This guide family shows how to build a leaderboard with Redis sorted sets and per-user metadata.

## Overview

Leaderboards are a natural fit for Redis because sorted sets keep members ordered by score while still allowing fast updates and range queries.

This pattern works well when you need to:

* Track scores for players, users, teams, or other ranked entities
* Fetch the top `n` entries quickly
* Show entries around a specific rank position
* Keep only the highest-ranked entries, such as the top 100
* Store richer user details separately from the ranking score
