Printable Alone
Printable Alone puzzles
Alone is a shading puzzle on a number grid. Shade cells so no number repeats in a row or column. Shaded cells cannot share an edge, and the clear cells stay connected.
Shading the number grid
- Shade removed numbers with pencil or a highlighter.
- Circle or mark numbers that must stay clear.
- Scan both the row and column before shading a duplicate.
How to play
Shade cells so no number repeats in a row or column. Shaded cells never share an edge, and the unshaded cells stay connected.
For a longer walkthrough, see the Alone rules page.
Checking duplicate numbers
Have students point out the duplicate pair before they explain which copy should be shaded. Remind them to check shaded neighbors and clear-cell connections too. Keep the answer key separate. More Alone boards are available at LoopAndGrid.com after class.
