Frequently Asked Questions

Yes! Roulette Rush uses a real physics engine (Matter.js) to simulate marble behavior. Every bounce, collision, and roll is calculated in real-time. Unlike basic random number generators, the outcome depends on actual physics simulation, making it genuinely unpredictable and fair. No predetermined results, no bias.

You can add up to 500 marbles in a single race. Use the name*count syntax (e.g., Alice*5) to create multiple entries for the same name, giving that name a higher chance of winning. The adaptive spawn grid system ensures smooth performance even with hundreds of marbles.

Absolutely! Roulette Rush is the perfect random name picker for teachers and classrooms. Use it for picking students for presentations, group assignments, or activities. No login required — just open the page and enter student names. It works on classroom projectors, tablets, and phones. Students love the marble racing format!

Enter your viewers' or subscribers' names (or paste a list), pick a map, and start the race live on stream. Your audience can watch the marble race in real-time, creating maximum engagement. Use the name*count syntax for weighted entries (e.g., subscribers get more marbles). It's the most entertaining giveaway picker for streamers.

Traditional wheel spinners (like Wheel of Names or Picker Wheel) show a spinning wheel that stops on a random name. Roulette Rush replaces that with physics-based marble racing — marbles bounce through obstacles, overtake each other, and race to a finish line. It's far more engaging and entertaining to watch, especially for audiences.

We offer 6 unique maps: Wheel of Fortune, BubblePop, Night Run, Plinko Neon, Pinball Arena, and Galaxy Spin. Each map follows a dramatic 4-act narrative structure with different obstacles — spinning bars, bouncy bumpers, diamond pegs, and split paths — for completely different racing experiences.

Yes! Roulette Rush is fully responsive and works on smartphones, tablets, and desktop computers. The interface adapts to your screen size automatically with optimized touch controls, a collapsible panel for maximum viewing area, and HiDPI rendering for crisp visuals on retina displays.

Yes, during a race you can switch between 1x (normal), 2x (fast), and 3x (fastest) speed. This is useful for speeding through longer races with many marbles or keeping the normal pace for dramatic moments on stream.

Adding *N after a name creates N marbles for that entry. For example, "Bob*5" creates 5 marbles all named Bob, giving Bob a 5x higher chance of winning compared to someone with just 1 marble. This is perfect for subscriber-weighted giveaways or giving certain entries more chances.

No! Roulette Rush requires no sign-up, no login, no registration, and no download. Just visit the website and start using it immediately. It's completely free with no hidden costs or premium tiers.

Yes! Roulette Rush is free to use for both personal and commercial purposes. Use it in your YouTube videos, Twitch streams, business meetings, company events, classroom activities, or any other context without restrictions.

After a race finishes, the full rankings are displayed in the sidebar. You can take a screenshot or screen record the race to share with your audience or participants. On stream, your viewers will see everything in real-time.

Occasionally, marbles may slow down or get temporarily stuck on obstacles. The game has built-in anti-stuck mechanics that automatically detect stuck marbles and teleport them forward. Escalating teleport distances (150px → 250px → 400px+) ensure no marble stays stuck for long.

Roulette Rush is a marble roulette-style game with a space/neon aesthetic similar to space roulette games. If you're looking for a marble roulette or space roulette experience, Roulette Rush delivers exactly that — physics-based marble racing through neon-themed obstacle courses. It combines the marble roulette concept with a practical random name picker.

Yes! Roulette Rush is fully open source on GitHub. You can view the code, report bugs, request features, or fork the project to customize it for your needs. Contributions are welcome.

The best free random name picker depends on your needs. For entertainment and audience engagement, Roulette Rush is the top choice — it uses physics-based marble racing instead of a boring wheel. For a simple wheel spinner, Wheel of Names works well. For chat-based picking on Twitch, StreamElements has a built-in giveaway feature. Roulette Rush stands out because it requires no sign-up, supports up to 500 names, and makes every selection exciting to watch.

A fair random name picker uses a genuinely unpredictable method to select winners. Basic tools use Math.random(), which is pseudorandom. Roulette Rush goes further by using a real physics engine (Matter.js) where every bounce, collision, and roll affects the outcome. This means the result depends on thousands of physics calculations rather than a single random number, making it both fair and transparent — everyone can watch the marble race happen in real-time.

To pick a giveaway winner: 1) Collect participant names, 2) Paste them into a random picker tool, 3) Run the selection. With Roulette Rush, you paste names into the text area, choose a map, and start a marble race. The first marble to cross the finish line wins. For weighted giveaways (e.g., subscribers get more chances), use the name*count syntax like 'Alice*3' to give Alice 3 entries. It's the most engaging way to pick winners on Twitch or YouTube streams.

Using a random name picker in the classroom is simple: 1) Open Roulette Rush on your computer or projector, 2) Enter student names (one per line or comma-separated), 3) Click Start Race and let students watch the marble race. Students love it because it turns routine name-picking into an exciting event. No account needed — just open the website and go. Works on classroom projectors, tablets, and phones.

The best random name generators for teachers are: 1) Roulette Rush — most engaging, physics-based marble racing that students love, 2) Wheel of Names — classic wheel spinner, simple and familiar, 3) Flippity — integrates with Google Sheets for easy roster management, 4) ClassDojo — built into the ClassDojo ecosystem. Roulette Rush is the top choice for student engagement because the marble racing format turns name-picking into a game.

Wheel of Names uses a random number generator (RNG) to determine the result the moment you click 'spin' — the spinning animation is purely cosmetic. It's pseudorandom, which is fair enough for most purposes. Roulette Rush takes a different approach: instead of RNG, it uses real physics simulation where every marble bounce and collision determines the winner. This makes the randomness visible and transparent — you can watch the physics play out in real-time.

To do a random draw online: 1) Go to Roulette Rush (no sign-up needed), 2) Enter participant names in the text area, 3) Select a map, 4) Click Start Race. The marble race determines the winner through real physics simulation. You can run it live on a video call, stream, or projector for full transparency. For weighted draws, use name*count syntax (e.g., 'Bob*5' gives Bob 5 entries). Speed controls (1x/2x/3x) let you adjust the pace.
