Game Objective

Draw borders to split the grid into regions. In each region, every square must be reachable from the others by moving up, down, left, or right; touching only at a corner does not connect squares. All regions must have the same required number of squares. A number in a square tells how many of that square's four sides must be drawn as borders.

Divide the grid into equal-sized areas in accordance with the clues.

How to Play

Left-click an edge between squares to mark it as a border between two regions.
Left-click again to make it undecided.
Right-click an edge to mark that there is definitely no border there, meaning the two squares are in the same region.
These puzzles reward careful deduction more than speed. Start with the most constrained clues, eliminate impossible choices step by step, and avoid guessing unless the puzzle specifically calls for it.

Beginner Tips

First check the required region size for the puzzle. Every finished region must contain exactly that many squares.
A 0 clue means none of its four sides are borders. A 4 clue means all four sides are borders.
Use no-border marks too: if two neighboring squares must belong to the same region, marking that edge as not a border prevents later mistakes.
