How to read a 3×3 logic grid

A Rulessa board contains nine tiles arranged in three rows and three columns. The goal is not to match one hidden picture. You are arranging the tiles so that all six line clues are true at once.

Each tile has three independent features

• Colour: Green, Yellow, or Red.
• Shape: Circle, Square, or Triangle.
• Pattern: Solid, Striped, or Outline.

A red striped circle is one tile with three separate values. A clue may care about only one of them.

Rows read from left to right

The clue card beside a row applies to its three horizontal tiles. Follow its arrow across the grid and compare only the feature named by each condition.

Columns read from top to bottom

The clue card above a column applies to its three vertical tiles. A tile that looks right for its row can still be wrong for its column, so always consider both directions.

Intersections connect the clues

Changing one tile affects exactly two lines: its row and its column. That is the central idea of the grid. A strong move helps both intersecting clues or fixes one while preserving the other.

A simple reading order

1. Scan all six clues before moving anything.
2. Mark mentally which lines need three matching values, three different values, or one pair.
3. Notice rows or columns with two conditions.
4. Find tiles that could satisfy both their row and column.
5. Swap only after you can name the clue you expect to improve.

There may be more than one valid arrangement

Rulessa accepts any board that satisfies every clue. You are solving the rule system, not trying to reproduce a single secret layout.
