Level 78 opens with pink 10 and blue 20 in the first two slots, then alternates long purple/blue frame lanes with a warm orange/yellow/red finish.

If the player asks you to sign in, open the video on YouTube instead.

Park pink 10 in slot 1 and blue 20 in slot 2, then start the first purple and yellow releases through the two empty slots.
Cycle purple 40, purple 40, and yellow 20 only after the pink and blue counts fall so the row does not lock.
Use red 10 and red 20 for the warm center, returning to blue and purple as the mirrored outer lanes open.
Let orange and yellow clear the remaining center bars while slot 5 stays free; use the late orange 10, yellow 30, orange 10, red 10 checkpoint.
Finish the last red and warm fragments, drain the remaining blue/purple lane, and wait for the complete reward state.

Colors in this level:

Purple, Blue, Pink, Orange, Yellow, Red

Entering both long purple buses before the first pink/blue departures release slots.
Filling slot 5 with a second blue bus while the warm center still needs orange and yellow.
Stopping when one side of the mirrored frame clears even though the opposite cool lane remains.

Use the two empty slots behind pink 10 and blue 20 before committing to both purple 40 buses.
Wait for a cool-color departure before parking another long blue or purple bus.
Keep the fifth slot open for the late orange 10, yellow 30, orange 10, red 10 row.

Board notes 5 details

Layout: A mirrored geometric badge or frame uses purple, blue, pink, orange, yellow, and red pixel lanes. The opening queue shows purple 40, purple 40, and yellow 20, with red 10, red 20, and blue 20 lower in the chain; the first settled tray has pink 10 in slot 1 and blue 20 in slot 2.
Goal: Open the warm center, then preserve room for the long purple and blue frame lanes. Finish only after the red, yellow, pink, cool-color, and final warm fragments have drained from the mirrored frame.
Opening: Park pink 10 in slot 1 and blue 20 in slot 2, then use purple 40, purple 40, and yellow 20 only as a matching bus is close to release. Add red 10, red 20, and blue 20 as the inner badge lanes open.
Danger Zone: The early full row reads pink 4, blue 6, purple 15, yellow 5, and blue 19. Later, keep slot 5 open while the tray cycles orange 10, yellow 30, orange 10, and red 10 so the remaining cool lane can depart.
Mechanics: The badge collapses in mirrored warm and cool waves. Its apparent symmetry does not remove the five-slot constraint; departures determine whether the long purple and blue streams can finish.
