Perguntas frequentes
How do I set a weight?
Add it after the item name with an x, comma, or colon — for example "Grand prize x1", "Carla, 5", or "Bob: 0.5". An item with no weight is treated as 1.
Does a higher weight mean more likely?
Yes. An item with weight 3 is three times as likely to be picked as one with weight 1.
Are the odds actually fair?
Yes. The pick is driven by your browser's Web Crypto randomness, so the long-run frequencies match the weights you set with no hidden bias.
Is my list of entries private?
Completely. Everything runs in your browser, and your items and weights are never uploaded anywhere.
