Here is the solution for Nonocross Level 1. Use the clues around the grid to check which cells are filled.
Square
| 3 | 11 | 3 | |
|---|---|---|---|
| 3 | Filled | Filled | Filled |
| 1 1 | Filled | Empty | Filled |
| 3 | Filled | Filled | Filled |
Level 1 solution: fill every cell around the outside and leave the middle cell blank to form a square.
How to solve Nonocross Level 1
Each row clue shows the groups of filled cells in that row. The top and bottom rows show 3, so fill every cell. The middle row shows 1 1: fill the first and last cells and leave the center blank.
The column clues confirm the same pattern: the first and third columns are filled from top to bottom, while the middle column has filled cells at the top and bottom with a gap between them. The green cells in the grid are the answer; X marks for empty cells are optional.
