Sixteen Centimillion Bits is a Version 3.0 side quest in Wuthering Waves. You must first enroll as an official Startorch Academy student during Chapter 3 Act 1, What Burns Beneath Frostlands. Songdis starts the quest near the Startorch Academy arcade by Spacetrek Archives, then sends you to Bjartr Woods in Roya Frostlands. Complete the Hopshroom and Soundstep pattern games, replay the note sequence in reverse for a missable chest, and finish the final three-round Hopshroom test.
The minigames award three Basic Supply Chests and one Tidal Supply Chest. The listed quest rewards are 200 Union Experience, 20 Astrite, two Advanced Resonance Potions, two Advanced Sealed Tubes, 20,000 Shell Credits, and five Soliseeds of Essehalo. Afterward, wait two in-game days—or advance the in-game clock—to receive the Sixteen Centimillion Bits music track from Songdis.
How do you unlock Sixteen Centimillion Bits?
The quest is unavailable at the beginning of the game. Game8’s quest guide says you must become an official Startorch Academy student during Chapter 3 Act 1, What Burns Beneath Frostlands. Once that story requirement is met, the side quest appears in Soliseed Plains, Lahai-Roi.
- Complete the Startorch Academy enrollment requirement in Chapter 3 Act 1.
- Travel to the arcade area near Spacetrek Archives in Startorch Academy.
- Speak with Songdis. She asks you to meet her at Bjartr Woods.
- Open the quest log and follow the active marker to the woods. The available walkthroughs do not publish coordinate values, so the marker is the reliable way to set the route.
Nerdschalk places the opening at the Spacetrek Arcade and describes the destination as Bjartr Woods in Roya Frostlands. The quest’s listing uses Soliseed Plains and Lahai-Roi, so those names can appear in different map or quest-log contexts.
Where does the quest take place?
There are two practical locations to remember:
- Start point: Songdis, at the arcade close to Spacetrek Archives in Startorch Academy.
- Challenge area: Bjartr Woods in Roya Frostlands, reached by following the quest marker.
An interactive-map search result was marked as updated September 30, 2026, but its displayed excerpt does not expose marker coordinates. Use the live in-game marker rather than relying on an unverified coordinate copied from another page.
How do you clear the Hopshroom pattern imitation?
The first activity is a visual memory test. A Soliskin demonstrates a jump pattern on the Hopshrooms, and you must reproduce that pattern on the same platform sequence.
Watch the demonstration
Let the Soliskin finish its example before moving. The safe approach is to note the order from left to right, or assign each Hopshroom a quick number in your head. Nerdschalk describes the pattern as being shown in two runs, giving you another chance to confirm the order.
Repeat the jumps
Jump on the Hopshrooms in the demonstrated order. A mistake means you should concentrate on the next demonstration instead of trying to improvise. Completing this activity is associated with a Basic Supply Chest.
How does the Soundstep note sequence work?
The second activity changes from platform movement to a ranged note sequence. Follow the Soliskin’s musical notes in order by aiming at the targets with an appropriate ranged option.
Choose a ranged method
Game8 lists an aiming gun-wielding Resonator such as Chixia or Aalto, or the Hoverdroid Shooter utility. Nerdschalk also describes using the Hoverdroid for this sequence. The important requirement is accurate ranged aiming, not a particular combat build.
Copy every note in order
Watch the complete sequence, then shoot the notes in the same order. Keep the reticle steady and avoid firing early; the activity is checking sequence accuracy rather than damage. Finishing the normal Soundstep sequence awards another Basic Supply Chest.
How do you get the missable reverse-sequence chest?
Before leaving the Soundstep area or advancing the objective, replay the second challenge in reverse order. This is an optional objective and the easiest reward to overlook.
- Finish the normal note sequence.
- Remain at the challenge instead of moving on.
- Start the sequence again and enter the notes from the final note back to the first.
- Complete the reverse pattern to receive the extra Basic Supply Chest.
Game8 explicitly warns that this reversal is easy to miss. Nerdschalk also describes reversing the pattern. If you leave without doing it, the quest’s listed chest total will be short by one Basic Supply Chest.
How do you finish the final Hopshroom rounds?
The last activity returns to Hopshrooms but expands the test to three rounds. In each round, the Soliskin demonstrates a pattern, and you jump on the Hopshrooms opposite the demonstrated pattern.
Read the pattern before moving
Watch the full demonstration in every round. Treat each round as a separate sequence; do not assume the previous order carries over. The “opposite” instruction means you must reproduce the demonstrated arrangement on the opposite side or orientation indicated by the activity, not simply repeat a remembered route without checking the current display.
Complete all three rounds
Follow the platform prompts for each of the three demonstrations. Completing the final round completes the side quest and awards a Tidal Supply Chest, according to Game8’s walkthrough.
What are the minigame rewards?
The challenge rewards are split between the ordinary activities, the optional reverse sequence, and the final test.
| Activity | Reward | Why it matters |
|---|---|---|
| Hopshroom pattern imitation | Basic Supply Chest | First platform-pattern activity |
| Soundstep note sequence | Basic Supply Chest | Use a ranged Resonator or Hoverdroid Shooter |
| Soundstep sequence in reverse | Basic Supply Chest | Optional and easy to miss |
| Final three-round Hopshroom test | Tidal Supply Chest | Completes the side quest |
That produces three Basic Supply Chests and one Tidal Supply Chest in total. The reverse sequence is why the number of chests is higher than the number of principal activities.
What are the complete Sixteen Centimillion Bits rewards?
Game8’s guide, last updated December 26, 2025, lists the following completion rewards:
| Reward | Quantity | When you receive it |
|---|---|---|
| Union Experience | 200 | Quest completion |
| Astrite | 20 | Quest completion |
| Advanced Resonance Potion | 2 | Quest completion |
| Advanced Sealed Tube | 2 | Quest completion |
| Shell Credit | 20,000 | Quest completion |
| Soliseeds of Essehalo | 5 | Quest completion |
| Basic Supply Chest | 3 | Earned across the two pattern activities and the reverse sequence |
| Tidal Supply Chest | 1 | Earned from the final Hopshroom rounds |
| Sixteen Centimillion Bits music track | 1 | Songdis’s delayed follow-up |
Game8’s all-quests index independently lists the core resource quantities and places the quest in Soliseed Plains. Its music guide lists the Sixteen Centimillion Bits track as unlocked by completing this side quest.
When does Songdis send the music follow-up?
The music reward does not arrive immediately when the minigames end. Wait two in-game days after completing the quest. Both Game8 and Nerdschalk describe advancing the in-game clock by 48 hours as an option instead of waiting through real-world time.
- Finish the quest and confirm that the completion rewards have been issued.
- Advance the in-game clock by two days, or let two in-game days pass naturally.
- Check for Songdis’s automatic message.
- Meet Songdis when prompted and complete the conversation to collect the track.
Nerdschalk describes the same 48-hour timing followed by a conversation. The clock-adjustment method is an in-game convenience described by the guides; it is not a separate quest objective.
What should you do if one Soliskin or chest seems to be missing?
First check the Soundstep location. The optional reverse sequence is counted separately from the normal note challenge, so completing the ordinary sequence does not automatically award its chest. Return to the second activity and enter the notes backward before proceeding.
If the missing item is the final chest, verify that all three final Hopshroom rounds were completed. The final Tidal Supply Chest is tied to finishing that sequence, while the earlier platform and note activities account for the three Basic Supply Chests.
Because published guides do not provide exact map coordinates, use the active quest marker and the current quest log to confirm that you are at the correct Bjartr Woods objective. Patch changes can also alter labels or marker placement, so the in-game objective text should take priority over an old screenshot.
Is the trophy name “Bits Tengoku” universal?
Nerdschalk refers to a trophy as “Bits Tengoku,” but the available material does not establish that this wording is identical across every language or platform localization. If the name does not appear exactly that way in your client, check the in-game trophy or achievement list for the entry linked to the quest rather than assuming the reward is missing.
Can you replay the minigames after finishing the quest?
The cited walkthroughs explain how to clear the activities and collect their chests, but they do not establish a post-completion replay rule. Do not count on being able to repeat a challenge for additional rewards; complete the reverse Soundstep sequence before advancing so the optional chest is secured during the quest.
Frequently Asked Questions
How many chests should Sixteen Centimillion Bits give in total?
The guide total is four chests: three Basic Supply Chests and one Tidal Supply Chest. The third Basic chest comes from replaying the Soundstep sequence backward, not from a separate map pickup.
Do I need Chixia or Aalto to finish the note game?
No specific character is mandatory in the guide descriptions. An aiming gun-wielding Resonator such as Chixia or Aalto is one option, while the Hoverdroid Shooter utility is another.
Can I wait two real-world days for Songdis’s song?
The timing is measured in in-game days. You can let the game clock advance naturally, or use the in-game clock to move forward by 48 hours as described by the walkthroughs.
Why can’t I find exact coordinates for Bjartr Woods?
The published walkthrough material identifies the region and landmark but does not provide coordinate values. Start from Songdis near Spacetrek Archives and follow the active quest marker for the current route.
Is the “Bits Tengoku” trophy name the same in every version?
That name comes from a secondary guide and may reflect a particular localization. Check your own client’s trophy or achievement list if the wording differs.
