Decision Dice

About Decision Dice

A coin flip treats every choice as 50/50 — but real decisions rarely feel that way. You mostly want pizza, you're slightly tempted by the gym, and someone at the table keeps saying "sushi" with no conviction whatsoever. Decision Dice lets the odds match reality: give every option a weight, see the exact percentages, and roll. The die tumbles, lands, and the decision is made — by chance, but chance you tuned.

How it works

• Add options and weights. Weight is how many "sides of the die" each option occupies: pizza 3 / tacos 2 / salad 1 makes a six-sided die where pizza covers three faces (50%), tacos two (33%), salad one (17%). The exact chance for each row updates live.
• Roll. A single tap gives you a tumbling roll with sound and confetti for the winner. Or run ×10 / ×100 rolls instantly when you're settling something in bulk.
• Watch the fairness. The stats panel tallies every roll and draws each option's observed share against a tick mark at its expected odds. Roll enough and the bars converge on the ticks — the law of large numbers, live on your screen.
• Bench without deleting. Set any option's weight to 0 and it sits out of the roll while staying on your list.

Honest randomness

Every roll draws from your browser's crypto.getRandomValues — the cryptographically secure random generator, the same source used for encryption keys — and maps it across the weights. No seed tricks, no house edge, no server that could nudge results: the entire roll happens on your device, and the stats panel exists so you can verify the distribution yourself instead of taking our word for it.

Things people roll for

• Dinner, movie night, and "whose turn is it" — with vetoes expressed as low weights instead of arguments.
• Chore assignment where the person who did it last week gets a lower weight this week.
• Weighted giveaways — one entry per ticket, exactly as many "sides" as each person earned.
• Game night house rules: custom dice with any number of faces (the Classic 1–6 preset is just six equal weights).
• Breaking your own decision paralysis: give the sensible option 4, the fun option 1 — and notice how you feel when the fun one hits. That feeling is your real answer.

Weighted vs. equal odds — which tool?

If every option should have the same chance and you want the spinning-wheel drama — picking a raffle winner, choosing a student — our Name Selector wheel is built exactly for that, with elimination mode and draw history. Decision Dice is the one you want the moment the odds shouldn't be equal.

Common questions

How do I make a random decision with unequal odds?

Add your options and give each a weight: pizza 3, tacos 2, salad 1. The tool shows each option's exact percentage and the animated roll respects those odds precisely.

Is the dice roll actually random and fair?

Yes, verifiably. Rolls draw from your browser's cryptographically secure random generator, the same source used for encryption keys, and the stats panel plots observed results against expected odds so skeptics can watch a few hundred rolls converge.

What is this better at than a coin flip or spinner wheel?

Weights. A coin and a wheel treat every option equally; real decisions rarely are. When you mostly want pizza but want to leave room for surprise, weighted dice model that honestly.

Can I roll many times at once?

Yes. Roll one at a time with sound and confetti, or in bulk (x10, x100) when you need many decisions or want to stress-test the odds.

Do my options get saved or sent anywhere?

Options and roll history are remembered locally in your browser only, and nothing is uploaded. Reset wipes the stats whenever you want a fresh start.
