🧩 HOW TO PLAY

Each puzzle consists of a grid filled with numbers.

You must black out some cells while keeping others white, following three simple rules:

No duplicate numbers are allowed in any row or column among white cells.

Black cells cannot touch each other horizontally or vertically.

All white cells must remain connected as a single group.

That’s it.
