# Bi Kelime (A Word): A Trivia-Word Guessing Game built with Flutter. # Bi Kelime (A Word) ### Watch the Video ### Let's Get to Know the Game First of all, Bi Kelime means "A Word" in Turkish. Since I am a fan of trivia shows, I wanted to develop my own game. Here are some details about the game and how to play it: - Each game includes 5 questions. They are called *rounds*. - At the beginning of each round, the player first sees the question. - There is a bonus mode countdown button. - So if the player thinks that he/she can answer the question without seeing the hint boxes, he/she can tap that bonus answering mode button. The earlier the tap, the more the bonus multiplier will be. - In bonus answering mode, there are no hint letters are shown to the player. So, it makes it harder to answer the question. - Whereas in normal answering mode, the player sees the hint letters. As time passes, a random letter of the correct answer is revealed but the point multiplier also decreases. - If the player can type and answer the question correctly, the player wins that round. Then the points are calculated. - If there is no time left, then the player fails and no points are given. ### Key Takeaways - Flutter is a really powerful framework. In the right hands, Flutter can be used to create beautiful and monetizable mobile games. - Bi Kelime supports multiple languages in terms of the game language, the question language, and the answer language. - Bi Kelime is powered by a PostgreSQL database. Again, I have used my favorite backend tool Hasura for this job. - I also used the "GQL Designer" tool that I have previously developed for designing the scheme of the database. You can read about it here: --> [GQL Designer](https://yasinarik.com/gql-designer-a-relational-db-designer-built-with-flutter-desktop) - Bi Kelime also has an *admin app* that only I and content creators can open via desktop. I use that for viewing and entering new questions. - I have used *Auth0* as the authentication provider. While I was developing Bi Kelime, I couldn't find an appropriate Flutter - Auth0 SDK. So, I wrote an SDK by myself. Auth0 is especially more useful than Firebase because with Auth0, you can develop custom cloud functions (*NodeJS* code) and run them on specific authentication flows. And it is *free*. I have used that functionality to sync Auth0 users with the user data on the Hasura - PostgreSQL database which is deployed on Heroku servers. - While developing Bi Kelime, I did not get any help from a UI&UX developer. I made all that look myself and I believe it will be loved. - The animations... There is a lot to say about animations in Flutter. I really love the approach of [simple_animations](https://github.com/felixblaschke) package that Felix Blaschke released. I have used that package, modified it a bit, and created some generalized & reusable widgets. - Apart from some pre-drawn assets like coins, gold bars, and diamonds, I did NOT use any pre-rendered animations. Everything is written in pure `.dart`. For example, the red clock that shows up when the time is up is created and animated by a piece of smart code. - ... I might update this list if anything else comes to my mind...
