental spatial manipulation, a strong predictor of STEM ability.

Patience and Concentration

Puzzles reward sustained, methodical focus — training the ability to resist impulsive guessing and think problems through completely.
