Route Reference
Key opening, middle, and finish positions for this route.

Side Shelves Above A Long Lower Bend
Level 78 has five short shelves on the upper-left, four on the upper-right, one shelf below the center, and four garages along the bottom. A road snakes between the banks before making a long empty lower bend.
Recommended flow:
upper-left blue -> upper-right green -> upper-left yellow -> upper-right blue -> upper-left white -> upper-right red -> lower-center blue -> dark shelf blockers -> cyan bottom-left -> pink bottom -> purple bottom -> orange bottom-right
Alternate shelf batches so both banks shrink together. The lower bend is a buffer, not a place to park unfinished colors.
Clear the center blue shelf only after the upper banks have stopped feeding the vertical section. Remove the remaining dark blockers, then open the four bottom garages from left to right.
If one side becomes much taller, complete its exposed shelf before continuing on the shorter side. If purple or orange cannot turn, cyan or pink remains on the long bottom road.
Saving The Lower Bend
Alternate blue/green, yellow/blue, and white/red across the two upper banks. Let the vertical section clear between pairs; the long lower bend should stay unused during this part.
Blue from the center shelf is the transition. Finish it, remove the dark blockers, and inspect the whole lower curve before opening cyan. Pink follows, then purple and orange.
If one bank remains taller, clear its highest exposed shelf rather than draining the shorter side. If purple or orange stalls, finish cyan or pink already travelling along the bottom. The bend is useful only while it remains empty enough for one complete color batch.
Level 78 is controlled by the empty bend below the shelves. Keep it clear during the upper phase and it provides enough room for the four garage batches to finish cleanly.
The upper wall pairs should finish above the vertical drop: blue/green first, yellow/blue second, and white/red third. If a car passes into the lower bend during this phase, complete its shelf before switching banks.
The center blue shelf is a deliberate handoff. Once it and the dark fronts clear, cyan may use the long bottom route. Pink follows, then purple; orange is last on the lower-right. Check the bend after each garage. A car waiting there belongs to the active color and should be parked before the next lower cover opens.
If the upper banks are uneven when blue becomes exposed, finish the taller bank first. Blue should mark the end of all shelf traffic, not overlap the last red or white row. That pause preserves the lower curve for cyan's full batch.
Cyan should clear the lower-left approach completely before pink begins, and pink should do the same before purple and orange use the far end of the bend.
