Object: Avoid any collision of planes.
 
You are an air traffic controller at Frankfurt Airport.
 
First click the board several times. Each time you click, a new plane will appear at the border and start to fly across the screen. Clicking an empty square allows all planes to move one step into the direction they are pointing to.
 
Click a plane to steer it ninety degrees to the right. Watch out for the moment you need it!
 
The goal is to avoid collision at all times.
Two planes will collide when they end up in exactly the same place on the screen. Hence two planes on adjacent squares will not collide!
 
Two counters on the right border count your moves and your collisions.
 
I am pretty sure that after playing this game you will appreciate the stressful work even more which these air traffic controllers have to do...
 
Variant 2: Horizontally and vertically flying stealth planes. They are black and twice as fast.
Variant 3: Stealth planes flying into all directions.
