Connect the dots along the grey lines, using the following rules:
- Every dot must connect exactly 3 lines.
- Every cell (area enclosed by black (half)lines) contains at most one number.
- Every number must be inside a closed cell.
- Every number is in proportion with the size of its cell. Ex: a cell containing the number ‘3’ must be 3x larger than a cell containing the number ‘1.’
Diagonal lines can cross. The puzzle can be solved without guessing. There is only 1 solution.
