Telegram quiz bot for solo, group, and duel games with ELO rankings
It lets Telegram users play quiz games alone or with friends, offering solo rounds, group lobbies, and 1‑on‑1 duels. The bot stores questions and player stats in PostgreSQL, while Redis handles fast matchmaking, timers, and atomic answer checks via Lua scripts. Built with Java 21 and Spring Boot, it provides multilingual support, ELO‑based rankings, and visual result cards rendered from SVG. Ideal for community admins or anyone wanting an engaging, self‑hosted quiz experience on Telegram.
