01
The daily show
One question set for everyone and one try a day. Eight or more right pays a bonus, a streak freeze bought with coins covers a missed day, and the worker fills the next seven days on its own.
Multiplayer quiz game · Flutter + Next.js
Own the quiz show.
A Flutter app for iOS and Android, a website where people play in the browser, and a control-room admin. Daily shows, live battles for up to eight, contests, weekly leagues and a question bank with CSV import and an AI writer.

one show.
Every screen below is the real product running on the demo server: the app talks to the same API the website and admin use.
02
Live battles
Quick match with anyone online (a bot steps in after 20 seconds), a code for a friend, or a room for up to eight. The server keeps time and scores; 1v1 winners take the pot, rooms split it 60 / 25 / 15.
03
Contests and weekly leagues
Scheduled contests with entry fees and prize pools paid out once by the worker. Every Monday players join a group of 30 in their tier; on Sunday night the top move up and the bottom move down, Bronze to Diamond.
04
A question bank that fills itself
An editor for six question types, CSV import of up to 5,000 rows with a check before saving, bulk publish and delete, and an AI writer (Claude, OpenAI or Gemini, your key) whose drafts wait for a person.

05
Coins that can't be farmed
Answers are checked on the server. Instant finishes pay nothing, levels pay up to a daily cap, rewarded ads pay only after Google confirms them, store purchases are granted once and refunds take coins back.
06
Play in the browser
The website plays the same levels, daily quiz and contests with a timer, lifelines and answer review. Player-made quizzes open from a link or QR code without signing up.
