📖 Frequently Asked Questions
The Decision Roulette Wheel is a free online tool that helps you make random decisions by spinning a customizable wheel. Simply add your options, click SPIN, and let the wheel decide for you! Perfect for choosing restaurants, weekend activities, or settling friendly debates.
You can easily customize options by: (1) typing in the input field and clicking the button, (2) clicking the Batch Edit button to paste multiple options (one per line), (3) using one of our preset templates like "Dinner" or "Yes/No/Maybe", or (4) clicking the icon on any option tag to remove it.
Yes! The wheel uses a cryptographically secure random number generator (via
crypto.getRandomValues) to determine the final stopping position. Combined with a variable spin duration and rotation count (5-8 full rotations plus a random offset), each outcome is genuinely unpredictable and fair.
Absolutely! The Decision Roulette Wheel is fully responsive and works beautifully on smartphones and tablets. The wheel automatically resizes to fit your screen, and all controls remain easily accessible with touch-friendly buttons. No app download required – just open in your mobile browser.
The wheel features realistic tick-tick spinning sounds that slow down as the wheel decelerates, plus a celebratory chime when the result is revealed. You can easily toggle sound on/off by clicking the speaker icon next to the SPIN button. Sound is generated using the Web Audio API with no external files needed.
You can add between 2 and 20 options to the wheel. With 2 options, it works like a coin flip. With 20 options, you get a colorful multi-segment wheel. For best visual results, we recommend 4-12 options. The font size automatically adjusts to keep all labels readable.
