Play Games & Game Center

Leaderboards and achievements ship built-in for both stores:

Android — Google Play Games Services
iOS — Apple Game Center

Both are optional. Leave the corresponding *_IS_ENABLED flag at false and the sign-in prompt never shows.

Play Games setup (Android)

Play Games needs an App ID — a numeric project ID that Play generates for you. Without it, the Google sign-in sheet appears but the app never receives a signed-in player.

Open the Google Play Console → your app.
Go to Grow → Play Games Services → Setup and management → Configuration.
Follow the flow to link a Google Cloud project. Play issues you a numeric APP_ID.

In setup.html → Configurations → Play Games, paste it into GAMES_ANDROID_APP_ID.

The sync step patches this into AndroidManifest.xml as the com.google.android.gms.games.APP_ID meta-data value.

Game Center setup (iOS)

Game Center is bound automatically by bundle ID and needs no manifest entry. You just need to enable the capability in App Store Connect:

Open App Store Connect → your app → App Information.
Enable Game Center for your app.

Leaderboards

Once Play Games (Android) and Game Center (iOS) are set up:

Create a leaderboard in each store console. Note the IDs — they're independent per store.
In setup.html → Configurations → Leaderboards enter:
- LEADERBOARD_IS_ENABLED = true
- LEADERBOARD_ANDROID_ID
- LEADERBOARD_IOS_ID

Achievements

The app has eight built-in achievement keys — the events that fire an unlock:

Key	Fired when
`first_guess`	Player solves their first logo
`ten_guesses`	10 logos solved total
`fifty_guesses`	50 logos solved total
`hundred_guesses`	100 logos solved total
`all_guesses`	Every logo across every mode solved
`first_level_complete`	First level fully completed
`no_hints_guess`	A logo solved without using any hint
`share_logo`	Player shares a logo with a friend

For each key you want to expose:

Create the matching achievement in Play Games and in Game Center. Note down the two IDs — they're separate per store.
In setup.html → Configurations → Achievements, add a row with:
- key — one of the eight keys above.
- androidId — Play Games achievement ID (leave empty for iOS-only).
- iosId — Game Center achievement ID (leave empty for Android-only).

Only keys listed here fire an unlock. Unlisted keys are silently skipped, so you can ship a subset if you want.

Set ACHIEVEMENT_IS_ENABLED=true.
