Weighted Decision Wheel — Spin with Adjustable Percentages
Set your own percentages, add your options, spin — the free weighted decision wheel with fully adjustable probabilities. Useful when some choices should be more likely than others. No sign-up.
Weights In, Segments Out
A Weighted Decision Wheel is a free online tool that lets you assign custom probabilities to multiple options before spinning. It works as a probability wheel: you set weights and the wheel picks based on those odds. Unlike a standard Yes No Wheel with equal 50/50 odds, a decision wheel with weights lets you set different weights (1-100) for each choice, reflecting your preferences. Options with higher weights have larger segments and higher chances of being selected. It is ideal for complex decisions where some options matter more than others.
- Job offer Aweight 65 of 100 → 65%65%
- Job offer Bweight 35 of 100 → 35%35%
Two job offers weighted 65 and 35 (adding up to 100) split the wheel 65% to 35% — a visible lean toward Job offer A while still leaving real odds for B, unlike a flat 50/50 wheel.
Setting Weights That Match a Real Lean
To use it, start by adding your decision options. You can add as many as you need, with a minimum of two required. Then assign a weight to each option using the slider or input field. Weights range from 1 to 100, and higher weights mean a higher probability of being selected. The tool automatically converts weights to percentages, so you can see exactly how likely each option is to be chosen.
Weights you set
- Job offer A
- 65
- Job offer B
- 35
The math
- Sum: 65 + 35 = 100
- Each weight ÷ total = that option's share
Odds shown
- Job offer A
- 65%
- Job offer B
- 35%
Once you've set your weights, click "Spin the Wheel" and watch it rotate. Options with higher weights appear as larger segments, so the visual matches the actual odds.
Weighted Decision Wheel vs. a Flat 50/50
Understanding the differences between weighted and equal-odds decision wheels helps you choose the right tool for your needs. A Yes No Wheel gives exactly 50% probability to each option; a Weighted Decision Wheel allows you to set custom probabilities, so you might give 65% to one option and 35% to another instead.
| What differs | Yes No Wheel | Weighted Decision Wheel |
|---|---|---|
| Odds | Exactly 50%, fixed | Any split you set, e.g. 65/35 |
| Fits when | Both options are truly equal | You lean toward one but still want randomness |
| Setup step | None | Set a weight per option first |
Decisions Where a Lean Deserves to Show
Weighted lean
Career decisions
When choosing between job offers or career paths, you might prefer one option slightly more but want help making the final decision. A weighted decision wheel lets you express that preference while still getting assistance.Weighted lean
Relationship decisions
When you lean one way more than the other on a relationship choice, a weighted wheel lets you express that lean instead of forcing a coin-flip-style even split.Multi-option
Project prioritization
When you have multiple projects or tasks and some are more important than others, weighted decision wheels help you prioritize while still introducing an element of randomness.Self-check
Testing your true preferences
Sometimes setting weights helps you realize your actual preferences. If you find yourself wanting to adjust weights after seeing the result, that's valuable information about your true feelings.
Getting Honest Results From the Weights
- Be Honest About Your Preferences: Set weights based on your true feelings, not what you think you should prefer. The wheel works best when weights reflect your actual leanings.
- Use Weight Differences Meaningfully: Small weight differences (like 45 vs 55) create subtle probability differences. Larger differences (like 20 vs 80) create significant probability gaps. Choose weight differences that match how strongly you prefer one option over another.
- Consider Multiple Factors: When setting weights, think about importance, feasibility, risk, and your gut feelings, and combine all of that into a single number per option.
- Pay Attention to Your Reaction: Notice how you feel when you see the result. If you're disappointed or relieved, that reveals your true preferences — sometimes more valuable than the decision itself.
- Adjust and Reconsider: If the result doesn't feel right, you can adjust weights and spin again. The process of adjusting weights often helps clarify your preferences.
Don't want to take the odds on faith? Open "Simulate & Calculate Odds" below the wheel to run 10, 100, 1,000, or a custom number of spins instantly (no animation) and compare the observed results to the expected percentages side by side, with a CSV export for the numbers.

How Your Weights Turn Into Odds
Each spin runs the same process: your browser generates a random number using JavaScript's built-in Math.random(), that number is checked against the probability ranges your weights define, the matching option is selected, and the wheel animates a rotation that lands on it. The animation is purely cosmetic — the result is already decided the instant you click Spin. Math.random() is suitable for personal decisions and entertainment, but it is not cryptographically secure or independently audited; see our Randomness & Fairness Audit for the full technical breakdown.
Weights and Probabilities, Answered
A Weighted Decision Wheel is a decision-making tool that allows you to assign different probabilities (weights) to your options. Unlike regular decision wheels where all options have equal chances, weighted wheels let you express preferences while still getting help with difficult choices.
