Daily coding challenge — one new problem every day across 3 difficulty levels (easy/medium/hard), so you can pick what fits your level. Think Wordle, but you write code. - New problems daily, auto-generated and curated - 20 languages supported (Python, C++, Java, Go, Rust, and even Brainfuck lol) - Streak tracking to build a daily habit - Weekly / all-time leaderboards - Runtime-based ranking (see how fast your solution is vs others) - Public/private solutions - Achievement badges
