Which group starts the U-shaped ramp on Level 685?

The first cyan group, already at 45 in the opening frame. Follow its 45-then-22 remainder across the ramp edge before touching other colors.

What survives after the broad ramp collapses?

The purple rider and a small dark/cyan rail at the upper right. Their groups need reserved capacity while the large cyan/blue ramp drains.

Start the first cyan group and let its visible 45 then 22 remainder work through the U-shaped ramp edge.
Add pale/gray, then blue and red as their regions expose; read the later 42/12/12/68/60 row as active state, not five fresh taps.
Use orange and brown groups on the lower curved ground while continuing cyan/blue groups on the U-shaped ramp.
All five trays start occupied, and the large ramp colors drain at different rates.
Follow the teal 11, brown 27, red 17, and purple 38 checkpoint without treating those remainders as new nests.
Let the final red 2, purple 1, orange 1, then pale, magenta, dark, and blue tail groups empty the remaining rider and rail pixels.
Confirm the empty frame and every active tray blank before leaving the level.

All five trays start occupied, and the large ramp colors drain at different rates.
Spending the first released lane on a buried purple or orange group before the dark/blue rider colors become reachable.
Treating the cyan 42 and later teal/brown/red/purple checkpoint values as fresh taps instead of active remainders.

Start the first cyan group and follow its visible 45 then 22 remainder across the ramp edge.
Refilling the first vacancy with a buried purple or orange group can block the dark/blue rider color that becomes exposed next.
Do not spend the first empty lane automatically—the rider and upper rail expose after the broad ramp, so their dark, purple, and cyan groups need reserved capacity.

Board notes 5 details

Layout: The picture is a purple-clad rider above a large cyan U-shaped skate ramp, with orange/red curved ground, gray side pillars, and a small dark/cyan rail at the upper right. A picture counter starts near 1500. Five trays start empty after the intro. The first selected cyan group is already down to 45 in the first clear frame; pale/gray and later blue/red groups join as the ramp exposes. The cyan 42,
Goal: Remove the cyan ramp and orange/red ground, then clear the purple rider, blue clothing, dark outlines, gray pillars, and small right-side rail. The rider and rail persist after the broad ramp collapses.
Opening: Start the first cyan group and follow its visible 45 then 22 remainder across the ramp edge. Add pale/gray groups next, then blue and red only as the upper field and curved ground expose. Treat the later cyan 42, pale 12/12, blue 68, red 60, and teal/brown/red/purple rows as active checkpoints rather than new simultaneous taps.
Danger Zone: All five trays start occupied, and the large ramp colors drain at different rates. Refilling the first vacancy with a buried purple or orange group can block the dark/blue rider color that becomes exposed next.
Mechanics: This is a high-count ramp-to-rider transition. Cyan/blue dominates early, orange/red clears the lower curve, and the final phase isolates the purple rider plus a dark/cyan rail.
