Competitive trivia game

Jaweb

Independent build · shipped 2025 · retired

A living-room trivia night turned into a fair, automated product with payments.

Automaticreferee + scoring

The challenge

Turn an informal two-team quiz game into a product that referees itself, scores fairly, and takes payment — without a human host keeping track.

What it had to do

  • Two teams, six categories, and three difficulty levels
  • Rules, scoring and refereeing without a human host
  • Payments inside the app

My role

Sole engineer. Designed and built the whole app from scratch.

How I built it

  • Modeled two teams, six categories, and three difficulty levels with referee logic that enforces the rules.
  • Automated scoring so a full match runs without a human keeping score.
  • Integrated My Fatoorah payments and packaged it on a clean-architecture Flutter codebase.

The board — six categories, three point tiers per category, and each team's running score and lifelines pinned to the bottom corners.
Jaweb question view: a photo prompt with the question and its point value, a countdown timer, reveal and score buttons, and both teams' totals listed alongside.
A question in play: countdown timer, the point value at stake, reveal-answer and mark-correct controls, with both teams' totals and remaining lifelines alongside.
