## Basic Ideas

Clicking a track square will place either an unknown track piece or a cross.

Clicking between the squares will force a track direction, once there are exactly two track directions the system will place the correct track piece.

**Note:**the track piece cannot be changed if there are exactly two track directions.There is only one start and one end to the track.

## Walkthrough

Step 2

As this is 4 x 4 puzzle we know that every square in these columns is a track piece (but we're not yet sure in which direction). Clicking the squares will place an unknown track piece.

Step 3

As this is a corner square, there is only one possible direction for the track to take, so we can click between the track squares to force the direction.

As this is a corner square, there is only one possible direction for the track to take, so we can click between the track squares to force the direction.

Step 4

Forcing the corner direction means that the track must leave the corner to the right, which means that this 1 clue is now satisfied and all of the other squares in this column cannot be track pieces, so we can place an X in each.

Step 5

These clues can only be satisfied in one way, so we can place track pieces and X's as required.
