League of Legends game information and match history

Archived2024.11 — 2025.01Team of 3

A League of Legends game information website developed by a three-person team. It uses the Riot Games API to provide player match-history searches, statistics, and champion and item information.

Background & purpose

Our team wanted to make player match history, match statistics, and champion and item information easier to find through a single website. We organized data retrieved from Riot Games APIs into a browsable game-information service.
