How does Block Out Level 42 differ from the boss levels?

There are no bosses or devices — it is a pure two-column sorting puzzle. The challenge is separating mixed colors into the correct parallel channels and routing each color to its matching exit at the bottom.

What is the role of the white center blocks in Level 42?

They bridge the two columns and must be removed to allow cross-column swaps. They are swap enablers, not the first blocks to move.

Block Out Level 42 Walkthrough

hard 4 colors

Block Out Level 42 is a two-column sorting puzzle with no bosses or devices. Green, red, white, and black blocks are stacked in two parallel vertical channels separated by a dark center divider, and each color must reach its matching exit at the bottom. The solve works from top to bottom: peel the upper blocks first to create room, shift the white center blocks to enable cross-column swaps, and sort each color to its exit.

Board Notes

Layout: A tall vertical board with two parallel columns of blocks separated by a dark center divider. The left column stacks green, red, white, and black blocks vertically. The right column mirrors this with similar colors. White blocks bridge the center between the two columns. Exits: blue arrow at the top, green and red arrows at the bottom.
Goal: The two columns must be sorted so each color reaches its matching exit at the bottom. The white center blocks are dividers that must be removed to allow cross-column movement. Green blocks need the green exit, red blocks need the red exit.
Opening: Peel blocks from the top of one column first. Then shift the white center blocks to allow cross-column swaps. The solve works strictly top to bottom: clear the upper blocks first to create room for the lower ones to sort.
Danger Zone: Using the center white blocks as an opener leaves the tall outer columns unchanged and the board jammed. The outer columns must thin first before cross-column movement is possible.
Mechanics: Level 42 is a pure two-channel sorting puzzle — the first in Block Out with parallel columns that need cross-sorting. No bosses, no devices, just vertical peeling and color routing.

Quick Tips for Block Out Level 42 (spoiler-free)

Work from top to bottom — the lower blocks cannot sort until the upper ones have cleared their column space.
The white center blocks are swap enablers, not first moves.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Block Out Level 42 — Full Solution

Peel blocks from the top of one outer column to create the first gap.
Mirror the cleanup on the opposite column to keep the board balanced.
Shift the white center blocks to enable cross-column movement.
Sort the red blocks toward the red bottom exit and green blocks toward the green exit.
Continue working from top to bottom, clearing each color layer in turn.
Keep the center divider open for the final cross-column swaps.
Finish with the last blocks once both columns are sorted to their exits.

Colors in this level:

Green, Red, White, Black

Common Mistakes to Avoid

Trying to use the center white blocks before the outer columns have thinned — the cross-column swaps need room that only exists after the top layers are peeled.
Working the bottom blocks before the top is cleared, which jams the columns because there is no vertical room to sort.
