Free Online Marble Race Simulator: Turn Random Draws into Exciting Events

Ditch the boring lists. Let physics decide your destiny!

Whether you are hosting a giveaway on Twitch, deciding where to eat lunch, or sorting teams for an event, traditional random number generators can be dull.

Marble Run is a visual randomizer that combines realistic physics with pure chance. Powered by the Box2D physics engine, every race is unique. Gravity, collisions, and friction interact in real-time to create an unpredictable and entertaining spectacle, ensuring fairness while keeping your audience engaged.

Why use our Marble Simulator?

1. Realistic Physics Core: Built on the same engine used in “Angry Birds”, ensuring authentic rolling, bouncing, and collisions. No pre-scripted animations.
2. Fair & Unbiased: We use a precision grid-start system. Every marble’s starting position is calculated to ensure equal opportunity, eliminating “spawn advantage.”
3. No Install Needed: Runs smoothly in your web browser on both desktop and mobile. All calculations are client-side for zero latency.

Game Modes & Maps

Adapt the game to your specific needs with our versatile modes:

1. Exciting Game Modes

• 🚀 Race Mode:

  • Rules: Classic speedrun. The first marble to cross the finish line wins.
  • Best For: Top 3 rankings, determining priority, or standard giveaways.
  • Feature: Automatic Photo Finish. The game slows down to slow-motion when the leader approaches the goal, ensuring a dramatic and clear winner.

• ☠️ Survival Mode (Battle Royale):

  • Rules: The floor is lava! Marbles that fall through the bottom are eliminated. The last marble remaining on the map is the winner.
  • Best For: Grand prizes, “last man standing” contests, or determining punishments.
  • Feature: Final Duel Zoom. When only two marbles remain, the camera automatically zooms in and slows down for maximum tension.

2. Diverse Map Designs

• Wheel of Fortune: A classic funnel design that tests a marble’s ability to navigate through chaos.
• Classic Pachinko: A pin-filled obstacle course with an hourglass bottleneck. Marbles will jam, stack, and burst through, creating thrilling comeback moments.

Advanced Features for Streamers

Designed with content creators in mind to maximize viewer interaction:

• Bulk Import: Supports Name*Count syntax (e.g., ViewerA*10) to easily handle hundreds of entries or weighted probabilities.
• Smart Camera:
  • Auto-Follow: Automatically tracks the leader (Race) or the most at-risk marble (Survival).
  • Minimap Peek: Hover over the minimap in the top-left corner to manually scout the track, then automatically snap back to the action.
• Live Leaderboard: A transparent overlay shows real-time rankings. Finished (or eliminated) marbles are automatically checked off.
• Chaos Factor: (Easter Egg) Marbles occasionally emit a small “self-destruct” impulse to prevent jams and add a layer of unpredictability.

How to Use

1. Enter Names: Paste your list into the input box on the bottom left. Increase odds by using Name*Number.
2. Configure:
   • Select your preferred Map from the right-hand menu.
   • Toggle between Race or Survival mode.
3. Start: Click the 🚀 GO! button to launch the marbles.
4. Results: Once the race concludes, the winner is displayed prominently in the “Current Champion” box with celebratory effects.

FAQ

Q: Is the result truly random? A: Yes. While the physics laws are constant, micro-variations in floating-point math and our added “chaos impulses” ensure that every run is unpredictable and effectively random.

Q: How many marbles can I run? A: We recommend keeping it under 1000 for the smoothest 60 FPS experience, though modern devices can handle hundreds easily.

Q: Can I use this on my stream (Twitch/YouTube)? A: Absolutely! The tool is free, ad-free during gameplay, and has no watermarks, making it perfect for broadcast overlays.
