Create a weighted wheel spinner when your choices should not all have the same chance. Give every name, prize, task, or outcome a relative weight and the wheel calculates the probability automatically. Wider slices make the custom odds visible before anyone spins, while weight 0 can keep an entry in the list but temporarily off the wheel. Free to use with no signup.
How weighted wheel probability is calculated
A weighted spinner treats each number as a relative share, not automatically as a percentage. The probability for one entry is its positive weight divided by the sum of every positive weight on the wheel. For example, entries weighted 10, 6, 3, and 1 have a total weight of 20. Their selection chances are therefore 50%, 30%, 15%, and 5%. Multiplying all four numbers by the same amount would not change the odds, which is why simple ratios work as well as percentages. The starter wheel uses exactly that distribution, and each quick-load preset supplies its own real weights. Edit the number beside any entry and both its percentage badge and visible slice size update. Set a weight to zero when an option should remain saved but must not be selected. Decimal weights are supported when a finer split is useful. Pressing SPIN makes one random selection from the configured distribution before the animation begins; the movement reveals the selected result rather than changing it. Auto-remove Winner can then take that result out and recalculate the distribution among the remaining entries. Weighted wheels are useful for prize rarity, probability lessons, game encounters, priority-based task picking, simulations, and any draw where equal chances would misrepresent the rules.

- 1
Add your possible outcomes
Type choices one at a time, paste a full list in Bulk Edit, or load one of the weighted examples. Each row is one possible result.
- 2
Assign relative weights
Edit the number beside each entry. A weight of 6 is twice as likely as 3; the numbers do not need to add to 100 because the wheel converts them into percentages for you.
- 3
Check the slices and spin
The slice sizes and percentage badges show the configured odds. Press SPIN and the result is selected from that weighted distribution before the animation reveals it.
When custom probability is useful
🎲 Game loot and encounters
Model common, uncommon, rare, and legendary outcomes for tabletop sessions, game prototypes, challenges, or community streams.
📚 Teaching probability
Show how relative weights turn into percentages, run repeated trials, and compare observed results with the expected distribution.
📋 Weighted task selection
Give urgent or valuable tasks a higher chance while leaving lower-priority work available. A spin breaks the tie without pretending priorities are equal.
🧪 Scenario sampling
Sample likely and unlikely test cases, role-play events, writing prompts, or workshop scenarios in proportions that match your exercise.
📊 Allocation demonstrations
Visualise splits such as 70/20/10 or 50/30/15/5 with labelled slices. It is a simple way to explain a distribution to a group.
Weighted Wheel Spinner — Frequently Asked Questions
What does a weight mean on the spinner wheel?
A weight is a relative share of the total. If one entry has weight 3 and another has weight 1, the first is three times as likely to be selected. Their probabilities are 75% and 25% because the total weight is 4.
Does a weight of 10 mean a 10% chance?
Only when all active weights add up to 100. The wheel divides each entry weight by the total of all positive weights. For weights 10, 6, 3, and 1, the total is 20, so the chances are 50%, 30%, 15%, and 5%.
How do I change the odds?
Edit the weight field beside an entry in the Entries tab. Higher values increase that entry’s chance and slice size; lower positive values reduce them. Percentage badges update from the complete list automatically.
Can I use decimal weights?
Yes. Weights can use up to two decimal places, so values such as 0.5, 1.25, and 2 are valid. Ratios matter more than scale: 0.5 and 1 produce the same 1-to-2 split as 5 and 10.
What happens when an entry has weight 0?
It stays in the entries list but is inactive: it has no slice and cannot be selected. This is useful when you want to pause an option temporarily without deleting it and adding it again later.
Are weighted spins still random?
Yes. Random does not have to mean equal. The configured weights define each entry’s chance, then a random selection is made from that distribution before the animation starts. Entries with the same positive weight remain equally likely.
Can I paste or import a weighted list?
Yes. In Bulk Edit, add a suffix such as “Grand Prize::1” or “Try Again::8” to a line. You can also import a CSV with name and weight columns, then export it again without losing the custom values.
Can a weighted winner be removed after each spin?
Yes. Turn on Auto-remove Winner in Options when you need sampling without replacement. Once an entry wins it leaves the active list, and the wheel recalculates the remaining probabilities for the next spin.
About the Weighted Wheel Spinner
The Weighted Wheel Spinner is built for choices with unequal probability. Each positive weight contributes that many relative shares to the draw, so you can describe odds with small ratios, whole percentages, or decimal values. The wheel calculates and displays the resulting percentages rather than requiring you to do the arithmetic.
The sample wheel opens at 50%, 30%, 15%, and 5%, so its probability settings are real from the first spin. Selection happens before the animation, and the animation reveals that weighted result. Your wheel remains in this browser by default unless you deliberately create a share or embed link.
