How to Solve Block Out Level 420 — Full Solution

  1. Send the exposed right green group through its gate, then clear reachable red/green pieces beside it.
  2. Remove ordinary upper yellow/blue rows and left cyan/green groups to expose the framed horizontal slots.
  3. Route the framed yellow/red rows and yellow-framed cyan square only after matching edge lanes open.
  4. Clear red blocks around the horizontal center mechanism, leaving the bridge between the U's legs empty.
  5. Move upper blue/cyan bars outward, then take the framed purple/orange vertical piece down the opened left side.
  6. Reduce the lower-left orange-framed 3 device while clearing adjacent blue/cyan groups through floor and side gates.
  7. Free the two lower-right framed columns, then remove remaining long cyan/blue rows without covering the right gate.
  8. Clear the late purple/orange columns from the left leg, slide the now-unblocked red symbol bar through the red side gate, and drop the final orange column through the left floor exit.

Common Mistakes to Avoid

  • Moving a framed block before a straight route exists from its full footprint to the matching gate.

Board notes 5 details
Layout
A dense U holds blue/cyan/green/yellow/red/purple/orange bars, framed horizontal and vertical pieces, a yellow-framed cyan square, a red center mechanism, and a lower-left device marked 3.
Goal
Open straight routes for each framed piece, clear the orange-framed 3 device, move the red symbol bar through its side gate, and empty both legs without blocking their shared bridge.
Opening
Take the exposed right green group, clear center-right red/green blocks, then peel ordinary yellow/blue rows away from the upper framed slots.
Danger Zone
A long blue/cyan row or framed purple/orange column beside the red center mechanism blocks transfers between the U's two legs.
Mechanics
Several slotted/framed blocks share the board with a state-changing red horizontal mechanism and an orange-framed three-count device.

Frequently Asked Questions

  • What is the safest opening in Block Out Level 420?

    Start with the exposed right green exit, then remove ordinary red, green, yellow, and blue groups before touching the framed pieces.

  • Why do the lower framed columns get stuck?

    They depend on the central bridge and right-side lane. Keep both clear until the upper blue/cyan rows and red mechanism no longer block them.
