Warm-up
Phase 1 · Build the walls
- Draw walls between neighboring numbers: up, down, left or right.
- Each number tells you how many walls touch it, including walls along the outside edge.
- Walls never close into a loop, and every wall connects to the border.
Draw the outside edge too: it’s all wall except at the two arrows. Drag across numbers to draw a wall; drag over it again, or tap it, to erase. Blue walls are given. A number turns green when it has the right count and red when it has too many.
Phase 2 · Walk the maze
- Enter at the arrow on the top edge.
- Move through the open squares. You can’t cross a wall.
- Leave by the arrow on the right edge.
Unlocks when the walls are finished. Drag the red marker through the maze; drag back over your line to undo it. Tapping squares and the arrow keys work too.
