Draw Shapes: Grid Puzzle

Draw a line across the cells to make a region, tap to erase. The board is solved when every cell belongs to a region and every region follows the rules.

FEATURES

Nine rule types, each introduced with a worked example:
- Required Shapes — match one of the shapes on the card
- Region Size — every region is exactly N cells
- Gems — one gem of each colour per region
- Shadows — a figure on a cell says what shape that region must be
- Size badges — a number on a cell says how many cells that region must have
- Shape Uniform — every region on the board is the same shape
- Unique Neighbors — regions that touch must be different shapes
- Similarity and Difference — two regions joined by a badge must match, or must not

Later levels stack up to four rules on one board.

Wooden bars between cells that no region may cross.

Instant feedback: a region that breaks a rule turns red as you draw it, and the marker it broke shows an X.

Hand-drawn art, no violence, nothing to read but the rules.
