The main objective of Traffic Jam Fever is to navigate through congested roads and clear traffic by solving various puzzles. Players must strategically move vehicles to create pathways and prevent accidents.

Stars can be earned by completing levels quickly and with fewer moves. The faster you complete a level and the fewer vehicles you move, the more stars you will receive upon completion.

Traffic Jam Fever features a variety of vehicles including cars, trucks, and buses. Each vehicle has different sizes and movement capabilities that add complexity to the puzzles.

To progress to higher levels, you must complete the current levels successfully. After finishing a level with enough stars, new levels will become available, often introducing more challenging puzzles.

To solve puzzles effectively, consider the following strategies:
1. Analyze the current layout and identify key vehicles blocking the path.
2. Focus on moving larger vehicles first, as they block more space.
3. Look for combinations of moves that will open up multiple pathways at once.
4. Keep track of your moves to avoid unnecessary actions, maximizing your star potential.
