Yes or No Wheel

1. Press Spin the wheel for a fair 50/50 yes or no answer.
2. Open Options to enable custom odds if you need a different probability than 50%.
3. Watch the answer and check the totals and percentages below the wheel.
4. Review previous spins in the spin history, and clear it whenever you want.

In default mode the wheel uses a secure random integer that resolves to yes or no with equal probability. The decision is made before any rotation begins, and the animation simply travels to the matching half of the wheel. When custom odds are enabled, the tool uses weighted selection: a yes probability of 75% means yes is selected three times as often as no over many spins.

The label above the wheel always states the active mode. Fair 50/50 appears only when the odds are exactly balanced; as soon as custom odds are switched on, the label changes to Custom Odds and shows both percentages so the bias is never hidden.
