Parcel Circuit
Program two parcel routes through one shared sorting belt. Tap ordinary belts to rotate clockwise. The center sorter flips between left and right AFTER each parcel leaves it. Red must visit the red stamp and red exit; Blue needs the blue stamp and blue exit. Launch delay holds Blue at its inlet for 0–3 ticks, preventing both parcels from entering the shared lane together. Start locks the program; Step advances both parcels simultaneously. A collision, loop, wrong stamp/exit or missing belt loses. Watch the visible tick trace, then restart to refine the program.
