Why do the four pink stacks open the level?

They attack the broad canopy while leaving one hole available for the first gate release.

Which stacks should be delayed?

Hold yellow 60/80 and duplicate brown 40 cards until the current release has routed.

Open the sleeping cat with pink 24/15/6/8, then reserve one hole through five staggered 500-800 gates and their mystery releases.

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

Start pink 24/15/6/8 and leave the fifth hole open.
Use the first returned pink hole for white 20, then turn the first mystery only after a second pink route is nearly home.
Route the revealed color before brown 40; use brown 18 as the shorter bridge into the counter phase.
Start yellow 60 alone, add orange 40 after brown 18 returns, and keep yellow 80 queued until a slot reopens.
When two counters enter double digits together, stop opening reserve cards and clear both short releases in order.
Turn later mysteries with one empty hole, then alternate the next brown 40 and yellow 80.
Clear the yellow curled body, white tail and face with late yellow, white, orange and brown groups.
Finish the pink canopy, red detail and dark outline, then wait for the last perimeter ants.

Filling the fifth hole with a long stack strands the next mystery or gate release.
Ignoring paired gate endings creates a two-card backlog with no buffer.

Board notes 5 details

Layout: A curled yellow-white sleeping cat rests under a pink background with brown shadows and dark outlines. Five gates begin near 500/600/700/600/800; pink 24/15/6/8 lead white 20, brown 40/18, yellow 60/80, orange 40, red 7 and mystery cards.
Goal: Reduce all five gates, then clear the pink field, yellow curled body, white tail and face, brown shadows and dark outline.
Opening: Tap pink 24/15/6/8 and preserve the fifth hole for white 20 or the first revealed short card.
Danger Zone: Starting yellow 60/80 and both brown 40 groups together leaves no slot when two gates release cards close together.
Mechanics: A fast five-gate animal board cascades 500-800 counters and multiple mystery reveals.
