A result you can inspect
Fair draws save their exact inputs and result in a tamper-evident audit. Open a verification link or download the proof instead of relying on the animation alone.

Step right up.
Leave it to chance.
Spin the carousel, roll the dice, flip a coin, or pick a name from the crowd. Randomize Fun uses browser cryptography to make every choice fair—and gives you the proof to show for it.

Put the options in, give the wheel a whirl, and share a proof-backed winner.
02 / PRIZE BOOTHThe fair picker
Pick a name without bias, with CSV imports and transparent weights.
03 / TEAM TENTTeam picker

Roll a physical 3D die with browser-secured randomness.
05 / FLIP BOOTHThe coin flip
Call it in the air. Keep a clear audit trail on the landing.
06 / LUCKY DRAWLucky numbers
Draw numbers from a range, with exclusions and batch picks.
07 / TICKET CHECKProof checker
Check a saved draw and see whether its audit payload changed.
Your first visit / start here
Three steps to a little magic.
Fill the ticket box
Type one entry per line, or switch on comma splitting for a pasted list. Repeats stay in the draw; total and unique counts help you check your list.
Choose your kind of fun
Use Fair Draw for a cryptographic selection with an audit record. Choose a playground when you want your swipe or toss to influence the outcome.
Reveal it. Then check it.
Celebrate the result, download its proof, or invite an audience to watch any fair generator live. A saved proof lets others check whether the recorded payload has changed.
The Randomize Fun experience
More than a spin.
A whole midway.
Bring the crowd along
Host a live fair wheel with read-only audiences, or use the picker for weighted entries and certificate exports. Repeats stay in your list, just as you entered them.
See the tool guides →Hands-on, when you want it
Inspect anime coin and dice faces in 3D. Switch to a separate playground for movement-driven outcomes. Fair Draw stays independent of your gestures.

01 / CLASSROOM
A classroom full of possibilities
Choose a discussion starter, topic or team activity. Use equal entries when every option should have the same chance.

The information booth
Good questions. Clear answers.
What is Randomize Fun?
An anime-inspired collection of random decision tools: a wheel, weighted name picker, random team picker, a 3D six-sided die, coin flipper, number generator and proof checker. You can start using the tools without creating an account.
Is Fair Draw really random?
Fair Draw uses the browser's crypto.getRandomValues() source with rejection sampling, rather than choosing a result from animation timing. The result is selected before the animation presents it. Each occurrence on the wheel has the same chance; picker rows can have different disclosed weights.
Do repeated names stay in my list?
Yes. Every occurrence stays in order as a separate entry. Alice, Alice, Bob gives Alice two of the three wheel slots. The total includes repeats; the unique counter ignores letter case. Both wheel and picker allow up to 5,000 entries, including repeats.
Why can the same winner appear twice?
Fair draws do not automatically remove winners. With an unchanged list, each new draw is independent, so repeats are normal. If your rules require no repeat winners, edit the wheel or picker list before the next draw. The number generator has a separate without-replacement option for a single batch.
Can dragging change the result?
In Fair Draw, dragging only changes your view of the 3D object, not the odds or saved result. In Physics Playground and Gesture Playground, your movement can change the landing. Playground outcomes are not cryptographically fair and do not create proofs or broadcast live results.
How do I share a draw with an audience?
On any generator in Fair Draw—wheel, picker, coin, dice, numbers or teams—choose Host room and share the audience link, QR code or room code. Only the host edits and draws; audience members receive the settings and every result. Network timing is best-effort. For a completed fair draw, use Verify latest or Download proof in the audit panel. The picker also offers PDF and PNG certificates when its verification link is short enough.
What does a matching proof actually prove?
The proof checker recomputes SHA-256 over the saved entries, weights, result, random bytes and other audit fields. A match detects changes to that saved payload. It does not establish that a host committed the inputs before drawing, prevent someone from discarding draws, or guarantee compliance with giveaway rules.
Where do my entries go?
Generator sessions and recent fair-draw history are stored in this browser's local storage. Live rooms send shared entries and audited results to the room service. Proof links and downloaded certificates can contain your full entry list, so share them carefully. Read the About page's data overview before using personal or confidential information.
Can I use it without 3D motion?
Yes. Fair coin and dice draws show a static result when reduced motion is enabled, and the fair wheel settles without its normal spin. Fair results remain available when WebGL is unavailable. The optional physics playground needs WebGL and motion to simulate a toss.
Why do I see ad placement previews?
A labeled preview shows where an advertisement could appear; it is not a live ad and makes no advertising request. When live advertising is enabled, the site offers advertising preferences. Post-result placements stay separate from controls and do not automatically refresh after every draw. Occasionally, after a completed draw, Google may show a full-screen ad break; it never appears during a draw or in your first two uses, and visitors who decline advertising never see it.
