Transport and Logistics Puzzle

Objective

Help all of these trucks to cross the bridge within 30 minutes. (Note: Gameplay has been sped up so you don't have to play for 30 actual minutes).

Rules

• Only one or two trucks can cross the bridge at the same time.
• They can travel in either direction.
• Each truck has a different speed to cross the bridge (1 min, 2 mins, 4 mins, 6 mins, 8 mins, 12 mins).
• If a pair of trucks cross the bridge together, they must cross at the speed of the slower vehicle.
• All trucks must use the permit to cross the bridge.
• The bridge closes in 30 minutes.

Control

• Click on the truck's colour to select those you want to cross the bridge.
• Click 'GO!' to send the selected truck/s across the bridge.
• Click 'RESET' to redo the game.
