The solution for Rapid Router Level 48 requires a general algorithm that uses conditional "if" statements and sensor blocks to navigate the van. Unlike earlier levels where you could hard-code moves, Level 48 penalizes non-general solutions that don't account for path variability. Verified Solution (Blockly)
A formally verified solution documents the exact tile type, orientation, and grid coordinates for each step; a verification log shows the connectivity and constraint checks passed.
repeat until block
Test and Refine: Press the Play button. If the van hits a dead end or misses a house, check that your if statements are checking for roads in the correct order of priority. Scoring and Efficiency
Default Action: If there are no red lights and no turns available, move forward. Else: move forward. Verified Code Structure (Blockly) Repeat until 🏠 (at house) If 🚦 (traffic light is red) 🛑 Stop Else if ⬅️ (can turn left) ↩️ Turn left Else if ➡️ (can turn right) ↪️ Turn right Else 🚚 Move forward
