How to Use This Calculator
1. Enter your options in the 'Wheel Entries' field, placing each option on its own line. You can add anywhere from 2 to 50 entries. 2. Choose a spin duration that suits your style — Fast, Normal, Slow, or Extra Slow. 3. Decide whether the winning entry should be removed after each spin, which is useful for picking multiple unique winners. 4. Set the number of times you want to spin if you need to select more than one result. 5. Click the 'Calculate' or 'Spin' button and instantly see your randomly selected winner or list of winners displayed in the results section.
How the Random Wheel Spinner Works
The random wheel spinner simulates a physical prize wheel by assigning each entry an equal slice of the wheel. When you spin, the tool selects a winner using JavaScript's Math.random() function, which generates a pseudo-random floating-point number between 0 and 1. This number is then mapped to one of your entries, giving every option an equal chance of being selected.
Equal Probability for Every Entry
If you enter N items on the wheel, each item has a probability of:
- 1 / N × 100% chance of being selected each spin
- For example, with 5 entries, each has a 20% chance
- With 10 entries, each has a 10% chance
Remove Winner Mode
When 'Remove Winner After Spin' is enabled, the winning entry is taken out of the pool before the next spin. This is ideal for raffle draws or assigning unique tasks — it ensures no one is picked twice. The remaining entries count updates after each spin to reflect the new pool size.
Multiple Spins
Setting the spin count higher than 1 lets you pick multiple winners in one go. The tool spins the wheel the specified number of times and lists all results. Combined with the remove-winner feature, this is a powerful way to run a full raffle draw instantly.
Fairness and Randomness
The selection algorithm does not favor any position or entry. Each call to Math.random() is independent of the previous one, so past results do not influence future spins. This mirrors the statistical fairness of a well-balanced physical wheel.
