How to Solve Block Out Level 423 — Full Solution
- Remove the top-right red and yellow groups, then take the neighboring cyan and blue pieces through their edge gates.
- Clear the upper green and purple rows until the 5-count shutter retracts and exposes the middle pocket.
- Take the middle cyan horizontal bar, then remove the orange marked column, red row, and small yellow groups.
- Continue with the middle green, cyan, and purple pieces as the 11-count shutter drops through 7, 4, and 1.
- Open the lower reservoir and clear its outside red, purple, yellow, and green rows first.
- Route the long upper red and green rows out before they stop across the left-center bridge.
- Remove the ordinary lower cyan bars and green L-groups while preserving the floor-green gate.
- Send the outlined cyan vertical pieces through the left/lower cyan routes one at a time.
- Clear the remaining green hook and floor bar, leaving the outlined purple hook alone at top-left.
- Sweep the purple hook across the empty board and through the lower-right purple gate for completion.

Common Mistakes to Avoid
- Using the left-center bridge as a parking spot and sealing the only route around the right-side notch.
- Sending the purple hook toward its gate while ordinary lower bars still occupy the center and floor.
Quick Tips for Block Out Level 423 (quick clues)
- Treat the left-center opening as a bridge, not storage, whenever a new layer is about to open.
- Leave the purple connected hook until ordinary lower bars and the cyan verticals are gone.
Board notes 5 details
- Layout
- A packed top chamber sits above purple shutters marked 5 and 11 in a board with a large middle-right notch. Left, right, and floor gates serve purple, green, cyan, blue, yellow, and red groups across three reveal layers.
- Goal
- Open the upper shutter, use the middle pocket to reduce the lower shutter, then clear the bottom reservoir and route the connected cyan bars plus purple hook before the 1:50 timer expires.
- Opening
- Take the top-right red and yellow pieces, then clear reachable cyan, blue, green, and purple groups until the 5-count panel retracts.
- Danger Zone
- A long red row or outlined cyan vertical across the left-center bridge blocks the floor-green route and prevents the final purple hook from crossing the notched board.
- Mechanics
- Sequential 5- and 11-count shutters create three layers, while a right-side notch and outlined connected pieces narrow the usable transfer lane.
Frequently Asked Questions
Which shutter opens first in Block Out Level 423?
Open the upper panel marked 5 with the top chamber; its middle reveal then supplies the clears that reduce the lower panel marked 11.
Why should the purple hooked piece be last?
Its full connected outline must cross the board around the large right-side notch, which is safest only after the cyan verticals and floor groups leave.
