PickerToolbox's yes/no wheel spins and lands on a random yes or no answer. Unlike a simple coin flip, the bias slider lets you weight the outcome — slide it towards Yes to make a yes result more likely, or towards No for the opposite. At the default position, each result has exactly a 50% probability. All randomness uses crypto.getRandomValues().

How to use the yes/no wheel
Click the wheel or the Spin button to get a result. The wheel spins and decelerates naturally before landing on yes or no. To adjust the probability, drag the bias slider: moving it left increases the chance of yes, moving it right increases the chance of no. The current split is displayed as a percentage next to the slider. Press Space to spin without using the mouse.
When to use a yes/no wheel
A yes/no wheel is the right tool when you have exactly two outcomes and want the visual drama of a spinning wheel rather than a simple coin flip. Common uses:
- Making decisions when you are genuinely undecided between two options
- Games — randomising yes/no choices in party games or quizzes
- Teaching probability — demonstrating how changing the bias affects the distribution of outcomes over many spins
- Live streams — letting your audience watch the wheel spin before an outcome is revealed
- Weighted decisions — when you want to allow yes more often than no (or vice versa)
Yes/no wheel vs. coin flip — which to use?
A coin flip is always exactly 50/50 and is the simplest possible binary random decision. Use it when you want pure equal-probability randomness and don't need visual appeal.
The yes/no wheel offers two things a coin flip does not: a visual spinning animation that is more engaging for an audience, and an adjustable bias. If you want to make one outcome slightly more or less likely — for instance, a 70% chance of yes and 30% chance of no — the yes/no wheel handles this directly. A coin flip cannot.
Understanding the bias setting
The bias slider sets the proportion of the wheel occupied by each segment. At 50%, each segment is exactly half the wheel. At 70% yes, the yes segment takes up 70% of the wheel's area, making it 2.33× more likely to be landed on than the no segment. The underlying randomness is still cryptographically secure — the bias changes the size of the segments, not the fairness of the spin.
This is identical to the weighted segments in the PickerToolbox wheel spinner, where you can assign custom weights to any number of options. The yes/no wheel is a simplified version optimised for binary decisions.
Need more than two options? The full PickerToolbox wheel spinner supports unlimited options with custom weights, colours, and eliminate mode.
Open PickerToolboxFrequently asked questions
Is the yes no wheel truly random?
Yes. PickerToolbox uses window.crypto.getRandomValues(), the Web Cryptography API, for all random selections. With a 50/50 split, each spin has exactly equal probability of landing on yes or no.
Can I make yes more likely than no?
Yes. Use the bias slider to adjust the probability. Moving it towards Yes gives yes a higher probability; moving it towards No does the opposite. The current split is shown as a percentage.
What is the difference between a yes/no wheel and a coin flip?
A coin flip is always exactly 50/50. The yes/no wheel lets you set a custom bias, making one outcome more likely than the other. Use the coin flip for a pure 50/50 decision, and the yes/no wheel when you want to weight the outcome or want a visual spinning animation.
Does the yes no wheel work on mobile?
Yes. The yes no wheel is fully responsive and works on all modern smartphones and tablets. Tap the wheel or the Spin button to get a result.
Can I get more than yes or no?
For decisions with more than two outcomes, use the PickerToolbox wheel spinner, which supports any number of options with custom weights.
