Relay teal, green, charcoal, and orange through the horse picture, then wait for the final orange pixel.

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

Treat active teal 42 and charcoal 24 as already-in-flight opening remainders; do not start a second teal 42 from the changing tray value.
As lanes release, use fresh teal 40, green 55, charcoal 20, and teal 42/46 for the border, field, and outline colors.
Stagger orange 65/60, green 55/45/40/50, teal 44, and blue/cyan 40 so a short lavender, cream, white, or brown group can enter.
Let active blue 40, green 17, charcoal 2, then blue 40, green 20, and orange 57 drain; these are remainders, not extra source taps.
Admit lavender 16, green 27, cyan 32, and cream 22 to strip the rider, saddle, and HORSE lettering; ignore the fixed 70 art marker.
Let the late white 7, brown 3, orange 15, cream 13, and charcoal 30 state resolve, then wait through blue 15, brown 8, orange 7, and charcoal 11.
Leave the last lane for the single orange pixel around 260 seconds and accept completion only after the frame and active row are empty.

Layout: An orange horse and rider sit inside a green border and cyan field with a blue saddle, charcoal/cream outlines, a purple question-mark patch, and HORSE lettering; the white 70 is fixed picture art.
Goal: Remove the border, horse, rider, saddle, lettering, and isolated outline fragments until the landscape frame is empty.
Opening: Five slots are open; active teal 42 and charcoal 24 are opening remainders, while the fresh queue shows teal 40, green 55, charcoal 20, teal 42, green 44, teal 46, blue 40, and green 50.
Danger Zone: Orange 65/60, green 55/45/40/50, teal 42/44/46, and blue/cyan 40 families compete with short lavender, cream, white, brown, and charcoal groups.
Mechanics: A five-slot landscape relay recorded at 1440x1080 strips the horse in layers; active 7/3/15/13/30 becomes a sparse blue/brown/orange/charcoal tail ending on one orange pixel.
