How to play

Draw one railway line from the engine at A to the station at B.
Each number counts the dots the line passes through in that row or column.
The line goes across or down, never diagonally, and never branches or crosses itself.
The black pieces are already laid.

Controls: drag from dot to dot to lay track; drag back over it to remove it. Tap a dot to cross it out. On a keyboard: arrows move, Shift + arrow lays track, X crosses out.

The crossing rule

Draw an imaginary line between two rows (or two columns). If A and B are on different sides of it, the track crosses it an odd number of times. If they're on the same side, an even number. When only one crossing point is left open, the rule tells you whether the track uses it.
