Momento: Off Grid Room Puzzle Solutions (The Complete Walkthrough)

This guide provides the complete Momento Off Grid room puzzle solutions, walking you through every step from restoring power to unlocking the final exit. The primary objective is to find three distinct animal masks—the Owl, the Fox, and the Bear—by solving a series of interconnected puzzles, ultimately using them to open the main door and escape the isolated cabin.

Your first step is a thorough sweep of the main room to gather essential tools. Ignore the locked containers for now and focus on the items you can immediately pick up. A systematic search is faster than a frantic one. Success in this room is about sequence; doing things in the wrong order will leave you staring at a puzzle you don't have the tools for yet.

01

The Initial Sweep: What to Collect Firsttag

Before you can tackle the major puzzles, you need to arm yourself with the right tools. Most are in plain sight, but a couple are cleverly hidden. The most crucial item in this initial phase is the Crowbar, as it gates your access to the fuse box and generator fuel.

Here’s your initial collection checklist:

• Crowbar: Found resting against the wooden crates near the fireplace.
• Empty Fuel Canister: On the floor next to the defunct generator in the corner.
• UV Flashlight: On the small bedside table next to the unmade bed. It has no batteries yet.
• Batteries: Inside the top drawer of the bedside table. Combine these with the UV Flashlight immediately.
• Telescope Lens: On the bookshelf, tucked between a few books.
• Diary: A worn leather-bound book sitting on the main table. Read it to get clues about the owner's fascination with constellations, which is a direct hint for the safe puzzle.

Once you have these six items, you're ready to bring the cabin back to life.

02

Powering Up the Cabin: The Generator Puzzletag

Nothing in the cabin works without electricity. The generator is your first major multi-step puzzle, requiring you to find fuel, repair a fuse box, and then start it in the correct sequence. Don't try to flip the main switch until both the fuel and fuses are sorted.

Finding the Fueltag

The fuel is stored in a locked cabinet on the wall. Use the Crowbar you collected to pry the cabinet door open. Inside, you'll find a full Red Fuel Can. Pick it up and combine it with your Empty Fuel Canister to fill it. Now you have a usable fuel source. Take the filled canister to the generator and use it on the fuel intake valve.

Solving the Fuse Boxtag

The fuse box is located on the wall near the generator, its cover held on by four screws. You don't have a screwdriver, but a note tacked next to the box reads, “When you lose the tool, use the coin.” Check the small bowl on the fireplace mantel to find an Old Coin. Use this coin on each of the four screws to open the panel.

Inside, you'll see a diagram and four colored fuses lying at the bottom of the box: Red (15A), Blue (20A), Yellow (5A), and Green (30A). The diagram shows which amperage is required for each of the four circuits. The solution is to place the fuses in the correct slots according to their amperage:

• Slot 1 (Lights): Yellow (5A)
• Slot 2 (Auxiliary): Red (15A)
• Slot 3 (Locks): Blue (20A)
• Slot 4 (Main): Green (30A)

Activating the Generatortag

With fuel in the tank and the fuses correctly placed, you can now start the generator. Interact with the control panel. There's a three-step startup sequence. Press the buttons in this order: 1. Prime Fuel, 2. Engage Choke, 3. Ignition. The generator will roar to life, and the cabin lights will flicker on. You've now unlocked the ability to solve the electronic puzzles.

03

Unlocking the Safe: The Constellation Codetag

With the power on, you can now focus on the large, imposing safe in the corner of the room. The code is tied to the cabin owner's astronomical hobby, hinted at in the diary. This puzzle involves the telescope, a star chart on the wall, and the diary itself.

First, go to the telescope by the window. It's missing a lens. Place the Telescope Lens you found earlier into the eyepiece. Now you can look through it. When you do, you'll see the night sky, but it's the star chart on the opposite wall that provides the context. The chart displays four specific constellations: Leo, Orion, Ursa Major, and Cassiopeia. The diary mentions that the owner's “four guardians” watch over his secrets.

Point the telescope to align with the position of each of the four constellations on the chart. As you focus on the correct star cluster for each, a symbol will glow brightly in the eyepiece. Note down these four symbols. Now, refer back to the Diary. The last page has a cipher that translates these specific astronomical symbols into numbers.

• The symbol for Leo corresponds to 8.
• The symbol for Orion corresponds to 5.
• The symbol for Ursa Major corresponds to 2.
• The symbol for Cassiopeia corresponds to 1.

The order is determined by the order they appear on the star chart, from left to right. Therefore, the safe combination is 8-5-2-1. Enter this code into the safe's keypad. The heavy door will swing open, revealing the Owl Mask.

The Three Masks: Locations and Solutionstag

With the Owl Mask in hand, you have one of the three keys to your escape. The other two, the Fox Mask and the Bear Mask, are hidden behind their own unique puzzles that are now fully accessible.

The Owl Masktag

As detailed above, the Owl Mask is your reward for solving the constellation puzzle and opening the safe. It’s the most straightforward of the three, requiring you to connect clues from the diary, star chart, and telescope. Once you have it, place it in the corresponding slot on the main exit door to track your progress.

The Fox Masktag

The Fox Mask is hidden in a secret compartment revealed by using your UV Flashlight. On the wall section to the right of the bookshelf, there's a patch of wallpaper that looks slightly discolored. Shine the UV Flashlight on this area.

A set of hidden symbols and arrows will appear, glowing in the ultraviolet light. The symbols depict a sequence of movements: Up, Up, Left, Down, Right, Down. This is the solution for the directional lock on the wooden chest at the foot of the bed. Go to the chest and input that exact sequence. You'll hear a click, and a false bottom inside the chest will pop open. The Fox Mask is nestled inside.

The Bear Masktag

The final mask, the Bear Mask, is the most complex to acquire. It's located at the bottom of the old water well outside, which you can only see through the main window. You can't reach it by hand. You'll need to use the magnetic fishing game set up on a small table.

First, you need the Magnetic Hook, which is locked inside a small puzzle box on the fireplace mantel. The box has four sliders with animal carvings: a fish, a rabbit, a bird, and a deer. A nearby carving on the wall shows the food chain: “The deer eats the grass, the rabbit eats the carrot, the bird eats the worm, the fish eats the fly.” The solution is to arrange the sliders based on the animals' typical elevation: Bird (highest), Deer, Rabbit, Fish (lowest). The box will open, giving you the Magnetic Hook.

Attach the hook to the Miniature Crane on the table. Now, you can play the fishing game. The goal is to navigate the magnetic hook through a simple maze to retrieve the Bear Mask from the miniature well in the game set. It's a test of steady hands. Once you successfully lift the mask from the game, the real prize appears. A compartment on the side of the table slides open, revealing the actual, life-sized Bear Mask.

05

The Final Escape: The Exit Door Puzzletag

With the Owl, Fox, and Bear masks in your possession, return to the main exit door. Place each mask into its corresponding stone carving slot. The Owl Mask goes in the top slot, the Fox Mask in the left, and the Bear Mask in the right.

Placing the final mask doesn't immediately open the door. Instead, it activates a final puzzle. The eyes of the three masks will glow, and the circular stone in the center of the door will reveal three rotating rings with different symbols. A riddle appears etched above the door: “The wise one sees the path, the cunning one follows the tracks, the strong one stands its ground.”

This riddle tells you the correct alignment:

1. Outer Ring (Owl): Rotate it to the symbol of a Path/Road.
2. Middle Ring (Fox): Rotate it to the symbol of Paw Prints.
3. Inner Ring (Bear): Rotate it to the symbol of a Mountain.

Once all three rings are aligned correctly, the stone mechanism will retract. You'll hear a deep thud as the locks disengage. The door is now unlocked. Push it open and step outside to complete the Off Grid room.

Frequently Asked Questionstag

What is the safe code in Momento Off Grid? The safe code is 8-5-2-1. It's found by using the telescope to view four constellations from the wall chart (Leo, Orion, Ursa Major, Cassiopeia) and then translating the resulting symbols using the cipher in the diary.

Where is the last mask in the Off Grid room? The last mask is typically the Bear Mask or the Fox Mask. The Fox Mask is in a secret compartment in the chest, opened with a code found using the UV flashlight. The Bear Mask is the reward for solving the magnetic fishing crane game after getting the hook from the animal slider puzzle box.

How do I use the UV flashlight in Momento? First, find the flashlight on the bedside table and the batteries in the drawer. Combine them in your inventory. To use it, select the flashlight and shine it on the discolored wallpaper next to the bookshelf to reveal a hidden directional code for the chest.

Is there a time limit in the Off Grid room? No, there is no time limit in the Momento Off Grid room. You can take as much time as you need to explore, read the clues, and solve the puzzles without any pressure.
