Good adventures deserve a backup.

Sign in for cloud saving when connected, or play as a guest with local saves. Keep a portable backup of both games in one code.

02 /Make yourself at home

PLAY
Your worlds. Your progress.

Choose an adventure, return to the collection, and keep a backup of the progress you want to protect.

Just games. No pressure.

Play as a guest or use your account. No ads, chat, purchases, or public player profiles.

KEEP YOUR PROGRESS

The Save vault

One backup for the whole arcade. You can also bring in a save code from either of your original games.

A portable backup is a useful extra safeguard. Copy this code into a private note and replace it after important progress. It is separate from your account sign-in key.

Colony Below saves your progression and restores you at the Nursery, not in the middle of a fight. Blackjack also saves the current hand.
GAME GUIDE
A QUICK GUIDE

Make yourself at home.

Pick a game

Tap Play or Continue. Use ← Arcade to return to the collection. Games pause while you browse.

Make room to play

More space hides the arcade toolbar; Show arcade menu brings it back. A full-screen button appears in browsers that support it.

Guest or account?

Guests keep progress in this browser. Optional accounts store your progress online when signed in and connected. Check the saving status before closing. A site update does not automatically delete your local save, but use a backup before important changes.

Your sign-in key

Accounts use a randomly generated secret key, not your email or an existing password. Keep that key private. You need it to log in on another device; a game backup code cannot log you in.

Extra backups

Save vault exports both games. To restore earlier saves, use Restore / import, check the code, and confirm. The note containing your backup does not update itself.

Playing on two devices

Wait for a cloud-save confirmation before moving to another device. If two different saves need your choice, automatic uploading pauses. Back up the local progress, then choose cloud or device progress in My account.

This is an independent collection. Book-inspired games remain unofficial fan projects, not official releases from the authors.
YOUR PLACE IN THE ARCADE

Keep your adventures.

Welcome back.

Paste your secret sign-in key. No email address or password is needed.

Your key opens your account. Never post it, share it, or send it in a screenshot. A game backup code is different from a sign-in key.
PRIVATE · OWNER ONLY

The workshop.

Your private planning notebook. It is loaded from the server only after your owner permission is checked. It is not included in the public page or game backups.

Only save plans here, never passwords or payment information. This notebook does not change or publish the games.
CLEAR, NOT CREEPY

Privacy & your data

Play without an account

Guest progress is kept in this browser when local storage is available. Browser data can be cleared, so the Save vault offers a portable backup. Guest saves are not uploaded to the account database.

Optional cloud accounts

Signing up stores a random account ID, a one-way fingerprint of your random secret sign-in key, necessary sign-in sessions, game saves, a few previous save versions, and save times in the site’s Cloudflare D1 database. We do not ask for your name, email, birthday, or payment details. There are no player profiles, messages, ads, or analytics scripts in this arcade.

Your key and session

A necessary, secure sign-in cookie lasts up to 30 days. The site’s JavaScript cannot read that cookie. Your sign-in key is shown during account creation; save it privately. The database does not store the readable key. There is no email-based recovery. Anyone who gets your key can access the account.

What is and is not private

Players cannot view other players’ saves. The site operator and hosting provider administer the database; saves are not end-to-end encrypted. Cloudflare also handles ordinary connection information, such as IP addresses, to deliver and protect the website. This app does not add advertising trackers or sell player data. See Cloudflare’s privacy policy.

Control and delete your data

Use the Save vault to export your games. In My account → Account controls, use Delete my account and confirm with your sign-in key to remove the live account, sessions, saves, save history, and any private owner notes. Your own downloaded backups remain yours. Cloudflare recovery backups may retain deleted records temporarily according to its backup retention. Log out on shared devices.

Saving is not a guarantee

Changed progress is normally uploaded about every 30 seconds while signed in and online, and when leaving a game. Check the saving status or use Save now before closing. Network problems, storage limits, or an unexpected shutdown can delay saving. Two devices with different progress require a choice instead of silently overwriting each other. Keep occasional portable backups.

Cloud accounts open only after the site operator enables them. A parent or guardian should manage the site and review the privacy setup before inviting other children to use accounts. This notice is not a claim of legal certification.
