What is the safe opening for the 161 counter?

Use pale-white 12, yellow 2 and dark-purple 23 first, then add red 26/25/30 as those short routes return.

Why save the yellow 1/2 cards?

The low 36-to-14 stages need short matching routes to expose the face and brown gate block without competing with another long red stack.

Lower the 161-step brown counter with pale-white 12, yellow 2 and dark-purple 23, then pace the red-shirt portrait through its gate-block cleanup.

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

Tap pale-white 12, then yellow 2 and dark-purple 23 as the first holes return.
Route red 26, red 25 and red 30 one at a time while the counter drops from 161.
Hold red 36/30 and dark-purple 35 until a matching hole is free.
Use pale-white 35/34 and red 30 as the counter passes 129 and 108.
Clear the red shirt and lower outline before opening another long red route.
At 101 and 90, use dark-purple 23/32/25 and pale-white 11/25/34 returns.
Let the counter reach 58 and 36 before spending the remaining red 35/30 stacks around the face.
Route yellow 1/2, pale-white 3/8/12 and dark-purple 4/5 as the brown block shrinks.
Finish the dark hair, pale face, red fragments and the final brown gate block.
Wait for every perimeter ant to leave and confirm the Colony Flow clear cue.

Colors in this level:

Pale white, Yellow, Dark purple, Red, Brown, Gray, Pink

Opening red 36/30 and dark-purple 35 before the short white/yellow routes return fills the tray above the 100 counter stage.
Stopping when the red-shirt portrait disappears leaves the dark hair, pale face and brown gate block in the endgame.

Board notes 5 details

Layout: A dark-haired character in a red shirt with gray/dark lower clothing sits beside a brown gate block. The counter descends through 161, 129, 108, 101, 90, 58, 36 and 14. Opening stacks show pale-white 12, yellow 2, dark-purple 23, red 26, red 25, red 30, red 36 and red 30.
Goal: Lower the brown counter, clear the red shirt and dark hair, then remove the pale face, dark outline and final brown gate block.
Opening: Use pale-white 12, yellow 2 and dark-purple 23 first, then red 26/25/30 as holes return. Save red 36/30 and dark-purple 35 for the first counter transition.
Danger Zone: Red 36/30 and dark-purple 35 are long routes while the counter is above 100. Taking them together hides yellow 2 and pale-white returns that expose the face and brown gate block.
Mechanics: A high brown counter advances through frequent checkpoints. The target changes from a full red-shirt portrait to face, hair and a detached brown block, with a separate low-counter cleanup.
