Block Out Level 23 Walkthrough

hard 6 colors

Block Out Level 23 is a knot board with two framed lower boxes marked `11` and `8`. Use the top blue lane and right yellow gate to untie the curled center path, then let the two boss boxes fall once the knot is gone.

Board Notes

Layout: Two framed lower boxes marked `11` and `8` sit under a curled middle path made of red, blue, and purple pieces. A blue top exit and a yellow right gate serve the upper chamber, with tall yellow and red bars across the roof.
Goal: Open the curled middle path so the lower framed pair finally has room to shrink.
Opening: Use the top blue route and the right yellow gate first. The lower `11` and `8` values are still locked while the center path is curled shut.
Danger Zone: Focusing on one lower box before the center knot is open leaves the other one stranded.
Mechanics: Level 23 is a knot-and-boss puzzle where both lower frames depend on the same middle path.

Quick Tips for Block Out Level 23 (spoiler-free)

Untie the center before attacking the lower boxes.
The top blue route is part of the opener, not the closer.
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 23 — Full Solution

Feed the top blue route first so the middle curl has one less blocker.
Use the right yellow lane to pull the upper yellow column away from the knot.
Rotate the red and purple curl pieces until the central path is no longer closed.
Start shrinking the framed `11` box once the left half of the knot has opened.
Let the framed `8` box fall after the right half has also cleared.
Clean up the tall red and yellow columns that were holding the curl in place.
Finish with the last blue top route after both lower frames are nearly gone.

Common Mistakes to Avoid
