Reading a Turning Route: Lines and Adjacency in Number Pop
A connection line shows the order of selected tiles. A route that looks visually smooth must still satisfy the adjacency rule.
A valid turn
| Column 1 | Column 2 | Column 3 |
|---|---|---|
| 1 | 2 | 5 |
| 4 | 3 | 4 |
| 2 | 5 | 1 |
Start at the top-left 1, move right to 2, down to 3, right to 4 and up to 5. Each move crosses one horizontal or vertical edge, so the turning route is valid.
A tempting shortcut
Jumping from the top-left 1 to the central 3 fails twice: it is diagonal and skips 2. Visual proximity is not enough. Locate the next two numbers before starting. You can also inspect a 3 and trace possible 2s and 1s backward while searching, but enter the route in increasing order.
What the line tells you
The line confirms selected tiles. Drag back to the previous tile to remove the last selection. If your finger hides a tile, check that the final number was selected before releasing. These are control explanations, not measured claims about visual psychology or reaction speed.
