This game is about assisting a car to create a bridge for it to be able to safely cross to the other side. To create a bridge, tap the screen and drag across. But be cautious as there is only one change to draw a line. 

This is very easy to play. Just tap the screen to start drawing then hold and drag across to make the shapes or design you want. Once done, release your finger and the car will run. You will just need to wait for the result if it is successful. 

If you failed, no worries, you can try again as you will get unlimited answers to each lever and there is no limit on each game.
