Split every board into regions until each one obeys the level's own rule.
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.
