pick-random-item
Picking a random item from a list is the simplest random task β drawing a winner, choosing a meal from a list of options, picking a movie for movie night. The ZTools Pick Random Item tool runs in the browser using fair pseudo-random selection (Math.random) or cryptographic randomness (crypto.getRandomValues for prize draws). Supports picking N items without replacement (no duplicates) or with replacement, and optional per-item weights for biased draws.
Use casesβ
Pick a winner from a listβ
Paste 200 entrants, pick 1. With crypto-RNG for auditable fairness.
Decide between optionsβ
List of restaurants for tonight; pick one randomly. Removes decision fatigue.
Run a draw with multiple winnersβ
"Pick 3 from 100" β without replacement, each winner unique.
Weighted random for unequal probabilitiesβ
Some entries get more entries (one-per-purchase). Provide weights β tool draws proportionally.
How it worksβ
- Paste list β One item per line (or comma-separated, JSON).
- Pick count β How many to draw. With or without replacement.
- Optional weights β Each item can have a weight (default 1). Higher weight = more likely.
- Pick RNG β Math.random (fast, fine for casual) or crypto.getRandomValues (cryptographically random).
- Draw β Output: chosen item(s). Re-draw for new pick.
Examplesβ
Input: [A, B, C, D, E], pick 1
Output: One random β say "C". Each equally likely (20%).
Input: Same list, pick 3 without replacement
Output: E.g. [B, D, A] β three unique items.
Input: Weighted: A weight 1, B weight 3, C weight 1
Output: A and C each ~20%, B ~60%.
Frequently asked questionsβ
How is this different from list-randomizer?
List-randomizer outputs a full shuffled list. Pick-random-item outputs N selected items. Both use Fisher-Yates internally for fairness.
Without replacement?
Once picked, an item won't be picked again in the same draw. With replacement: same item can repeat.
Weighted draw?
Useful for biased random β e.g. one ticket vs three tickets per entrant. Weights need not sum to a specific value.
Privacy?
All in browser.
Tipsβ
- For raffles, use crypto-RNG β auditable as fair.
- For decision-making (lunch, movies), Math.random is fine.
- For weighted random, document the weights β transparency aids fairness perception.
- For "pick all in random order", use list-randomizer instead β full shuffle is more efficient.
