Traffic Jam

How to play Traffic Jam

1. The red car must leave the parking lot through the exit on the right.
2. Drag a car or truck along its own direction: horizontal ones slide left and right, vertical ones up and down.
3. Vehicles cannot turn or jump over each other.
4. On a keyboard, tap a vehicle to select it, then use the arrow keys.
5. The goal shows the smallest number of moves for this jam. Undo, Reset and Hint are always there.

Tips

• Start from the red car and ask: what blocks it, and what blocks that?
• Trucks take three squares: free their path early.
• Sometimes the best move goes away from the exit, to make room.
• A vehicle slid several squares in one go still counts as a single move.
• Hint makes the next vehicle of the shortest route glow and tells you which way to slide it. The diamond badge is for jams cleared without Undo, Reset or Hint.

About Traffic Jam

Traffic Jam is a sliding block puzzle inspired by the rush hour of a crowded parking lot. It is pure planning: you can see everything, but every move changes what the others can do.

Each jam is built vehicle by vehicle, keeping the one that makes the solution longest, then solved by a computer to measure its real difficulty. Four levels go from a few moves to a packed parking lot that takes twenty moves or more.

Points and badges

Finishing a game of Traffic Jam earns points for your level. Four badges are waiting in this game, from bronze to diamond: each one says what to do and adds bonus points.
