Marble Roulette
Named marbles tumble through pegs, spinning bars, funnels, and a roller-coaster course to decide the ranking. Watching is half the fun.
Type in names, drop the marbles, and let physics decide! The marbles tumble down a random obstacle course full of pegs, spinning bars and ramps — the finish order picks your winner (or the unlucky last place).
One name per line, or separated by commas. Add *N after a name to give it N marbles (better odds). 2–30 marbles in total.
The first marble to reach the goal wins.
OgleOgle Marble Roulette is a free random picker where marbles labeled with participant names tumble through a 2D physics engine — complete with gravity, friction, and collisions — falling down a course of pegs, spinning bars, funnels, and a roller-coaster track to decide a ranking. Where a plain roulette wheel or ladder game only shows you the result, the marble roulette turns the picking process itself into a 30-60 second mini broadcast, making it the most popular drawing tool at dinners, birthdays, and live streams.
When should you use it? Picking the MC at a team dinner or retreat, running viewer giveaways on YouTube or Twitch livestreams, drawing door prizes at year-end parties, mini-games at birthday parties, deciding "who presents first?" in a group chat with built-in suspense, or inserting random picks into video content — anywhere the journey to the answer matters more than the answer itself.
Key features. (1) Type names to assign one marble to each participant. (2) Weight option to triple, quintuple, etc. a name's marble count (e.g. enter "Name*3"). (3) First-place mode (last marble standing). (4) Last-place mode (first marble eliminated — perfect for penalties). (5) Peg, spinning bar, and funnel course. (6) Roller-coaster course (track-style layout). (7) A new randomized course every run. (8) Live ranking board. (9) Capture and share the result screen.
FAQ. Q. How do weights work? A. Append "*3" or "*5" to a name and that many extra marbles get added, raising their win odds proportionally. Q. Is the simulation actually random? A. Yes — every run uses a fresh seed and randomized starting positions, so identical outcomes almost never repeat. Q. Is it OK for livestream giveaways? A. Absolutely — broadcasting the simulation makes the fairness visible and is ideal for live draws.
