Yes or No Generator
Stuck on a small decision? The Yes/No tab gives you a random YES or NO with one click. Each answer has exactly a 50% chance, drawn from your browser's crypto.getRandomValues, so neither answer is favored and earlier results don't affect the next one. A running tally shows how many yeses and noes you have had.
- Think of a question that can be answered yes or no.
- Click the circle or Decide! to get your answer.
- Ask again as often as you like. Best of three is a good tie-breaker.
It works well for low-stakes choices such as "Should I order pizza?" or "Go to the gym today?", and for party games and classroom picks. You can bookmark or share it directly: www.njhouse.kr/tools/random-tools#yes-or-no. Prefer a spinning wheel to watch? Try the Yes or No Wheel.
Frequently Asked Questions
Is the coin flip truly random?↓
Yes. The coin flip uses the browser's built-in crypto.getRandomValues API, which provides cryptographically secure random numbers. Each flip has an exactly 50/50 chance of landing on heads or tails, with no bias.
What does d20 mean in dice?↓
d20 refers to a 20-sided die. The 'd' stands for 'die' or 'dice', and the number after it is the number of sides. Common types: d4 (4-sided tetrahedron), d6 (standard 6-sided cube), d8, d10, d12, d20, and d100 (percentile die). These are commonly used in tabletop role-playing games like Dungeons & Dragons.
How do I pick a random name from a list?↓
Go to the 'Random Picker' tab, enter the names in the text box (one per line or separated by commas), then click 'Pick 1 item'. For a class lottery or raffle, turn on 'Remove after picking' to ensure each name is only selected once.
How does the yes or no generator work?↓
Open the Yes/No tab (or go straight to www.njhouse.kr/tools/random-tools#yes-or-no), think of a yes-or-no question, and click Decide!. The answer is picked with crypto.getRandomValues, so YES and NO each have exactly a 50% chance and every answer is independent of the previous one.
Is there a yes or no wheel I can spin?↓
Yes. If you'd rather watch a wheel spin than click a button, use the Yes or No Wheel at www.njhouse.kr/tools/spin-wheel/yes-or-no. It gives the same fair 50/50 result with a spinning animation.
Should I let a yes or no generator make real decisions?↓
Use it for low-stakes choices, tie-breakers, and games. For important decisions it works best as a gut check: if the answer you get disappoints or relieves you, that reaction usually tells you what you actually want.
