The crossing game is played by clicking on each of the people on the sidewalk separately. Paying attention to the pedestrian cars you click on, it switches to the other sidewalk. The time it takes to move people to the other sidewalk appears at the top of the screen. On the side it looks like how many people you need to spend. There are arrows on the left and right sides of each road. If the road is a single lane, there is an arrow on one side. A 2-lane road is on both sides. Control both sides of the road and pass all the pedestrians to the other side, and you are not entitled to advance to the next part of the crossing game.
