The Trivia app template lets you create apps without writing a single line of code. The template lets you choose a personality and specify the questions, answers, and configuration for the app in a Google Sheet. Then, after completing these quick steps, you'll have a fully working app that you can test and submit for approval.
Build your app
To build your app using a trivia template, do the following:
- Go to the Actions Console and log in with your Google account.
- Click on Add/Import Project to create a new project. The Add project window appears.
Give the project a name and click on Create Project.
Under More options, pick Templates.
Click on the Trivia option. You'll now be taken to an Overview page where you can enter information about your Action.
Click Build > Actions, followed by Add your first action.
In the Create Action window, you should see the Trivia option appear. Click Build.
(Optional) If you want to use a language other than English, select which language you want your app to use in the drop-down menu at the top by clicking Add language and selecting a language.
In the Personality section, select one of the available personality options and click Next.
Use the players below to hear audio samples of each personality. Note that not all personalities are currently available in every language.
Voice Sample Regal Queen Mr. Montgomery Beeps the Robot
Each personality has different spoken prompts and sound effects that users hear as they play the game.
In the content section, click on Bulk upload the content for your app using Google Sheets. You will see the following prompt:
Click on the Make a copy of the pre-filled Google Sheet for editing link and click Make a Copy.
Update the Questions & Answers tab of your sheet copy with your own questions and answers. Try adding fun follow-ups that give users extra facts about the answer.
Update the Configuration tab of the sheet with the name of your app. You can further customize your game by optionally assigning a difficulty and/or category to each question, and provide custom sounds via audio URLs. For more information on custom configuration options, see the configuration parameters section.
When you finish filling out the sheet, go back to the Actions Console and click Next to move on to the Connect Sheet step.
Copy and paste your Google Sheet's URL into the Add your sheet's URL to upload your content field and click Upload:
Click on Create App. The Overview page appears, showing you a notification that says Created. It might take a minute before the page refreshes and the notification appears.
Add question difficulty and/or category
You can optionally configure your trivia app's questions to be grouped by up to three difficulty levels, custom categories, or both. When users invoke your app, they will be prompted to select the difficulty and/or category level at the start of each game. On a device with a screen, the user is presented with suggestion chips to select the category or difficulty level.
You can use this example trivia game sheet with both question difficulties and categories to get started.
The following sections describe how to add difficulty levels and/or categories to your quiz:
Difficulty levels - To add difficulty levels to your questions, add a column to your sheet's Questions & Answers tab titled "Difficulty/Grade Level", then add a difficulty or grade level to each question in your sheet. You can denote up to three different difficulty levels, e.g. "Easy," "Medium," and "Hard."
- You may also want to set some custom configuration parameters, namely DifficultyOrGradeLevelPrompt, DefaultDifficultyOrGradeLevel, and DifficultyOrGradeLevelSuggestionChip1/2/3.
Categories - To add categories to your questions, add a column to your sheet's Questions & Answers tab titled "Category/Topic, then add a category or topic to each question in your sheet. You can denote up to three different categories, e.g. "Science," "Math," and "General Knowledge."
- You may also want to set some custom configuration parameters, namely CategoryOrTopicPrompt, DefaultCategoryOrTopic, and CategoryOrTopicSuggestionChip1/2/3.
Difficulty levels and categories - To add both difficulty levels and categories to your questions, follow the instructions above to create and populate both the "Difficulty/Grade Level" and "Category/Topic" columns.
- In addition to the configuration parameters above, you may also want to set FirstChoice and SecondChoice.
Edit the content of your app
If you want to change your app's content, navigate to Overview on the left navigation bar, then hover over Actions and click the pencil icon followed by Trivia actions.
From there, you can follow the instructions under Content again to re-upload your sheet to reflect any changes.
Add additional languages to your app
Once you've successfully uploaded a Google Sheet for your first language, you can add additional languages by uploading additional sheets for each new language. Follow the editing content instructions above to navigate to your template setup, then add a new language using the language drop-down on top.
You'll be prompted to select a personality and upload a new sheet, so follow the Building your app instructions above to walk through the setup for each language.
You can customize your app with categories, difficulty and grade levels, or even custom audio files to build your own personality. To configure a custom option, type the key and value in the Configuration tab of your sheet.
You can add the following optional keys in the Configuration tab of the Google Sheet to further customize your app:
||The "ding" sound that is played after each question to prompt the user for their response.||Audio URL|
||The intro music played when the game starts.||Audio URL|

Test your app
Click on Simulator in the left column to test your app via a web interface. To invoke your app, say or type Talk to my test app in the simulator. You can also test your app via Google Assistant on your phone or voice-activated speaker if your device and app are using the same Google account.
Submit your app
When the Actions section is complete and you have tested your app, you may submit your app to Google for review. If your app is approved, it will be available to Assistant users.
To submit your app, do the following:
Go to the Overview page for your project in the Actions Console.
Navigate to Setup > Invocation.
- Invocation name: Enter your app's invocation name. This name is how users invoke your app.
- Directory title: Enter your app's name for the directory. This name is presented to users in the Assistant Directory.
- Google Assistant voice: Pick which voice you would like your app to use. You can hear audio samples of each voice on the Languages and Locales page.
Navigate to Deploy > Directory information.
- Details: Add your app's introduction, short description, and a full description that clearly explains what the app is used for and what it does. You also need to add useful sample invocations,
- Images: Add two images, one for the banner and one for the logo.
- Contact details: Add an email contact. Our review team uses this email address to give feedback on your app. Users can also see this email address to contact you.
Category: Select the most appropriate category for your app to live under in the Assistant Directory.
For Families: If you would like your app to be targeted to kids and families, select Yes.
Alcohol and Tobacco: If your app references alcohol or tobacco at all, select Yes.
- Testing Instructions: Add any specific testing instructions if required. These are only visible to our review team. Generally, for apps that you build with the trivia template, you can leave this blank.
- Transaction: Template apps don't perform Transactions, so you can leave this blank.
Navigate to Deploy > Release.
- If there are any error messages on the top, you should follow the instructions provided to address the issue. Otherwise, click Submit for production.
If your app isn't working, see if you're running into one of the issues below and try following the recommended troubleshooting steps:
Change the default title in the Configuration tab of your Google Sheet
Go back to your content sheet and open the Configuration tab. Change the name of the app by using a new title instead of The Fun Trivia Game. Go to the Actions Console and connect the sheet again.
Unsupported Google Sheet Configuration tab key
This error means one of the key-value pairs in the Configuration tab of the your content sheet is incorrect. Refer to list of Configuration Parameters and make sure your keys are all spelled correctly.
Failed to get conversion
If you see this error, refresh the web page and try again.
Request Access Error
You might see a screen requesting access permission when you try to access the pre-filled template content sheet. If this occurs:
- Log out of all Google accounts and close all browsers.
- Reopen your browser and log back in with the account that you're using for your Actions Console project.
- If the error message persists, try using Incognito mode in Chrome.
Simulator Not Responding
If the simulator doesn't show the Test or Authorize button, refresh the web page and try again.
Content Best Practices
- Question Format:
- Keep questions clear and short. Don't force the user to hold a lot of words in their heads.
- Keep the answers even shorter. One or two-word answers work best.
- Make sure your questions are actually asking the user a question.
- Try to start with question words such as who, what, or when. Guide users to the kind of answer they should give.
- Since users can't interrupt a question, it's helpful to introduce
a list of answers with "Which of these options…" Users might try to
answer a question before they hear them all, so let them know that
more are coming.
- Ordinal answers like first one, 3rd, and second option are understood by the Assistant as valid responses to multiple-choice questions, so your users can respond however feels the most natural to them.
- Synonyms: If you think there are multiple correct ways to answer a question, you can set multiple synonyms by using the "|" key as a separator. For example, if a question's answer is set to "United States|USA|US", a user could say any of these synonyms to correctly answer the question.
Engagement: To vary the questions and keep things moving, try to mix in different types of questions (like true or false).
Cultural Reach: To engage the maximum number of users, try to offer questions that many people can relate to, regardless of their ethnic or class background. Remember that not everyone has been exposed to the same classical and cultural references.
- Understandability: Answers work best when they require three or fewer words. If the user has to give a lengthy response, the voice-detection error gap widens.
- Efficiency: It's best to use contractions wherever possible ("I'm" instead of "I am") to speed up TTS playback.
- Age Appropriateness: Determine your target audience before you create your questions and answers. We recommend targeting your content for age appropriateness.
- Gender Diversity: For maximum user engagement, remember that you're targeting diverse genders. Try to use pronouns, examples, and subject matter that a maximum number of users can relate to.
General Guidelines and Restrictions
- The maximum question length is 200 characters.
- Try not to include complicated or very long words that may be hard for the computer speech to pronounce or users to understand. For example, mechanoreceptors or proprioceptors.
- Do not ask two questions such as "How many x are there? What are they?" as a part of one single question.
- The maximum answer length is 25 characters.
- The maximum questions per round is 10 questions.
- You can add up to 1000 questions per app. If you have more than 1000 questions, you can replace the content periodically, or create multiple apps and categorize the questions accordingly.
- In the absence of a follow-up statement, leave the cell empty. Do not add programming characters such as \n, \n\r.
Refrain from using questions with multi-word answers that have overlapping words. For example:
- Question: What are the necessary ingredients for XYZ?
sunlight, carbon dioxide, and water
sunlight, carbon dioxide and oxygen
sunlight, oxygen and water
Be cautious while using multi-word, non-overlapping answers, because it might be difficult for users to repeat back the whole answer. For example:
- Question: What are the necessary ingredients for XYZ?
sunlight, water, carbon dioxide
oxygen, nitrogen, selenium
Do not include special characters such as "^", ":" , "(" , ")"
- You may include "&", "$", "#", "@" in your questions and answers. If you do, please test them on a device to ensure they are spoken correctly and the answers are speech-recognized correctly.
- If you have abbreviations or mathematical symbols as a part of the question or answer, make sure you test each phrase to hear how the Assistant speaks it and if the speech recognition works. For example, "O2" (for oxygen), "NAACP," and "a+b=c+d" may not be spoken or speech-recognized as you expect.
- To test how the Assistant speaks a single question containing the abbreviations or symbols, update the sheet to contain that single question as the first question, set 'RandomizeQuestions' = 'No', and re-test it with the Actions simulator.
