Block Out Level 173 Walkthrough
Block Out Level 173 is a circular two-stage board split by a wide orange-framed horizontal barrier marked 27. Drain the upper side lanes to release that barrier, immediately free the cyan center square, and only then move the lower yellow and red shapes across the midpoint.

How to Solve Block Out Level 173 — Full Solution
- Clear the exposed red and green pieces from the side gates.
- Remove the left cyan cluster and top purple strip to widen the upper chamber.
- Route the central yellow and green column outward after both side lanes open.
- Finish the remaining upper blue and red pieces until the marked 27 barrier releases.
- Clear the cyan center square before moving the lower yellow and red shapes across the midpoint.
- Send the lower purple and blue pieces to their side gates.
- Remove the final yellow bottom piece and remaining corner blocks for the win.
Colors in this level:
Purple, Cyan, Yellow, Green, Red, Blue, Orange
Common Mistakes to Avoid
- Leaving the cyan center square occupied after the 27 barrier opens.
- Collapsing the yellow-green column before both side lanes can accept its pieces.
Quick Tips for Block Out Level 173 (quick clues)
- After the barrier opens, clear the cyan center square first—yellow and red shapes need that midpoint free.
- Do not leave barrier-edge scraps while tall pieces try to cross the former 27-line; they turn the open gap into a choke.
Board notes 5 details
- Layout
- Rounded board split by a wide orange-framed horizontal block marked 27. Above it: purple on the roof, cyan at left-center, a tall yellow-green middle column, and red-green pieces on the right. Red and purple gates sit on the sides; cyan and blue gates sit lower down.
- Goal
- Clear the upper color field to reduce and release the marked 27 barrier, free the center crossing, then drain the lower half that appears beneath the barrier.
- Opening
- Remove the exposed side red and green pieces, open the cyan-left and purple-top lanes, and clear the yellow-green center column only after both sides have room.
- Danger Zone
- When the marked block releases, upper remnants and the lower field share the same center. Leaving the cyan square there prevents the lower yellow and red shapes from crossing.
- Mechanics
- A 27 horizontal barrier divides a circular board into sequential upper and lower stages that share one midpoint square.
Frequently Asked Questions
What does the orange-framed 27 barrier actually do?
It splits the circular board into two stages. Until it opens, lower and upper traffic cannot share a midpoint safely.
Why is the cyan center square mandatory after the open?
Lower yellow and red shapes pivot on that cell. Occupying it with leftovers freezes both post-barrier routes.
