When does the chamber open in Beads Out Level 171?

After the 3-hump wave shell has stepped the chamber from `6` all the way down to `0`, with the left peak feeding `6 -> 5`, the center peak feeding `5 -> 4 -> 3`, the right peak feeding `3 -> 2`, and the yellow-blue-brown U-curve carrying it from `2` to `1` to `0`.

Why is the padlocked dark green box still locked even after the shell is empty in Level 171?

Because the red key labeled `1`, the yellow key, and the pink `?` bottle are tied to the curtain's opening step, and they only become useful once the chamber has reached `0` and revealed the padlocked dark green box at the bottom of the storage.

Beads Out Level 171 Walkthrough

hard 9 colors

Beads Out Level 171 is a 3-hump wave shell (pink-yellow / green-red-blue / blue-red with a yellow-blue-brown U-curve) over a 6-step curtained chamber, a 1x4 cycling target row, a padlocked dark green box, two side keys, and a `?` bottle. Drain the left peak first, walk the center and right peaks next, let the U-curve finish the countdown, and only then spend the keys on the locked box and the bottle.

Board Notes

Layout: The shell is a 3-hump wave: a pink-yellow left peak, a green outer with red and blue inner center peak, a blue-red right peak, and a yellow-blue-brown bottom U-curve with a pink left rail and a red-to-brown right rail. The reserve is a tall storage chamber with a 1x4 target row at the top (green, light green, two empty white), a 3x4 grid of color cubes (green, pink, dark blue / light blue, dark green, gray, purple / red, brown, large red curtained chamber marked `6` with a gold rope / green, dark green padlocked box, light green, yellow, gray, purple), and a bottom-right corner holding a red key labeled `1`, a yellow key, a pink bottle with a `?` mark, and a third small key.
Goal: Step the curtained chamber from `6` down to `0` so it opens and releases the padlocked dark green box, the red and yellow keys, and the pink bottle while the 1x4 target row climbs from 0% to 50% on all four slots.
Opening: Drain the left peak (pink outside, yellow inside) so the chamber steps from `6` to `5`, then clear the center peak (green outside, red and blue inside) to step from `5` to `4` to `3`, then strip the right peak (blue outside, red inside) to step toward `2`.
Danger Zone: The three humps, the bottom U-curve, and the chamber share one continuous tube, so the chamber jumps from `4` to `2` and the 1x4 target row stalls on the wrong color if the right peak drains before the center peak has finished.
Mechanics: Level 171 is a 3-hump wave shell over the highest 6-step curtained chamber in the series so far, paired with a 1x4 cycling target row, a padlocked dark green box, two side keys, and a `?` bottle that only opens once the chamber reaches `0`.

Quick Tips for Beads Out Level 171 (spoiler-free)

The curtain should read `3` or lower by the time the right peak starts draining. If it is still on `4` or higher, the center peak was cleared out of order and you need to redo the center-to-right sequence.
With 9 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
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 Beads Out Level 171 — Full Solution

Drain the left peak (pink outside, yellow inside) into the chamber to step the curtain from `6` to `5` while the 1x4 target row stays at 0%.
Clear the center peak (green outside, red and blue inside) and let the chamber step from `5` to `4` and then to `3` as the first two target slots begin to climb toward 50%.
Strip the right peak (blue outside, red inside) and let the chamber step to `2` while the third and fourth target slots fill toward 50%.
Let the bottom U-curve (yellow on the left, blue in the middle, brown on the right) feed the chamber through `2` to `1` and finally to `0`.
Once the curtain opens, collect the padlocked dark green box, the two side keys, and the pink `?` bottle that were hidden behind it.
Use the red key labeled `1` and the yellow key in that order to unlock the padlocked dark green box and clear the `?` bottle from the bottom-right corner.
Finish by clearing the remaining white, gray, purple, and dark blue cubes from the storage once the chamber has fully opened and the 1x4 target row has reached 50% on all four slots.

Colors in this level:

Pink, Yellow, Green, Red, Blue, Brown, White, Purple, Gray

Common Mistakes to Avoid

Draining the right peak before the center peak has finished, which lets the chamber jump from `4` to `2` and leaves the 1x4 target row stuck on the wrong color while the curtain stalls on `1`.
Spending the red and yellow keys on the small target slots instead of saving them for the padlocked dark green box and the `?` bottle that only appear after the chamber opens.
