Printable Escape Room Kit for Kids, Teens and Adults, 3 Difficulty Levels, Offline Answer Checker App, Family Game Night, Birthday Party

The Inventor's Vault is a printable escape room for kids, teens and adults, for family game night. Print-at-home PDFs and an offline answer checker app, phone, tablet or computer. Instant download.

You want a game night the 9-year-old and the grown-ups can play together: no answer envelope on the table waiting to give the ending away, no hour of cutting before anyone plays, and nobody stuck being the referee. Professor Hazel Sprocket has flown off in her hot-air balloon and locked her greatest invention in her vault, and your team has one hour to open it. One story at three levels, 12 locks in each, and a Game Master app that checks every answer offline, holds 108 hints, three for every lock, and keeps the ending locked until the final answer opens it. Scissors have just two jobs, the Shredded Letter and the Punch Card's rings, and setup takes about 10 minutes.

Print one level's Player Pack, keep the Mission Brief on the table, sort the other 13 pages into four envelopes, open the app on the same level and start the clock. The Party Extras are fillable; no Canva needed.

📦 WHAT'S INCLUDED (22 FILES)
————————————————————

Every PDF comes twice, in a US-Letter folder and an A4 folder, page for page the same.

01. Game Master app and install card (2 files)
Game-Master-App.html, one file that runs offline: level select, one team or a team race, a clock with a pause button, answer checks, Tock the owl's hints, a progress map, the locked ending and a results screen. INSTALL-AS-AN-APP.txt puts it on a phone, tablet or computer as an app with its own icon.

02. Player Packs (12 PDFs)
Junior (ages 8 to 11), Teen (12 and up) and Expert (adults), 14 pages and 12 locks each, in color and in an ink-light black-and-white edition, on US Letter and A4. Page 1, the Mission Brief, stays on the table. The other 13 pages fill four envelopes: the Workbench, the Library, the Observatory and the Machine Room, which also holds the Vault Door page so the finale stays sealed until then.

03. Host Guide (2 PDFs)
20 pages: the story, setup in about 10 minutes, the print list, envelope labels, running the game with the app or without it, the flow chart, the puzzle types, team race and classroom notes, troubleshooting, and the HOST ONLY answer keys and ending at the back.

04. Hint Cards (2 PDFs)
10 pages: Tock's three-stage hints on paper for every lock at every level, for play without the app.

05. Party Extras (2 PDFs)
4 pages with 57 fillable fields: an invitation, team name badges, a Certificate of Escape and a scoreboard.

06. Quick-Start guide and START-HERE (2 files)
The two-page QUICK-START PDF with the four steps and what every file is for, and a plain-text START-HERE that names every file.

👤 WHO THIS IS FOR
————————————————————

A parent planning a family game night, a birthday party or something to do over the holidays for kids 8 and up, who wants the grown-ups at the table solving too, not reading from an answer key.

A teacher, youth leader or party host with a bigger group, who wants 2 to 4 teams racing on one device with a shared clock and a leaderboard.

Puzzle-loving adults who have done escape rooms before and want the Expert level: a jammed machine, mirror writing, a cryptogram with no key and a logic grid with 11 clues.

————————————————————
🚫 WHO THIS IS NOT FOR
————————————————————

Anyone looking for a boxed game with physical props, or for a scary or crime-solving party: this story is gentle, with no villains. Children under 8 can play Junior with a grown-up reading every page aloud.

————————————————————
✅ KEY BENEFITS
————————————————————

One story at three levels, each with its own puzzles and answers: Junior for ages 8 to 11 in about 45 minutes, Teen for 12 and up and Expert for adults in about 60. Every level was solved start to finish in blind testing, and every lock has exactly one answer, with its format shown on the lock.
Nothing spoils the ending: the app stores the answers only as scrambled codes and keeps the ending locked until the final answer opens it. Answer checks ignore capitals, spaces, commas, colons, dashes and leading zeros and accept a few common misspellings. No internet to play, no account, nothing sent anywhere.
108 hints, three for every lock at every level: a nudge, a hint, then the answer only when you ask for it. Every hint is counted on the results screen, with an optional time penalty for a race, and the same hints come printed on the Hint Cards.
Low cut, low ink: scissors have exactly two jobs, cutting the Shredded Letter into strips (4 straight cuts at Junior, 5 at Teen, 8 at Expert) and cutting the small rings out of the Punch Card (a grown-up does this at Junior). No other page is cut or trimmed, and every Player Pack also comes in an ink-light black-and-white edition.
Eleven kinds of puzzle in every level plus a vault that uses your earlier answers: gears, a blueprint, a shredded letter, a symbol script, a logic grid, a word ladder, clocks, a star chart, a picture to search, a punch card laid over a plate and a fold-in. The app is the game master, so the grown-up plays too: 1 to 8 players a team, or a race for 2 to 4 teams.

————————————————————
🔧 HOW IT WORKS
————————————————————

1. Print and sort. Print the Player Pack for your level, one copy per team, single-sided at 100% (14 sheets). Label four envelopes from the Host Guide's label page and sort the pages by its print list: the Mission Brief stays on the table, and the Vault Door page goes in Envelope 4. Setup takes about 10 minutes.

2. Play. In the app, choose the same level, name your team (or 2 to 4 teams for a race), read the mission aloud and start the clock. Players solve, cut, fold and type their answers. On Junior lock 7, The Four Clocks, the code 3215 shakes red with "Not that one. Check the page again." and the counter stays at 7 of 12; the code 3251 unlocks it and the counter reads Locks open: 8 of 12. When all nine room locks are open, the app says to open Envelope 4, the Machine Room, and the Vault Door lock opens only after locks 10 and 11.

3. Open the vault. The right final answer plays the secret ending and a results screen with the escape time, the hints used and the time each lock opened, ready to print or screenshot. Hand out the Certificates of Escape. No device at the table? The Host Guide's HOST ONLY keys and the Hint Cards run the whole game on paper.

❓ QUESTIONS BUYERS ASK
————————————————————

What format is this? 22 files in one zip: 18 PDFs (the Player Packs, Host Guide, Hint Cards and Party Extras, each on US Letter and on A4), the Game Master app as one HTML file, its install card, a two-page quick-start PDF and a START-HERE file. Ready to download the moment payment clears.

What do I need? Do I need Canva or internet? No Canva, no account and no internet to play. You need a printer and plain paper (14 sheets per team), 4 envelopes per team, pencils, and a pair of scissors per team. For the app, double-click the file on a computer and it opens in your web browser; on a phone or tablet, install it once with INSTALL-AS-AN-APP.txt from the download, and from then on it runs offline.

What does the app do? It checks each answer and says what to do next, gives Tock's three-step hints, runs the clock with a pause button, tells players when to open Envelope 4, wakes the Vault Door once locks 10 and 11 are open, plays the ending, and shows the escape time, the hints used and every lock's time. In a team race, each team taps its own name before answering, and the leaderboard ranks teams by time, plus any hint penalty, then by locks open.

Is it too hard for my 9-year-old? Has it been tested? Junior is written for ages 8 to 11 with a grown-up nearby: short instructions, full keys and worked examples, and Tock's nudges help without giving the answer away. Every level was solved start to finish in blind testing. The times are targets for a team of 3 to 6, and nobody is locked out when time runs out: the app counts the extra minutes.

⚠️ PLEASE READ
————————————————————

Print single-sided at 100% (Actual size). The pages are cut, folded and stacked, and the Punch Card lines up with the Card Reader Plate only when both are printed the same way on the same paper. Keep both of those pages whole: only the small rings are cut out of the card. The Folding Blueprint needs careful creases.

Match the level: the printed Player Pack and the level chosen in the app must be the same, because every level has its own answers.

On a phone or tablet, a file preview such as the iPhone Files app shows the HTML file but cannot run it: install the app with INSTALL-AS-AN-APP.txt, or play on a computer. A game is saved only on the device that runs it, and an installed copy starts empty.

The story plays any time of year; it is not a Christmas story. It is family-friendly, and every name in it is invented. The Party Extras fill in Adobe Acrobat Reader and most browsers, or print them blank and write by hand.
