Rapid Router is a free, online educational game designed to teach core coding concepts to children aged 5 to 14. Created by Ocado Technology, the game simulates a delivery van navigating a city map to deliver groceries. It starts with simple Blockly puzzles and gradually progresses to text‑based Python programming. With over 109 levels, students learn everything from basic sequencing to advanced loops and conditional statements.
Heuristics for construction:
In Level 48, your delivery truck must navigate a complex grid with multiple destination points and changing traffic lights. Standard linear instructions will fail because the route requires dynamic decision-making based on the truck's immediate surroundings. Key Objectives Navigate the truck to all required delivery zones. Avoid driving into buildings or off the road. Use the fewest blocks possible to achieve a perfect score. Verified Solution Code (Python)
After countless failed attempts, stack overflows, and vans driving into virtual ditches, the has been isolated, tested, and documented. Watch this walkthrough to see how these blocks

Before coding, write down the movement commands in simple English. For example:
