Snoo Drop

A physics-based timing game for Reddit Devvit. Drop Snoo from a swinging crane and land as upright as possible within three attempts.

Comment

Inspiration

As someone who's played PC games since childhood, I've always dreamed of creating my own. But the traditional game development process seemed overwhelming until I discovered Reddit's hackathon on Friday. The timing was perfect: I had a weekend to spare and a long-overdue goal to finally build something.

The idea came from the classic "Flip the Bottle Challenge" that went viral years ago. I loved how simple yet engaging it was just physics, timing, and that satisfying moment when you nail the landing. I thought, "What if I could recreate that feeling but with Reddit's mascot, Snoo?"

Working in IT as a cybersecurity analyst, I'm comfortable with coding, but game development was uncharted territory. With AI tools making development more accessible than ever, I saw this as my chance to turn a weekend idea into reality. Reddit's Devvit platform removed all the friction ,no complex deployment, no app store approvals, just build and play.

What it does

Flip the Snoo Challenge is a physics-based timing game where players drop Snoo from a swinging crane and try to land it as upright as possible.

Here's how it works:

  • Snoo dangles from a crane that swings like a pendulum
  • Players have 3 attempts and 60 seconds to get the best landing
  • Tap to release Snoo mid-swing , timing is everything!
  • Snoo rotates during free-fall based on release momentum
  • Scoring is based on how upright Snoo lands (0° = perfect, 180° = upside down)
  • Time bonus rewards quick, confident players
  • Compete on daily and all-time leaderboards

It's easy to pick up but surprisingly hard to master , just like the bottle flip challenge that inspired it.

How we built it

I built this game in a 48-hour sprint over the weekend using Reddit's Devvit framework.

Tech Stack:

  • Devvit Web for the Reddit integration
  • React + TypeScript for the game logic and UI
  • Canvas rendering for smooth physics animations
  • Matter.js-inspired physics for realistic pendulum and gravity simulation
  • Custom audio cues for drop, impact, and timer sounds

Development Process:

  1. Friday evening: Discovered the hackathon, brainstormed ideas, settled on the bottle flip concept
  2. Saturday: Full grind mode , built the core physics engine, pendulum mechanics, and basic UI
  3. Sunday: Added scoring system, leaderboards, audio, polish, and final testing

I leveraged AI coding assistants heavily to accelerate development. While I'm comfortable with coding from my cybersecurity background, AI helped me quickly prototype game mechanics I'd never built before , like pendulum physics and rotation calculations.

Biggest time-saver: Devvit's built-in leaderboard storage and Reddit authentication meant I could focus entirely on gameplay instead of backend infrastructure.

Challenges we ran into

The biggest challenges weren't coding-related—they were graphics, UI design, and audio.

Graphics & Design:

  • I wanted to use Reddit's official Snoo character, but due to time constraints, I settled on a simplified Snoo-like design
  • Creating smooth, visually appealing animations in canvas required lots of trial and error
  • Balancing a clean, minimal UI with clear feedback was harder than expected

Physics Tuning:

  • Getting the pendulum swing to feel "right" took dozens of iterations
  • Rotation speed during free-fall needed careful calibration ,too slow felt boring, too fast felt chaotic
  • Landing angle detection had to be precise but forgiving enough to feel fair

Audio Implementation:

  • Finding/creating royalty-free sound effects that matched the game's feel
  • Timing audio cues perfectly with visual events (drop, impact, timer ticking)
  • Making sure sounds worked across different browsers and devices

Time Pressure:

  • Knowing I had to finish by Sunday (work starts Monday) forced tough prioritization decisions
  • Had to cut planned features like multiple difficulty levels and power-ups

Despite these hurdles, coding itself was smooth thanks to TypeScript, AI assistance, and Devvit's excellent documentation.

Accomplishments that we're proud of

🎮 Actually finished a game! After years of wanting to create my own game, I finally did it in just one weekend.

⚡ Nailed the "feel": The pendulum swing and landing physics feel satisfying and responsive. That moment when you nail a perfect upright landing is genuinely rewarding.

🏆 Built a complete experience: This isn't just a tech demo - it has scoring, leaderboards, audio, UI polish, and replayability. It's a real, playable game.

📱 Zero friction deployment: Players can jump in and play directly on Reddit - no downloads, no accounts, just click and play.

🤖 AI-accelerated development: Proved to myself that with modern tools, a solo developer can build something polished in 48 hours.

💪 Learned an entire game development workflow in a weekend - from physics simulation to audio integration to deployment.

What we learned

Game design is all about iteration: My first version had completely different physics. Through playtesting and tweaking, I discovered what made the game actually fun.

Constraints breed creativity: Having only a weekend forced me to focus on the core mechanic and make it great, rather than adding half-baked features.

Physics = feeling: Small changes to gravity, rotation speed, or pendulum frequency dramatically changed how the game felt. Tuning these values was more art than science.

Sound matters more than I thought: Adding audio cues transformed the experience from "meh" to genuinely engaging.

AI is a force multiplier: I could focus on creative decisions while AI helped with implementation details. It's not about AI replacing developers, it's about amplifying what we can build.

Reddit's platform is genuinely accessible: As someone who's never published a game before, Devvit made it shockingly easy. No app store politics, no complex servers, just build and ship.

I want to do this again: The satisfaction of seeing people play something I built is addictive. This won't be my last game.

What's next for Snoo Drop

This is just the beginning! Here's what I'm planning:

Short-term updates:

  • ✅ Official Reddit Snoo graphics: Replace placeholder with proper Snoo artwork
  • 🎯 Three difficulty levels:
    • Easy: Slower pendulum, larger landing zone
    • Medium: Current gameplay
    • Hard: Faster swing, stricter angle scoring
  • 🎨 Visual polish: Better animations, particle effects on perfect landings, improved UI

Medium-term features:

  • 🏅 Daily challenges: Special objectives like "Land within 10° three times in a row"
  • 🎪 Themed events: Holiday skins, special backgrounds
  • 📊 Better stats tracking: Personal bests, success rate, average angle
  • 🔊 More audio variety: Celebratory sounds for perfect landings, different impact sounds based on angle

Long-term vision:

  • 🌟 Power-ups: Slow-motion mode, guided landing assists (for accessibility)
  • 👥 Multiplayer mode: Head-to-head landing competitions
  • 🏆 Weekly tournaments: Compete for special badges/flair
  • 🎮 More game modes: Maybe a "stack the Snoos" mode inspired by my original concept

Community-driven development:

  • I'll be actively listening to player feedback in the comments
  • Open to suggestions for features and improvements
  • Might open-source parts of the codebase to help other aspiring Reddit game developers

The goal is to keep Snoo Drop fresh with regular updates while starting work on new game ideas. I've already got concepts brewing for a puzzle game and a rhythm-based challenge.

This weekend proved I can ship games, now I want to build a whole portfolio of Reddit mini-games that bring joy to the community.

Thanks to Reddit for making game development accessible, to the AI tools that accelerated my coding, and to everyone who plays and shares feedback. This is just the start! 🚀
