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.

Quick tips

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

Step-by-step solution

Step-by-step solution

  1. 1

    Move 1

    Peel blocks from the top of one outer column to create the first gap.

  2. 2

    Move 2

    Mirror the cleanup on the opposite column to keep the board balanced.

  3. 3

    Move 3

    Shift the white center blocks to enable cross-column movement.

  4. 4

    Move 4

    Sort the red blocks toward the red bottom exit and green blocks toward the green exit.

  5. 5

    Move 5

    Continue working from top to bottom, clearing each color layer in turn.

  6. 6

    Move 6

    Keep the center divider open for the final cross-column swaps.

  7. 7

    Move 7

    Finish with the last blocks once both columns are sorted to their exits.

Common failure points

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.
