21Goals: Custom Football Prediction Platform

The game rules shaped the build

21Goals needed custom prediction and scoring rules, round management, and competition between players. We mapped those rules alongside the administration tasks needed to run the game.

The build joined four parts of the product:

• Prediction flows and scoring: player entries and the custom logic used to calculate scores.
• Rounds and administration: workflows for managing games, rounds, users and results.
• Mini-leagues and leaderboards: rankings that let players compete in smaller groups.
• Football-data integrations: fixture, player and match information used by the application.

The player experience needed an operating side

A prediction interface is only part of the product. The team running it also needs to manage rounds and results. We developed those administration workflows alongside the player-facing application.

The architecture combined React-based interfaces, football-data APIs and backend processing for the game’s rules and workflows.

Delivered functionality

The delivered application connected prediction entry, custom scoring, mini-leagues, leaderboards and game administration. The workflow illustration above shows how these capabilities relate.
