Decription[]
Checkered Fillomino is a variant of Fillomino, in which polyminoes are entered into a grid.
Rules[]
The objective is to add numbers to all cells, subject to the following rules:
- All numbers on the grid must be part of a polyomino of the same value.
- No two polyominoes of the same value can touch horizontally or vertically.
- Givens may be part of the same polyomino, conversely not all final polyominoes may start with a given.
- There must exist a way to shade some regions such that shaded regions neighbour only unshaded regions and unshaded regions only neighbour shaded regions.
Example[]
