How many active slots are available in Level 551?

All five slots are usable from the opening; the pressure comes from repeated charcoal and blue families, not a locked lane.

What should be ignored in the Level 551 picture?

The wooden 1000 counter and hamburger are picture elements. Only numbered colored nests enter the active tray.

Open the diner cat with charcoal 40, blue 36, and lavender 30 families, then hold a lane for the final cyan, white, orange, and charcoal fragments.

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

Fresh-tap the exposed charcoal 40 groups around blue 36, then admit the next charcoal 40 and lavender 30 only after slots release.
Let the opening lanes drain through charcoal 38/32/26/20/15/9/3, the second dark lane 36/30/24/19/13/7/2, and blue 35/33/28/22/16/11/5.
After a lane releases, admit the exposed white, cyan 5, lavender 33, red, yellow, and magenta groups only when their matching picture pixels are reachable.
Stagger the repeated charcoal, purple, blue, orange, and white families instead of preloading all five slots with colors that cannot drain.
Ignore the wooden 1000 counter and wait through the late burger, hair, face, and clothing separation.
Drain the final cyan pair, pale/white fragments, charcoal burger strip, purple accents, and the late orange/charcoal pieces until the frame is empty.

Colors in this level:

Charcoal, Black, Gray, White, Cream, Beige, Orange, Yellow, Red, Blue, Cyan, Teal, Purple, Lavender, Pink, Magenta, Green

Retapping a changing active value such as charcoal 32 or blue 22 as if it were a new nest.
Treating the wooden 1000 picture counter or burger tile as a move budget or nest.

Board notes 5 details

Layout: A purple-haired diner cat in white, green, and magenta clothing sits beneath a hamburger tile; the fixed wooden 1000 counter is picture art.
Goal: Clear the burger, hair, clothing, face, cyan accents, and every isolated late fragment until the frame is empty.
Opening: Fresh-tap the exposed charcoal 40 families around blue 36, then admit the next charcoal 40 and lavender 30 groups as lanes release.
Danger Zone: Active charcoal and blue remainders can fill all five slots while small pink, cyan, white, or lavender features are still buried.
Mechanics: Five usable slots, a fixed in-picture 1000 counter, repeated-color families, and a final cyan/white/charcoal/orange cleanup.
