Highway Merge
Join a fast road from a slip road. Cars are already passing in the lane you want, so you have to get up to their speed on the slip road, find a gap and move across before the road ends at the barrier. Too slow and you cannot fit in; too late and you run out of road. Six levels of faster and busier traffic.

How to play
- Drive with the arrow keys or the on-screen pedals. You start at the bottom of the slip road. Accelerate hard along it: the traffic on the road above is passing at the speed shown by how fast the blue cars move.
- The Gap ahead and Car behind readouts show the nearest cars in the lane you want. Look for a gap of three or four car lengths, match the speed of the traffic and steer across smoothly. Do not turn sharply at speed.
- Merge before the barrier at the end of the slip road, then drive on to the yellow exit marker at the end of the road. Hitting a car or the barrier costs damage, and too much ends the run.

Tips and strategy
- Get your speed up before you look for the gap. Merging at 40 km/h into traffic doing 80 forces the cars behind to brake, and is the most common mistake.
- Look over your shoulder, in the readouts: a car coming up behind at your speed is the one to watch. If it will arrive just as you move, ease off and fall in behind it instead.
- A lane change takes distance. At highway speed, the car moves about thirty metres along the road while it moves four metres sideways, so start earlier than you think.
FAQ
- Why must I match the speed of the traffic?
- Because the gap in a moving stream of cars is only a gap while you move with it. If you are slower, the cars behind close the gap before you reach it, and if you are faster you pass through it. Matching speeds keeps you in the gap.
- Why does the slip road end in a barrier?
- A slip road is designed to give you just enough length to reach the speed of the traffic and find a gap. If you could drive along it for ever, there would be no pressure to decide, which is the skill being tested.
