am stuck

GameAdapter.java 
public class GameAdapter extends RecyclerView.Adapter<GameAdapter.GameViewHolder> {

    private Game[] mGames;

    public GameAdapter(Game[] games) {
        mGames = games;
    }

    @Override
    public GameViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.game_list_item, parent, false);
    holder.bindGame(mGames[position]);
    }

    @Override
    public void onBindViewHolder(GameViewHolder holder, int position) {
      GameViewHolder = new GameViewHolder(view); 
        return ViewHolder;  // Task 3
    }

    @Override
    public int getItemCount() {
       return mGames.length; 

    }

    /* Add your code here */
    public class GameViewHolder extends RecyclerView.ViewHolder {
        public TextView mTitleLabel;

        public GameViewHolder(View v) {
            super(v);
            mTitleLabel = (TextView)v.findViewById(R.id.titleLabel);
        }

        public void bindGame(Game game) {
            mTitleLabel.setText(game.getTitle());
        }
    }
}

Looks like you have the method bodies for onCreateViewHolder and onBindViewHolder partially swapped.

Move this back to onBindViewHolder:

holder.bindGame(mGames[position]);

And this back to onCreateViewHolder:

GameViewHolder holder = new GameViewHolder(view);
return holder;

    @Override
    public void onBindViewHolder(GameViewHolder holder, int position) {

        holder.bindGame(mGames[position]);
    }

    @Override
    public int getItemCount() {
        // Task 1
        return mGames.length;

    /* Add your code here */
    public class GameViewHolder extends RecyclerView.ViewHolder {
