Ladder Game & Random Picker (Roulette, Teams, Seating, Lotto)
Enter names to pick winners, split teams, play the ladder game, spin a roulette, flip cards or arrange seats. Dice, coin and lotto numbers too. Names never leave your browser and randomness comes from Web Crypto.
The link carries only the candidate list (never the result, so every opening draws fresh). The list sits after the # in the address and is not sent to a server.
Pick people from the list. Picking several at once never returns the same person twice.
Candidates become the lanes; click a name to climb down the ladder. Each lane ends at a result you write below (prize, nothing, errand…).
Candidates go on a wheel. Add *3 after a name for a slice three times as wide (up to *10, e.g. Pizza*3). The result is decided before the spin; the wheel just stops on it.
Face-down cards you flip one by one — handy for passing a phone around a group. Which card wins is decided when the cards are shuffled.
Seats the names from the list at random. Seats are numbered from 1, left to right starting at the top-left.

Draws six different numbers from 1–45 plus one bonus number, shown in ascending order.
For fun only. Every number is equally likely and nothing guarantees a win.
Make several different bingo cards from a word list and print them, together with a call sheet for the host. Enter the same seed to recreate the same set of cards.
The same word list and seed give the same cards — handy for reprinting a lost card or matching the call sheet.
Words never repeat on a card and no two cards are laid out identically. When printing, keep scale at 100% and margins normal or smaller.
Make printable addition, subtraction, multiplication and division worksheets. The same seed gives the same worksheet, so you can print the answer key later.
Leave empty to create a new one. Write this number down to recreate the same worksheet.
How it stays fair
- Randomness comes from the browser's cryptographic generator (Web Crypto) with rejection sampling so no value is favoured. Math.random is never used.
- The roulette, cards and ladder animations only show a result that is already decided. Spin speed or click timing cannot change it.
- Share links carry only the candidate list. Putting the result in a link would repeat the same result and be unfair.
- Names are neither sent to a server nor stored. They disappear when you close the page.
FAQ
Is the ladder game really fair?
Rungs are placed randomly with no two adjacent on the same row, and every pair of neighbouring lanes gets at least one. A ladder always maps every start to a different end, so nobody shares a result.
Does the same link give the same result?
No. The link holds only the list and every opening draws again.
The motion bothers me.
Untick "Drumroll effects" to get results immediately. It switches off automatically if your device asks to reduce motion.
