Traffic Jam: clear the blocking chain
Look at the car blocking the exit, then at the car blocking that car. Solve the dependency chain before moving the red car.
Stay in each lane
Horizontal cars only move left and right; vertical cars only move up and down. A move cannot cross another car or leave the board.
Make temporary space
A useful move may appear to move a car away from the goal. It can create the room a different blocker needs.
Check the exit before spending moves
The red car wins when it reaches the right edge. Fewer legal moves earn a higher score; moving an already clear car rarely helps.
