Are red 125, 119, 106, 94, 72, and 32 separate nests?

No. They are visible active remainders along the same long red route; a fresh nest appears only after a lane releases a new card.

What is the completion check for Level 724?

Wait until the board is blank and every tray is empty. The closing interstitial comes after that empty frame.

Open the red-orange mask through its long red and magenta remainders, then preserve access for the late green, dark, yellow, and pale fragments.

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

Start orange 58, the visible yellow group, and gray/purple 42, using the two open lanes for the first released cards.
Let those active groups drain, then follow fresh black 85, pink 20, red, and yellow groups as they appear in released lanes.
Stay with the long red remainder as it falls through 125, 119, 106, 94, 72, and 32; do not replay those counts as separate red nests.
Keep magenta 20 and 12 in their active context while using new lanes for the green eyes, black outline, white/pale pixels, and yellow side details.
Follow the late red, magenta, pale, black, orange, and yellow groups through the shrinking face, waiting whenever a tray is still occupied.
Clear the final tiny dark, orange, yellow, white, and pale fragments, then wait for all five trays and the board to become empty.

Colors in this level:

Red, Orange, Pink, Magenta, Yellow, Green, Black, White, Gray, Purple, Pale

Treating each changing red remainder as a new red nest and filling the board with duplicate red clicks.
Loading repeated pink/magenta groups before the green, black, white, or yellow mask details are exposed.
Stopping at the recognizable-face stage while a small outline or pale fragment still occupies a tray.

Use the two initially open lanes, but wait for the orange, yellow, and gray/purple groups to release before committing to the next card.
Read red 125/119/106/94/72/32 and magenta 20/12 as active remainders, not as new nests.
Keep a lane for the late green, black, white, orange, yellow, and pale fragments around the shrinking mask.

Board notes 5 details

Layout: A red-orange cat/fox-like mask with green eyes, yellow side details, a purple top, and a dark outline fills the board. The opening has orange 58, a yellow group, gray/purple 42, and two empty lanes. Fresh front rows include black 85, pink 20, red 33, and yellow 15.
Goal: Clear the outer orange/yellow/gray frame, the large red face band, the magenta/pink center, green eye accents, and the final black, white, orange, yellow, and pale outline fragments.
Opening: Start orange 58, yellow, and gray/purple 42, then take released black, pink, red, and yellow cards. The long red active remainder visibly falls through 125, 119, 106, 94, 72, and 32 while magenta 20 and 12 remain in the route.
Danger Zone: Long red and magenta remainders occupy lanes while the mask is still broad. Filling every vacancy with another pink/red group can block the green, black, white, and yellow pixels exposed around the eyes and lower edge.
Mechanics: The red 125-to-32 and magenta 20/12 values are active tray remainders, not fresh nests. A fresh nest is the new card exposed after a lane releases; completion requires an empty board and empty trays.
