Pizzeria Weekly Case: Puzzle Routes and Fingerprint Verdict

Follow the Pizzeria weekly case through the pattern or tomato route, find the remaining evidence, and choose the suspect named by your own fridge fingerprint.

Choose your branch, then verify the print

Match the dining-room grid or blend four tomatoes to obtain the kitchen Lockpick. Finish the kitchen branch, collect the remaining clues and vote for the name on the fridge fingerprint reader. Diary numbers and suspects vary.

Follow the branch present in your round

Use either the pattern route or blender route, then collect evidence and read the fridge print.

    §Identify the puzzle branch before searching#

    Look around the dining room before trying a remembered code. The reviewed runs show a wall grid with a matching pattern clue, or a blender with rotten tomatoes. Follow the objects present in your round. The kitchen door requires a Lockpick in both recorded branches.

    Weekly cases are announced as replayable. Check the case selection in your current lobby; an announcement window does not establish when a case disappears.

  2. Pattern route: open the kitchen, then read the diary

    Pattern route: open the kitchen, then read the diary

    Success check
    The kitchen keypad accepts the current diary number.
    If it remains unclear
    Read the detailed checks below and compare the current clue before retrying.

    §Pattern route: open the kitchen, then read the diary#

    Copy the highlighted squares from the hanging flag clue onto the dining-room wall grid. The nearby box opens and contains a Lockpick. Take it, use it on the kitchen door and complete three timing-bar stages.

    In the kitchen, check the trash bin beside the shelves for another Lockpick. Use it on the white lockbox and open the Diary inside. Copy the number after "Kilometers driven this week" into the kitchen wall keypad.

    The first recorded diary shows 3831; the next run uses 7068. These are examples of changing clues. Use your own diary. A missed lockpick stage is followed by a new attempt in the footage, so complete all three stages before leaving the door or box.

  3. Blender route: make juice in each room

    Blender route: make juice in each room

    Success check

    §Blender route: make juice in each room#

    Collect four rotten tomatoes in the dining room and place all four in its blender. Collect the resulting acidic juice and use it on the locked box. Take the Lockpick inside and open the kitchen door with the three-stage timing game.

    The kitchen has its own tomatoes and blender in the reviewed third run. Collect four more tomatoes, make a second batch and apply it to the kitchen box. Read the pattern revealed inside, then reproduce it on the kitchen wall grid.

    If the grid refuses a click, adjust your camera angle until the intended square can be selected. Compare every selected square with the current pattern. The recorded player corrects a misplaced square before the puzzle-complete notice appears.

  4. Puzzles complete, investigation still blocked

    Success check
    The phone permits ending the investigation.
    If it remains unclear
    Read the detailed checks below and compare the current clue before retrying.

    §Puzzles complete, investigation still blocked#

    Use UV at the wall near the kitchen doorway for the hidden text. With the Magnifying Glass equipped, sweep the kitchen floor, the fridge reader, the table, the sink counter and the cash-register counter. The reviewed runs include two finds at the register.

    Inspect each revealed clue until the case file updates. The recorded run has seven clues, including the wall text and fridge fingerprint. If the phone still blocks ending the investigation, compare your missing entries and revisit these surfaces with the appropriate tool. Completing the locks alone leaves the evidence stage unfinished.

  5. Read the fridge fingerprint before ending

    Read the fridge fingerprint before ending

    Success check
    The verdict confirms the suspect identified by the print.
    If it remains unclear
    Read the detailed checks below and compare the current clue before retrying.

    Read the supporting evidence

    §Read the fridge fingerprint before ending#

    Inspect the fingerprint reader beside the walk-in fridge and read the full name it identifies. The first two recorded runs name Lucy (Cashier); the third run identifies Sofia. The name changes, so use the identification shown in your round.

    Once the investigation is ready to end, equip the phone, choose END INVESTIGATION and use VOTE SUSPECT for the person identified by that fridge print. Check the verdict confirmation. If you have not read the print, use RESUME INVESTIGATION when available and inspect it before voting.

    Keep these weekly-case checks separate from the older story-case answer table. A suspect named in an archived Bakery or Motel walkthrough supplies no answer for Pizzeria.
