For the final project, I created a bot playing a song association game with humans. I watched several Youtube clips, and I thought it is intriguing to watch.

I decided to use Spotify API and Genius API to search song and lyrics information based on the user input.
So, if the Dialogflow detects the intent then it returns with fulfillment text or song lyrics with the input word included when the game is triggered.
