Puzzle and Goal
An unsolved puzzle consists of a square grid with some number clues in it.
The goal is to place numbers in the blank cells to satisfy the clues.
Rules
The solved grid must satisfy the following conditions:
Each rank will have the same number of blank cells. No number appears twice in the same rank in the solution; use the numbers from 1 to N, where N is the number of blank cells in each rank.
The clues represent the total of the neighbors of the clue cells (not including other clues).
