How to play: 1. Draw a line on white paper with a plain dark crayon or marker. 2. Install the battery and turn it on. 3. Place the mini truck with the line drawn. 4. The train will automatically run on the line. Tips: 1. Draw lines on the whiteboard and white paper with a pen, and when (the switch is on in the lower part), the car can sense the black line and drive along it. 2 When the line is too thin, the car may run out of the line. When the car is running at the end of the line, it can continue to drive in that direction. 3. If the car is driven in the wrong direction, the battery may be mounted on the opposite side. Please reinstall the battery according to the correct method (one side of the battery should be connected with the spring part) 4. Please do not leave the car in the sun, under fluorescent lights, or shiny paper to avoid damage to its sensors by bright light.
