Level 565 opens two one-count chambers before a left 9-counter, feeding nested blue-lime and red-green framed L pieces around a fixed central spine.

Clear exposed orange, yellow, cyan, and blue starter blocks through the left and bottom exits, shifting the red-cyan L away from the fixed cyan cells.
Open the lower-right 1-chamber and take its first blue-lime framed L through the bottom green gate before moving the next nested L.
Open the upper-right 1-chamber and clear its long yellow/pink bars and large red-green framed L without covering the central wall lanes.
From the upper-right reveal, send the long yellow bar toward the upper-left yellow gate, clear the exposed pink blocks through the right pink gate and the purple horizontal through the right purple gate, then drain blue and green blocks through the left/bottom lanes until the upper-left 9-counter opens.
Clear the left chamber's yellow bar, pink/red shapes, purple stair, and second red-green L before returning to the lower framed pieces.
Send the upper green hook through the top gate, then clear the right green hook and lower green L through the bottom gate one at a time.
Route the outlined blue step and outlined blue L through the right blue gate, followed by the long blue center bar.
Clear the remaining large blue L from the left field, then send the final small blue square through the right blue gate.

Colors in this level:

Orange, Yellow, Cyan, Blue, Green, Lime, Red, Pink, Purple

Pulling two nested blue-lime L pieces into the lower-right turn at once and locking both against the central spine.
Parking a long blue block across the cyan outline cells and cutting off the last green route.

Exit each blue-lime framed L through the bottom green gate before releasing the next nested piece.
Keep both sides of the central purple wall open for the final blue and green wave.

Board notes 5 details

Layout: A large left chamber marked 9 sits beside purple and orange chambers marked 1. The starter pocket contains a red-cyan L, mixed small blocks, a framed cyan-green bar, and fixed cyan outline cells split by a purple wall.
Goal: Open both one-count chambers, clear the left 9-chamber, and feed every framed L through the narrow lanes around the fixed center spine.
Opening: Sort exposed orange, yellow, cyan, and blue blocks through the left/bottom gates while moving the red-cyan outlined L away from the cyan outline column.
Danger Zone: Only one framed blue-lime L can turn through the lower-right junction at a time; a long blue bar across the central outline cells also strands the late green pieces.
Mechanics: Two one-count chamber reveals lead into a slower 9-counter, with multiple double-color framed L pieces and persistent center-wall/outline-cell fixtures.
