Random Name Picker - Fair Draws from a List

The Random Name Picker selects one or more entries from a pasted list for classroom cold calls, giveaways, or simple team picks. Enter names one per line or separated by commas, set how many to pick, and choose unique picks or allowed repeats. Unique mode shuffles with Fisher-Yates and crypto.getRandomValues, then returns the top names. Generation stays in the browser.

Pick a random name from a list

Paste at least one non-empty name into the names field. Default sample text shows four placeholder names so the control is never blank on first load. Replace that sample with the real roster before drawing. Count defaults to 1 for a single winner. The Random Name Picker trims whitespace and drops empty tokens after splitting on newlines or commas.

Press pick to fill the result list. Duplicate lines in the pasted text count as separate entries, so two identical spellings can both appear in the pool. Clean the list first if each person should appear once. Comma-separated and line-separated formats can mix in one paste; both splitters run on the raw string.

Remove names after picking

Unique picks set to Yes draws without replacement from the current list. The engine copies the roster, shuffles it, returns the first count names, and can expose the remaining names after the cut. Count cannot exceed the number of parsed names; an oversized unique request returns an error instead of recycling names.

Allow repeats (unique No) draws each pick independently from the full list, so the same person can win more than once in one batch. Use unique Yes for raffles and fair classroom turns. Use repeats when a simulation should ignore who was already chosen. The Random Name Picker states the mode in the select label so the rule is visible before the draw.

Pick winners for a giveaway or classroom draw

For a giveaway, paste entrants, set count to the number of prizes, keep unique Yes, and draw once. Announce the printed order as first prize, second prize, and so on if rank matters. For a cold call, keep count at 1 and draw when a new volunteer is needed. Clearing and repasting resets the pool for the next period.

Team-style splits work by drawing unique names in batches equal to team size, then assigning each batch to a team label offline. The page does not auto-balance teams or name groups; it only returns the picked slice. Remaining names after a unique draw are the people not yet assigned, which helps finish a full roster across several picks if the operator records each batch.

Verify the pick is random

Unique draws rely on Fisher-Yates: each position i swaps with a uniform index from 0 through i, chosen through crypto.getRandomValues with rejection sampling. That produces a uniform random permutation of the pasted list before the prefix is taken. Repeat mode calls a uniform index into the list once per requested pick. The Random Name Picker does not use Math.random.

A privacy note on the page states that names and results stay in the browser. No seed field is offered, so a draw cannot be replayed from a typed seed. If a dispute needs an audit trail, screenshot or copy the result immediately after the pick. Shared screens in a classroom should hide the full roster paste if student privacy is a concern.

Work a counting example with four names

Suppose the list is Alex, Blake, Casey, Drew and the draw asks for two unique names. Ordered pairs without replacement number P(4,2) = 4 × 3 = 12, and each pair is equally likely under a fair shuffle prefix. Chance Alex appears in the two picks is 2/4 = 1/2. Chance Alex is first is 1/4.

With repeats allowed and count 2, each position has four choices, so 16 ordered outcomes exist and (Alex, Alex) becomes possible. Expected number of times Alex appears across two independent picks is 2 × (1/4) = 1/2. Running the Random Name Picker under both unique settings with the same four-name list shows duplicates only when repeats are allowed.

Prepare a clean roster before drawing

Before a graded cold call or a prize draw, paste the roster into a plain text editor and remove blank lines, trailing commas, and accidental duplicate spellings. The Random Name Picker treats each non-empty token as a separate pool entry, so "Alex" on two lines counts as two tickets unless the list is cleaned.

Prefer one name per line for long class lists; comma separation works for short lists copied from a sheet row. After a unique multi-winner draw, copy both the picked list and the remaining names if later rounds must exclude prior winners. Replacing the paste with only the remaining names keeps the next unique draw inside the reduced pool without relying on memory.

For alternating speakers, keep count at 1 and unique Yes is optional when each press uses the full roster again. If the rule is that nobody is called twice until everyone has spoken once, either shrink the paste after each pick or raise count and draw a full unique ordering in one press, then read down the list in order.

FAQ

Closing summary

The Random Name Picker turns a pasted roster into one or more fair selections with an explicit unique-or-repeat control. Unique picks shuffle via Fisher-Yates and crypto.getRandomValues; repeat picks sample the list independently. Use it for cold calls and giveaways, keep rosters local to the browser, and record results when an audit copy is required.
