Inspiration

SubSleuth was inspired by the success of daily puzzle games like Wordle and Heardle. We realized Reddit's diverse communities have incredibly distinct voices and posting patterns - from the practical advice of r/AmItheAsshole to the oddly satisfying content of r/oddlysatisfying. This creates a perfect opportunity for a fun, challenging daily game that celebrates Reddit culture.

What it does

SubSleuth is a daily subreddit guessing game that tests your knowledge of Reddit. Players receive 7 rounds of increasing difficulty, starting with 2 subreddit options and scaling up to 6. Each round shows a real Reddit post title and optional body text. Players must identify which subreddit it belongs to before time runs out.

Key Features:

  • 7 daily rounds with progressive difficulty
  • Speed scoring (up to 200 points per round: 100 base + 100 speed bonus)
  • Per-round timers that get progressively tighter
  • Streak tracking for daily players
  • Community leaderboards
  • Wordle-style share grid to challenge friends
  • Stats dashboard showing games played, win rate, perfect games, and score distribution
  • User submission system for puzzle suggestions
  • Dark mode support matching Reddit's theme

How it was built

SubSleuth is built on Reddit's Devvit platform, allowing it to function as a native Reddit experience. The app was developed using TypeScript and React to create an interactive, responsive interface. We implemented a curated database of 50+ subreddits with hand-selected posts that capture each community's unique voice.

Technical Architecture:

  • Devvit framework for Reddit native app
  • React for UI components
  • TypeScript for type safety
  • Redis for leaderboard and streak tracking
  • User submission validation system
  • Responsive design for mobile and desktop
