Spin the Wheel

Add your names or items, spin the wheel, and let a fair random pick decide.

About the spinner wheel

This spinner wheel picks a fair winner using the browser's cryptographically secure random number generator, then animates the wheel to land exactly on that result. Add names for choosing a person, or items for decisions like what to eat or which task to start first.

Enable "remove winner" to run an elimination draw, where each spin removes the winning entry so everyone or everything gets picked exactly once over multiple spins.

How does a random spinner wheel pick a winner?

A random spinner wheel first picks a winning entry using the browser's cryptographically secure random number generator, giving every entry an equal 1/N chance, then animates the wheel to spin and land exactly on that pre-selected slice. Example: with 5 items, each one has a 20% (1/5) chance per spin.

Steps to use the spinner wheel

  1. Add or edit the list of names or items you want to choose from.
  2. Remove any placeholder entries you don't need, or add more with the add button.
  3. Optionally enable "remove winner" for elimination-style draws across multiple spins.
  4. Click spin — the result is determined instantly, then the wheel animates to land on it.
  5. Read the winner shown below the wheel once the animation finishes.

Spinner probability formula

P(any single item winning) = 1 / N
  • N = the total number of items currently on the wheel
  • Equal chance = every slice has the same probability, regardless of its visual size on the wheel

Frequently asked questions

Is the wheel's landing position determined before or after it starts spinning?

Before. The winner is selected first using a fair random draw, and then the animation is calculated backward to make the wheel visually land on that exact result — this way the spin looks natural while guaranteeing the outcome was decided fairly, not influenced by animation timing.

Does a longer or shorter spin change the odds?

No. The spin duration and number of rotations are purely visual — they don't affect which entry was already selected as the winner. Every entry has the same 1/N probability regardless of how long or dramatic the animation looks.

What does "remove winner" do exactly?

When enabled, the winning entry is deleted from the wheel immediately after each spin, so it can't be picked again. Spinning repeatedly with this enabled works like drawing names out of a hat one at a time — useful for assigning turns or making sure everyone gets picked exactly once.

Can I use this for weighted odds, like giving one item a higher chance?

Not directly — every item on the wheel has an equal chance by default. To simulate weighted odds, add the same item multiple times (for example, listing "Pizza" three times gives it three times the chance of an item listed once).

The wheel gives every current entry an equal, fair chance per spin; if you need certain outcomes weighted higher or lower, adjust the count of duplicate entries rather than expecting the tool to weight them automatically.
