Why split red 40 and white 40 into separate waves?

Each route occupies a hole for a long time; running both together leaves no buffer for the short green leaf and pink facial stacks.

When do mystery stacks reveal?

Mystery cards open mid-run as the pink field shrinks, introducing green 14 and short pink stacks that need an empty hole.

Clear the tomato face by opening pink 28 and dark 25, separating red 40 from white 40, and saving room for the green leaf and small pink details.

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

Tap pink 28 and dark 25, then wait for the first stream to move.
Route red 40 through a returned hole; do not add white 40 at the same time.
Use short pink 2/8/11 and dark 11/20 as handoffs between the two long routes.
Send white 40 only after red 40 has returned, then add white 27/29.
Route green 10/13/14 as the leaf area opens, keeping one buffer free.
Clear red 26/31/37 and white 40 face fragments as the shell thins.
Finish the remaining dark outline, green leaf and pink details, then wait for Victory.

Starting red 40 and white 40 together blocks the tray before green and pink details can enter.
Ignoring mystery-stack reveals lets newly exposed cards pile up without a free hole.

Board notes 5 details

Layout: A red tomato or apple face with a green leaf, white inner face, dark outline and small pink features sits on a pale-pink field. Five holes serve pink 28, dark 20/25, red 40, white 40 and mystery stacks that reveal green 14 and short pink cards later.
Goal: Clear the pale-pink field first, then remove the red fruit shell, white face, dark outline, green leaf and the remaining pink facial details.
Opening: Tap pink 28 and dark 25, then wait for a hole to return before sending red 40 or white 40.
Danger Zone: Red 40 and white 40 together consume two holes for a long time. If dark 20 or a mystery reveal enters while both are active, no space remains for the short green and pink stacks.
Mechanics: A two-color face surrounded by a broad pink field, with mystery-stack reveals that introduce green and extra pink cards mid-run.
