Why should the left boss fall first in Block Out Level 34?

The left boss has a `10` counter versus the right's `20`. Collapsing the smaller tower first creates the room the larger tower needs to drain. If you split effort equally, neither boss makes enough progress.

What are the hidden colored blocks in Level 34?

Green, yellow, and blue blocks are hidden inside the two boss chambers. They only appear after a boss counter drops below `9`, adding a second phase of color sorting to the late game.

Block Out Level 34 Walkthrough

expert 6 colors

Block Out Level 34 is labeled 'Hard Level' and features a twin-boss layout with a left `10` boss and a right `20` boss sitting above a shared red-white-black basement. The solve runs in three phases: clear the basement to bring down both counters, collapse the smaller left tower first to create room, then use that space to accelerate the right tower's collapse. Once the bosses fall below `9`, hidden colored blocks — green, yellow, blue — spill out and need their own sorting.

Board Notes

Layout: Two tall blue chambers sit side by side, each wrapped in an orange frame. The left chamber shows a boss counter of `10` and the right shows `20`. Top-edge counters read `12`, `20`, and `20`. Below both chambers, a shared basement is packed with red, white, and black blocks. A small green `5` block and a blue `10` block sit at the bottom corners. Exit arrows point left, right, and downward.
Goal: The basement is the real opener. Every cleared basement piece reduces the boss counters above. The left `10` boss is smaller and should collapse first, creating room for the right `20` boss to start draining. The late game reveals green, yellow, and blue blocks hidden inside the chambers — they only appear after the boss counters drop below `9` (visible at 00:57 in the video).
Opening: Start by working the right side of the basement: slide the white blocks toward the right exit and move the black blocks out through the bottom. The green `5` block at the bottom-left corner is an early move that opens a lane for the left chamber. The blue `10` block at the bottom-right stays longer because it supports the right chamber. The left `10` boss starts visibly collapsing (counter drops through `7`) once the basement is about half-cleared.
Danger Zone: Splitting effort equally between both chambers stalls both. The right `20` boss needs double the basement space to drain. If neither boss reaches the critical threshold, the basement fills back up with revealed blocks that have nowhere to go. The left tower must fall first to create the room the right tower needs.
Mechanics: Level 34 is the first twin-boss room in Block Out where the counters differ this much — `10` versus `20`. The lopsided counts force a strict order: small boss first, large boss second. The revealed blocks that spill from the collapsing chambers add a second phase of sorting that earlier boss rooms did not have.

Quick Tips for Block Out Level 34 (spoiler-free)

The left `10` boss is your progress meter. If it is still above `5` when the right boss reads `17`, the basement needs more left-side focus.
Watch for the phase transition around counter `9` — that is when hidden colored blocks start spilling out of the chambers.
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 34 — Full Solution

Slide the white blocks in the right basement toward the right exit and move the black blocks out through the bottom arrow.
Use the green `5` block at the bottom-left as an early move to open a lane under the left chamber.
Continue thinning the basement until the left `10` boss counter visibly starts dropping — watch for `7` on the left counter.
Focus remaining basement work on the left side so the `10` boss collapses fully before the right `20` boss drops below `17`.
Once the left chamber empties, use the freed space to accelerate the right `20` boss reduction.
As the right boss falls below `9`, colored blocks — green, yellow, blue — spill out. Sort them through the side and bottom exits.
Finish with the last red basement pieces and the remaining revealed colors after both chambers are empty.

Common Mistakes to Avoid

Splitting effort equally between both bosses from the start — the `20` boss needs so much more room that neither tower reaches the critical threshold, and revealed blocks pile up with nowhere to go.
Ignoring the green `5` block at the bottom-left corner as an early move, which delays opening the lane under the left chamber where progress matters most.
