Choose a Board Size
PipeTrio is one game at four sizes. The rules do not change when the grid does. Connect each pair of matching dots, leave empty cells if no pair needs them, and do not let the lines cross. What changes is the number of cells, how many pairs share them, and how easy the dots are to hit.
| Size | Cells | Colors | Sitting | Suits | Phone |
|---|---|---|---|---|---|
| 5×5 | 25 | 3 or 4 | A minute or two | Learning the drag | Easy to tap |
| 7×7 | 49 | 5 or 6 | One short sitting | Everyday play | Comfortable |
| 10×10 | 100 | 12 to 16 | A focused sitting | When pair order matters | Tight |
| 13×13 | 169 | Many short pairs | A long sitting | The largest board | Cramped |
The sitting column is a guide for a first clear, not a recorded average. A 5×5 board is often a minute or two, which is why it is the one to learn on. A 7×7 board is one short sitting and still comfortable in one hand. A 10×10 board is a focused sitting, better on a desk than on a narrow phone. A 13×13 board is the long one, and the dots are the smallest, so a phone can feel cramped.
A smaller board is not a worse puzzle. It is a shorter one. Pick the size that matches the time you have and the screen you are holding. Each size page lists 100 levels and opens on that grid. On any play page, the buttons above the board switch size without a reload. This page is only the comparison, so the four choices sit together. It does not replace those pages, and it is not a fifth puzzle.
