Control Resonant Soda Puzzle: The Soda Machine Code and the Soda Dispenser Tests

Last updated 2026-09-29 · Verified against Five recorded runs across the mart and all three testing facilities · 8 min read

What is the soda puzzle in Control Resonant?

Two puzzles share the name. The Urban Fresh Mart in the West Incursion Zone flashes 3-1-2-1 — the Reversed Drink Order note flips it, so enter 1213 at the register to open the hidden room. The Testing Facility puzzle, in Downtown, the Evacuation Zone and the West Incursion Zone, asks you to transform objects across the yellow lines, place the Soda Dispenser form in every yellow square, and pull the lever.

Two puzzles in Control Resonant share the soda name. They sit in different districts, and they do not share steps or rewards.

  1. Urban Fresh Mart soda machine (West Incursion Zone). A Secret Hideout. The machine flashes 3-1-2-1, the Reversed Drink Order note flips it, and the register takes 1213.
  2. Testing Facility soda dispenser tests in Downtown, the Evacuation Zone and the West Incursion Zone. Unsupervised Science. Carry objects across yellow lines until they take the Soda Dispenser form, set one in every designated yellow square, then pull the lever.

The Urban Fresh Mart soda machine code (1213)

The Urban Fresh Mart is in the West Incursion Zone. Behind the counter, the register shows an ENTER CODE prompt. The code comes from the machine beside it.

How to decode the 3-1-2-1 flashing lights

  1. Watch the Thirst Station machine. Its lights flash 3-1-2-1.
  2. Read the Reversed Drink Order note from Management. The drink order is reversed.
  3. Reverse the flashes. 1213 is the register code.

Where to enter the code and find the hidden room

Use the JASIO register. Enter 1213 at the ENTER CODE prompt. The hidden room opens behind the counter.

How the Testing Facility soda dispenser puzzle works

Three facilities run the same experiment on the Unsupervised Science line. The Shutdown Instructions on the wall require every designated Impermanence area to hold the default Soda Dispenser state. Only then do you operate the lever.

Yellow transformation lines vs. yellow target squares

The floor uses two marks:

  • Yellow lines transform. Carry an object across one and it changes form. Keep crossing until it is a Soda Dispenser.
  • Yellow squares are targets. Put that Soda Dispenser in a square.

How to turn objects into the Soda Dispenser form

  1. Pick up an object and carry it across yellow lines until it is a Soda Dispenser.
  2. Carry it to an empty yellow square. Crossing another yellow line on the way changes the form again.
  3. Fill every designated yellow square in that facility.
  4. Pull the lever.

Testing Facility Reade in Downtown

How to locate the sunken underground entrance

Testing Facility Reade is in Downtown. The entrance is below street level: a lower passage, not the street-facing door. The facility log confirms the shutdown once you are done.

Testing Facility Pearl in the Evacuation Zone

Testing Facility Pearl is in the Evacuation Zone, beside the Survivalist's Bunker. The name wall inside reads TESTING FACILITY PEARL. The floor uses the same lines and squares.

Testing Facility Broadway in the West Incursion Zone

Testing Facility Broadway is in the West Incursion Zone, south of the House of Mirrors and north of the West Supply Route. The entrance is a drainage pipe off the street, and the map marks it once you are close. Use the pipe. The surface marker is not the door.

Why the last object or console is not working

If the lever does nothing, check the room in this order.

Accidental line crossing and form resets

Crossing a yellow line changes the object's form. A dispenser you already made becomes something else if you cross another line while carrying it. Look at what is sitting in each square now.

Confirming every designated square before pulling the lever

Every designated yellow square has to hold a Soda Dispenser. An empty square leaves the shutdown short. Pull the lever last. The Shutdown Instructions put the lever after the placements.

Rewards and Unsupervised Science progress

Health Upgrade Point vs. Power Upgrade Points

The two puzzles do not share a reward.

  • Urban Fresh Mart. The hidden room is a Secret Hideout. Inside is a Health Upgrade Point. Three points raise your maximum health.
  • Testing facilities. Each shutdown advances Unsupervised Science. A Power Upgrade Point sits on the same collect-to-upgrade track as the Health Upgrade Points. One point is not a full Power upgrade.

Secret Hideout and Threshold Researcher trophy progress

The mart's hidden room is one of the six Secret Hideouts — for the full set, see all Secret Hideout locations. For the city's biggest collectible ritual, see The Complete Set.

Threshold Researcher tracks three quest lines: Unsupervised Science, The Last Taxi and Crossing the Threshold. The facilities count toward Unsupervised Science, one of the three.
