Square Parking Block
The central square is the whole problem in Level 152. Pink and yellow stacks sit above it, gray/white rows fill the square, and green/blue columns wait below. If you pull the bottom first, the square has nowhere to drain.
Start with the pink top stacks to open the upper entrance. Then clear yellow from the top. With the entrance open, work through the gray and white cars inside the square. This is the part to do patiently; avoid sending unrelated bottom cars into the ring while the square is still full.
After the central rows shrink, move the green bottom columns, then the blue bottom columns. Close the level with the remaining purple or pink lower cars that become exposed after the bottom clears.
Use this sequence:
pink top stacks -> yellow top stacks -> gray/white central square -> green bottom columns -> blue bottom columns -> purple/pink lower cars
The visual check is simple: before starting bottom green, the central square should look noticeably emptier than it does in the opening frame.
