For a missing Momento puzzle, open Room Puzzles and check which objects its hint selects. The room references below explain the required placements, object states, hidden pieces, and book sets. Some props appear only after a golden-box choice, so a room can look unpacked while a puzzle’s objects are still unavailable.
Start with your current room, then use the achievement table for cleanup. The early-room sections include the Realities layouts, with separate instructions where an item or required surface moves. This is a reference for the puzzle groups listed below, not a guarantee that every puzzle added in later updates is covered.
Find the missing puzzle before restarting a life
- Unpack the boxes currently available. When a golden box is locked, follow its glowing vine to the clue object and inspect that clue. Return to the box, choose a memento, and unpack the props that appear afterward.
- Open Room Puzzles with the puzzle-piece icon. Select an unfinished entry and use its Hint button to identify its objects and, where shown, the surfaces they need. If the required props have not appeared, make the golden-box choice that supplies them.
- After the placement or interaction, check that the entry has a tick. Moving a cube, radio, mug, or instrument can leave its state unchanged; use right-click when the solution calls for it.
- For a room you have already visited, enter Wall of Memories from the main menu. Its hover card separates Puzzles Found, Momentos Chosen, and Level Complete. Pick the room with the missing puzzle or choice, finish through the star, and compare its card afterward.
A Wall replay ends by returning to the Wall. It can fill gaps in that room, but choosing a different memento there will not take you through a new sequence of downstream rooms. Reach unvisited rooms in Story Mode. Realities supplies three Cot layouts, two layouts for each childhood room, and two for each teenage room; those totals include the originals. The Wall’s variant arrows let you select a layout you have already visited; encounter a locked variant in Story Mode first.
Choose a room, then solve its puzzles
The Cot plush selects the next childhood bedroom: dinosaur, teddy, or unicorn. Later, the majority of your three childhood mementos selects the teenage room; two choices for the same destination are enough. The next three choices use the same majority rule for the adult room. Your final branching adult-room item selects the ending room.
| Childhood starting room | Teenage room to reach | Choose these two mementos |
|---|---|---|
| Dinosaur or Unicorn | Mum’s Place | Ms. Googly Eyes (the potted plant) + dollhouse |
| Teddy or Unicorn | Dad’s Place | Knight figure + soccer ball |
| Dinosaur or Teddy | Tyler and James’s Place | Ant farm + solar system mobile |
The plush does not lock your final career. Use the Momento route guide for the later choice pairs and all six ending-room entrances. Keep this page open for the objects and puzzle conditions once you arrive.
Cot Room: shared objects and plush-specific props
Complete the shared checks with the starting objects, then unpack the props belonging to your chosen plush. Collect the other plush sets on later visits. The tables group actions by object, so one row can contain more than one puzzle.
| Object group | Placement or interaction | Detail that can block completion |
|---|---|---|
| Cube and blocks | Right-click the Rubik’s cube until solved. Build a tower using numbered blocks 1 through 6 in ascending or descending order. Also make a stack of any three blocks. | The three-block stack and six-block tower are separate checks. |
| Drawings and mug | Hang every child drawing. Right-click the mug until it is steaming. | A placed mug still needs its state changed. |
| Reading nook | Put Hello Baby!, Baby Built a Rocketship!, Teddy Saves the Day!, and I Want to See the Stars in or on the nook. | All four books belong to this set. |
| Train and xylophone | Adjust the train pieces so all three connect. Put the small metal stick with the xylophone. | The stick is in a train car in layout 1, the crayon box in layout 2, or the mug in layout 3. |
| Crayon box | Return the four loose crayons to their box, leaving six crayons in total. | The crayons already inside the box count toward the total. |
| Couch reading corner | Put the round and square pillows on the couch, switch the lamp on, and put one of the three story books on the side table or chair. | Use Teddy Saves the Day!, Baby Built a Rocketship!, or I Want to See the Stars. |
| Sticky note | Remove the sticky note from I Want to See the Stars and right-click it to crumple it. | Removing the note alone leaves the interaction unfinished. |
| Dinosaur props | Set the three animal figures and four fences around the barn, with at least one animal inside. Straighten the tile puzzle. Put the cow in the train car marked with a sun. | The barn, tile puzzle, and cow-in-train placement are separate checks. |
| Teddy props | Put all three sports balls in the basket and gather the three toy planes. For Goldilocks, pair Papa Bear with the large red bed, Mama Bear with the medium yellow bed, and Goldilocks with the small blue bed; stand Baby Bear beside the blue bed. | Keep the beds near one another. Match each figure to its own bed. |
| Unicorn props | Stand all three vegetables upright in their pots, scribble on the drawing board, and fold the yellow blanket before putting the purple doll on it. | Change the blanket and board states before checking their entries. |
Dinosaur Bedroom: books, containers, and toy sets
| Puzzle group | What to do |
|---|---|
| Postcards and birthday | Gather Dad’s seven postcards. Read the return-to-sender note, open its box, and read the birthday card inside. |
| Space toys and plushies | Put the small astronaut and rocket on the moon coaster. Place the dinosaur, koala, and Polly together on the bed. Solve the cube. |
| Beach and Polly | Put the shovel and rake in the bucket beside the beach ball. Place Polly in the glass jar for its separate check. |
| Backpack | Pack the walkie-talkie, Polly, glue bottle, and cow toy. A completed Polly-in-jar check lets you reuse Polly for this placement. |
| Rocket bookcase | Shelve at least 12 of its 15 eligible books. Exclude Shape Languages and All the Wonderful Things; use the book puzzle hint to identify the rest. |
| School papers | Throw away the pink detention slip. Put the yellow prize ribbon on the framed I Want You to See the Stars drawing. |
| Dinosaur set | Place all four dinosaur figures on the toy set, then add the dinosaur plush for the companion check. Put the shark plush in or on the nightstand. |
| Dollhouse | Put the chicken and all four white fences on the lawn. Seat the purple figure on the stool that appears in front of the vanity. |
| Ant farm | Use the magnifier directly in front of the farm. The butterfly jar belongs on the windowsill. |
| Plants and decals | Attach the blue and pink flower decals and the large leaf decal to the window. Put all three plant cuttings and Ms. Googly Eyes on the windowsill. |
| Larger astronaut and mobile | Find the astronaut in a whiteboard basket and place it beside its rocket. Put a marble in its hand. Set the moon lamp on the nightstand and gather the eight glow-in-the-dark stars around it: four small and four large. |
Teddy Bedroom: ocean toys and the castle cushion
| Puzzle group | What to do |
|---|---|
| Starting objects | Reconnect the train cars. Put Dad’s six letters on the map, Teddy on the skateboard, and the two shark rainboots together. Fill the empty jar with the flowers. |
| Ant-farm props | Put the butterfly jar on the windowsill and the shark plush on the ocean play mat. |
| Soccer set | Gather the photo of Sam’s first live game, soccer ball, and trophy. |
| Space-mobile props | Cluster all ten wall stars on the leftmost wall: five large and five small. Place the solar system mobile near its two planet decals, the large astronaut beside the spaceship, and a marble on the leftmost mobile string. |
| Airplane props | Set the boat lamp on the ocean mat and the handheld telescope on the windowsill. Hide the pink detention slip in the red-and-yellow truck’s scoop. |
| Dinosaur props | Set all four dinosaurs on the toy island, then put the island on the ocean mat. |
| Knight and castle | Use the puzzle hint to select nine castle pieces and three knight figures, then move all 12 onto the cushion. Use the left cushion in layout 1 or the right cushion in layout 2. For the separate sword check, put the toy sword in Teddy’s hand; the teddy bear plush is the target. |
Unicorn Bedroom: spread the books across five surfaces
The book puzzle needs at least 12 of 14 eligible books distributed across at least five eligible surfaces. Filling one bookcase with the whole set will leave the surface condition unmet. First choose five surfaces from the matching layout below, put a qualifying book on each, then distribute the remaining books until at least 12 are placed.
| Eligible group | Books to use |
|---|---|
| School books and notebooks: 5 | All three school textbooks (yellow maths-symbol cover, blue science cover, red ABC cover), plus the art and English notebooks. |
| Dinosaur books: 2 | Jurassic Times Volume 1 and Volume 2. |
| Art books: 2 | See That Tree? You Can Paint it! Environment Art 101; Shape Languages and How to Shape Them. |
| Other books: 5 | Teddy Saves the Day!; Dragon Man: Re-Birth; EN TUNE – Keep in Sync; 60,000 Miles Deep; Knock Ons: 99 Knock Knock Jokes. |
| Layout | Eligible surfaces |
|---|---|
| 1: window nook and door cubes | The bookcase below the window; inside or on the white nook below the window; each of the two shelves above the bed; each of the two cube shelves above the door; the desk top or its raised shelf. |
| 2: mirror nook and bedside cubes | Use the bedside cube shelves, the wall-mounted bed shelf, the mirror nook, its overhead shelf, the doorway bookcase, or the desk. |
The backpack check uses a smaller set: pack at least three of Learning Mathematics Year 5, Essential Sciences, the art notebook, and the English notebook. Finish the surface puzzle first if you need to use those same books in both checks, and watch for the tick before moving them.
| Remaining puzzle group | What to do |
|---|---|
| Postcards, beach toys, and flowers | Attach Dad’s eight postcards to the grid board. Stand the bucket beside the beach ball and store the shovel and rake inside it. Put two flowers in the vase. |
| Cube and marbles | Solve the cube and put the marbles into a glass jar. Three marbles can finish the check before later props are unpacked; the pink one is on the moon coaster in the bedside nook. |
| Pairs and plushies | Pair the roller skates and rainboots. Gather the purple, unicorn, and koala plushies on the bed. |
| Paper cleanup | Throw away the childhood scribbles and at least four paper scraps or crumpled sheets. |
| Straighten wall hangings | Layout 1 uses the 4A seating chart, James and Sally and me, I Want You to See the Stars, and Sally’s first painting. The painting can already be discarded after Spring Clean. Layout 2 needs I Want You to See the Stars straightened. |
| Plant and soccer props | Put Ms. Googly Eyes on the windowsill, the three collectible cards in their display, and the purple plush inside the trophy. |
| Sketchpad props | Return all six crayons to their box. |
| Dollhouse | Stack the main room below the attic, attach the outer wall on the right, and add three stools, a vanity, bedside table, dining table, bed, couch, porch swing, flowery fence, and three figures. One stool is above the door and another is at the left corner of the desk. For the separate plush check, put the unicorn, purple plush, and dollhouse table in its main room. |
| Knight and castle props | Gather all six knights beside the dragon. Move at least 28 of the 31 castle/knight pieces onto the bed platform; use the hint to find pieces that are still outside the set. |
Teenage rooms: Dad, Mum, and Tyler and James
Golden-box alternatives supply different prop sets in these rooms. If a microscope, press, camera, or gramophone is absent, collect the matching choice on another visit. The shelf change in Mum’s room is also worth checking before moving the whole set.
Dad’s Place
Put the two wooden figures on the boat. Return Terry to the habitat, then use the open laptop keyboard for the separate Terry check. Store four shirts, cleats, and the yellow beanie in the cabinet. Empty the food basket and gather five Polaroids. Display the NUMBER 11 BILLY CARMINE poster on the main wall. Interact with the phone and boombox. Group The Alliance of the Chain, The Two Trees, and The Queen Restored; pair From Troy to Tokugawa with Advanced for Highschool: Grammar and Composition.
Microscope: put the petri dish on its tray, shut the skeleton in the cabinet, and group three research papers, notepad, and pen on the bed or desk. Chess: place every piece on the board. Gramophone: open Passion Extreme, turn it horizontal, and place it on the player. Drinking bird: lower its head; put the binoculars on the far windowsill.
Mum’s Place

Pair the brimmed hat with the uniform jacket and gather the three star-light strings.
Complete the chess board, camera with attachment on its tripod, three sketches on the easel, and seven cards in their display. Open the flower press, add the full poppy, then close it. Turn a vinyl record sideways, then set it on the record player.
Tyler and James’s Place
Shelve three T-shirts, sweatshirt, scarf, cleats, and bag. Use the tall bookcase for From Strum to Strut, You Are What You Eat!, Advanced for Highschool: Grammar and Composition, Advanced Mathematics 2, Plums of Fury, Check or be Checked, and Music from the Musical Fortitude. Display Mr. School Captain and Tyler, put three darts on the board, assemble the telescope, empty the three-item white basket, and play the saxophone, ukulele, harmonica, metronome, and amp. Attach the stand with Soar Me Through The Sky, solve the cube, and discard six blue/white notes.
Press the yellow wattle flower, place the petri dish on the microscope, and group four medical diagrams. Put two yellow flowers in or beside the vase, discard the drawing on the wooden board, and return two loose charcoal sticks to the tray (four total). Lower the drinking bird, pair it with the small bird figure, and fill the yellow bottle. Put five pictures and three hanging photos on the same wall.
Adult rooms: interactions that are easy to leave unfinished
Doctor’s Loft
Move the three sheets covering The Coldest Happy Pair in Svalbard! The crumpled sheet above the ladder also needs to be opened. Empty the sink (one cup, two plates) and bed box. Read Medicine Class of 2017, Family Zoo Trip, and Flight of the Jailbird. Stand Intercosmic, Roman Soldier, Sean’s Redemption, and Unnatural in or near the console table.

Pair each shoe type and set the telescope on the desk tripod.
Solve the cube, use the phone and TV, and right-click all seven dice; one is in a mug. Discard both ramen cups. Open the gift box below the TV and interact with the robo-dog. Read the fine notice before throwing it away.
Off-The-Grid
Bring the dog from outside, beside the telescope tripod, to its bed near the fireplace. Set the adjusted birdbath beside the birdhouse, gather five flowers in the vase, and assemble the telescope. Discard the Pinter & Co Legal envelope and letter, red note signed J, and Tyler’s funeral pamphlet. Hang the world map on the door wall, gather five gems with the seashell, discard the cleats, and hang the crutch on the wall to the right of the map.
Fill one dog bowl with food and one with water. Use the phone before discarding it, change the walkie-talkie state, and play the door chimes. Light the fireplace, four candles, lantern, and six wall lights. The kitchen set has its own checklist below.
Off-The-Grid kitchen inventory
The hint for this puzzle identifies both eligible items and storage surfaces. Include the dark-blue serving bowl that starts out holding fruit; leaving that bowl out can leave the kitchen unfinished.
| Group | Items to put away |
|---|---|
| Cups and containers | Three food-storage containers, four mugs, four coloured cups, two small yellow containers, cookie container, pink candy bag, noodle cup, white box, and brown coffee bag. |
| Bowls and plates | Three red-rimmed bowls, two yellow-rimmed bowls, two large yellow-rimmed plates, two large blue-rimmed plates, one medium plate, one small plate, and three large dark-blue serving bowls. |

Coach formations: count ten magnets from left to right
Use all ten dot magnets for each formation. Count the left, middle, and right columns separately; spacing within a column is flexible. Move the magnets to the next formation after its puzzle entry has ticked.
| Formation | Left column | Middle column | Right column | Total |
|---|---|---|---|---|
| 4-4-2 | 4 | 4 | 2 | 10 |
| 4-5-1 (Control the Centre – 451) | 4 | 5 | 1 | 10 |
| 4-3-3 | 4 | 3 | 3 | 10 |
| 3-4-3 | 3 | 4 | 3 | 10 |
Greenhouse potion recipes
Right-click each ingredient before putting it into the cauldron. Check the resulting puzzle entry after each pair. The rose-and-strawberry recipe needs an unpacked plant, so leave it until that item is available.
| Recipe | First ingredient | Second ingredient |
|---|---|---|
| 1 | Rosemary | Orange |
| 2 | Rosehip | Dried plant with the palest, longest leaves |
| 3 | White dried plant | Purple dried plant |
| 4 | Mint | Dried plant with slightly wavy leaves |
| 5 | Rose | Strawberry plant |
If a new potion fails to record after the correct ingredients, a reported workaround is to make one, reset the room, and make the next on another visit. Use that only when the entry will not tick; a reset is not a required step between recipes that register normally.
Achievement cleanup by room
Momento lists 24 Steam achievements. Six ending-room achievements reward finishing those routes; their paired puzzle achievements require the optional room puzzles too. For First Steps, clear the Cot puzzle entries across the choices you need. One visit supplies only the props from that visit’s choices; collect the other plush sets on later visits.

|---|---|
| First Steps | Cot Room |
| Meteoric | Dinosaur Bedroom |
| Going for Gold | Teddy Bedroom |
| Limitless Imagination | Unicorn Bedroom |
| Father’s Favourite | Dad’s Place |
| Live, Laugh, Love | Mum’s Place |
| Third Wheeling | Tyler and James’s Place |
| The Grind | Doctor’s Loft |

| Greenhouse | She’s A Witch | Fire Burn, And Cauldron Bubble |
| Rural Rescue | Man’s Best Friends | Crazy Creature Couple |
| Space Station | Beam Me Up, Sammy | All Systems Go |
Love, Tyler is the all-levels completion target. Unlock unvisited rooms in Story Mode before checking it. The Definition of Success requires all puzzles: revisit rooms with incomplete Puzzles Found counts, collect omitted memento props, and check the layouts you have visited. Completing one room with one set of choices leaves its alternatives to collect.
Before repeating a whole life for a missing achievement, compare the Wall card with Room Puzzles. An unchecked entry points to the object work still needed; an incomplete Momentos Chosen count points to an alternative golden-box choice. Use the room tables to fix that gap, then confirm through the star and check the Wall again.
