What does the 1000 number mean?

It is the globe's remaining-pixel countdown; the actual ant-nest counts are shown in the active tray and queue.

Which region clears last?

The board contracts to a small upper-right blue ocean and green land cap before isolated blue pixels finish.

Food Hunt: Pixel Puzzle level guide

hard 7 colors

Break the charcoal rim around a 1000-pixel Earth, alternate blue oceans with green continents, and finish the shrinking upper-right ocean cap.

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

Start white 1 and charcoal 13, then select blue 38, green 30, and teal 71 for the rim and first exposed globe regions.
Continue through blue 36, green 5, teal 69, then blue 32, charcoal 15, blue 25, and teal 69 without crowding the tray with land colors.
As the left half collapses, use blue 20, blue 9, teal 68, followed by blue 8, purple-gray 6, and teal 68; wait for active remnants to release slots.
Refill with blue 42, green 38, blue 42, teal 68, then blue 23, green 2, blue 28, green 22, and teal 53.
Clear the upper cap through blue 10, purple-gray 7, blue 16, white 5, teal 49; then green 9, green 20, blue 42, white 9, and teal 9.
Preserve outline room through charcoal 3, blue 39, cyan 9, charcoal 45, charcoal 43, then the purple-gray, blue, white, and teal reductions around the final ocean patch.
Finish with the small blue, green, white, teal, and charcoal nests observed near blue 4, blue 7, blue 2, and white 4 until the counter reaches zero.

Blue, Green, Teal, Cyan, White, Charcoal, Purple

Loading several green nests while the blue ocean and charcoal rim remain can block the front row.
Treating the central countdown as an ant-nest count confuses board progress with tray state.

Board notes 5 details

Layout: A circular Earth uses blue oceans, green continents, white clouds and polar highlights, teal accents, and a thick charcoal rim around a central 1000 counter.
Goal: Open the dark circular shell, clear the blue-green globe in stages, and remove the last isolated blue ocean pixels when the counter reaches zero.
Opening: The observed opening uses white 1 and charcoal 13, then blue 38, green 30, and teal 71; later reductions show blue 36, green 5, teal 69, blue 32, charcoal 15, and blue 25.
Danger Zone: Green land nests can occupy the tray while the charcoal rim, white cloud pixels, and broad blue ocean still need entry space.
Mechanics: A visible 1000 counter falls as a circular shell collapses from the left side toward a small upper-right blue-green cap.
