Why must all five opening cards be green?

The verified solve uses green 35/30/40/30/35 to begin reducing the broad field before the later portrait colors become available.

When is white 60 safe to launch?

Wait until at least two holes have returned after the opening wave so a short chest or portrait card still has room.

Commit the opening five-green wave, then pace white 60, green 50, red 46 and dark 50 while the gnome board's 1000, 100 and 90 gates fall in stages.

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

Fill the holes with green 35/30/40/30/35 and wait until the first five routes return space.
Add green 50, yellow 40 and dark 30, then route white 60 only after two holes are free.
Alternate green 40/50 with red 25/35 while the 1000 counter falls through the 700s.
Continue red 40/46 and green 40/50 as the field counter moves through the 400s, using short yellow cards between waves.
Use peach 8/18/25 and orange 14/30 to clear the inner details as the 100 gate disappears.
Begin reducing the 90 chest with red and yellow routes, keeping room for its short color releases.
Finish the chest with paced green and white cards; keep white 60 separate from dark 50.
Clear the red hat and sled after the chest reaches zero, then remove the white beard and peach face/hands.
Route the remaining dark clothing and yellow ground cards before committing the final green field stacks.
Finish the green star field with the late 20/30/40/45/50 stacks, then wait for the blank-board victory cue.

Sending white 60 as soon as one opening hole returns can block the next short revealed card.
Assuming the 1000 counter is the only gate leaves the inner 100 counter, 90 chest and portrait islands unfinished.

After the five-green opener, wait for two holes before starting white 60.
Use short peach, orange and yellow cards between the longest red, green and dark waves.
Keep white 60 separate from dark 50 during the chest and beard cleanup.

Board notes 5 details

Layout: A red-hatted, white-bearded gnome rides a red-and-yellow sled against a green starry field. Brown counters begin at 1000 and 100, and a central chest begins at 90.
Goal: Reduce all three gates, then clear the green field, red hat and sled, white beard, peach face and hands, dark clothing and yellow ground.
Opening: Tap green 35, green 30, green 40, green 30 and green 35. Wait for that full wave to return holes before adding green 50, yellow 40, dark 30 or white 60.
Danger Zone: The opening occupies all five holes, and later white 60, green 50, red 46 and dark 50 last across gate transitions. Several long routes together can block short chest colors.
Mechanics: A 1000 field counter, 100 inner gate and 90 chest fall sequentially during an extended solve before the gnome and sled fracture into small islands.
