Remember Numbers with AdMob and Leaderboard

Introduction

Remember Numbers is a popular mobile game that challenges users to remember and recall numbers in a specific sequence. It's a great way to test one's memory and concentration skills. By incorporating AdMob and Leaderboards into the game, you can monetize the game and encourage users to play and improve their skills. In this tutorial, we will cover the steps to integrate AdMob and Leaderboards into the Remember Numbers game.

Prerequisites

• Remember Numbers game source code
• AdMob account
• Firebase account
• Android Studio (or Xcode for iOS)

Step 1: Set up AdMob

1. Create a new AdMob account if you haven't already. Go to the AdMob website and sign up for an account.
2. Create a new ad unit for your app. Go to the AdMob dashboard, click on "Apps" and then click on the "Create Ad Unit" button. Fill in the required information, including your app name, ad type (banner or interstitial), and ad size (depending on your game's UI).
3. Once you have created your ad unit, you will receive an ad unit ID. Note this down as you will need it later.

Step 2: Set up Firebase

1. Create a new Firebase project. Go to the Firebase website and sign in with your Google account. Click on "Create a project" and follow the prompts.
2. Install the Firebase SDK in your Remember Numbers game. You can do this by adding the Firebase library to your Android project (for Android) or your Xcode project (for iOS). Follow the Firebase documentation for detailed instructions.

Step 3: Set up Leaderboards

1. In your Firebase project, go to the "Auth" tab and enable Google Sign-In for your app. This will allow users to authenticate and link their scores to their Google account.
2. Create a new leaderboard in Firebase by going to the "Leaderboards" tab. Click on the "Create Leaderboard" button and fill in the required information, including your leaderboard title, description, and scoring mechanism.

Step 4: Integrate AdMob and Leaderboards into the Remember Numbers game

1. In your Remember Numbers game code, add the AdMob and Firebase SDKs to your project. This will typically involve adding a few lines of code to your project's build.gradle file (for Android) or Podfile (for iOS).
2. Initialize the AdMob SDK by adding the following code to your game's entry point (e.g. the main activity or view controller):

   
   // For Android
   import com.google.android.gms.ads.AdView;
   import com.google.android.gms.ads.MobileAds;

// In the onCreate method MobileAds.initialize(this, new OnInitializationCompleteListener() { @Override public void onInitializationComplete() { AdView adView = findViewById(R.id.adView); adView.loadAd(new AdRequest.Builder().build()); } });

```swift
// For iOS
import GoogleMobileAds

// In the application(_:didFinishLaunchingWithOptions:) method
GADMobileAds.sharedInstance().startLoadingAd()

1. Initialize the Firebase SDK by adding the following code to your game's entry point:

   
   // For Android
   import com.google.firebase.FirebaseApp;
   import com.google.firebase.auth.FirebaseAuth;

// In the onCreate method FirebaseApp.initializeApp(this); FirebaseAuth.getInstance();

```swift
// For iOS
import Firebase

// In the application(_:didFinishLaunchingWithOptions:) method
FirebaseApp.configure()

1. Implement the AdMob and Leaderboard code in your game's UI:

• For AdMob:

  // For Android
  AdView adView = findViewById(R.id.adView);
  adView.loadAd(new AdRequest.Builder().build());

// For iOS
GADBannerView adView = [[GADBannerView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
[GADMobileAds.sharedInstance requestView:adView];

• For Leaderboards:

  // For Android
  FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
  String userUID = firebaseAuth.getCurrentUser().getUid();
  Leaderboard leaderboard = FirebaseFirestore.getInstance().collection("leaderboards").document(userUID).get();

// For iOS
FIRFirestore *firestore = [FIRFirestore firestore];
FIRDocumentReference *leaderboardReference = [firestore collectionWithPath:@"leaderboards"].document;
FIRDataSnapshot *leaderboardSnapshot = [leaderboardReference getDocument];

1. Update the leaderboard score:

   // For Android
   long score = 100; // adjust the score as needed
   FirebaseAuth firebaseAuth = FirebaseAuth.getInstance();
   String userUID = firebaseAuth.getCurrentUser().getUid();
   FirebaseFirestore db = FirebaseFirestore.getInstance();
   db.collection("leaderboards").document(userUID).set(score, SetOptions.merge());

// For iOS
long score = 100; // adjust the score as needed
FIRAuth *auth = [FIRAuth auth];
FIRUser *user = [auth currentUser];
FIRFirestore *firestore = [FIRFirestore firestore];
[Firestore collectionWithPath:@"leaderboards"].document(user.uid).set([FIR.firestore_set_options(merge:true) score]);

Step 5: Test the game

Run the Remember Numbers game on a physical device or emulator and test the AdMob and Leaderboard features. Verify that ads are being displayed correctly and leaderboard scores are being updated correctly.

Conclusion

In this tutorial, we have covered the steps to integrate AdMob and Leaderboards into the Remember Numbers game. By following these steps, you can monetize your game and encourage users to play and improve their skills. Remember to replace the sample code with your own implementation and to adjust the leaderboard scoring mechanism as needed. Good luck with your game development!
