Numbers 1 to 8 Wheel
Spin to land on a random number from 1 to 8, each with an equal one in eight chance. Built for eights: lanes, brackets, tables and eight-player games.
Fair by design: each spin draws from your browser’s cryptographic random number generator, giving every entry an equal 1-in-8 chance. No server is involved.
8 entries on the wheel, up to 500.
Every entry has an equal 1-in-8 chance. Write "1 *3" to make an entry three times as likely.
The entries travel in the part of the link after the #, which browsers never send to a server. Nobody, including us, can read a shared wheel from a log.
Please keep the attribution link on the last line. It is the only thing we ask in return, and it is what pays for the wheel being free.

When to spin the Numbers 1 to 8 Wheel
Eight is the number of brackets and lanes. Swimming heats and sprint finals run eight lanes, knockout tournaments seed eight players a side, and plenty of board games top out at eight around the table. This wheel assigns any of those slots fairly: spin for a lane draw, for which quarter-final pairing kicks off the evening, or for which of eight tables presents first. Each slice holds an equal one in eight chance, 12.5 percent, on every spin, and every spin is independent, so a number that just came up is exactly as likely next time. It also stands in for a d8 when the dice bag is elsewhere, though tabletop players get more from the dedicated d8 roller, which can roll several dice and add them up. As always, edit the entries to rename slots or trim the count, and the odds rebalance instantly.
8 slices: odds, streaks and repeats
Each of the 8 slices wins a spin 1 in 8, or 12.5%. That sounds rare, yet repeats arrive early: by spin 4 the chance that some number has already come up twice passes 50%, the same maths as the birthday problem. Landing on every one of them, from 1 to 8, takes about 22 spins on average, which is why a no-repeat round is the quicker way to work through the whole list.
Tips for spinning it in front of a group
- With 8 slices of 45° each, the numbers print large enough to read from the back of a room. Press Present for a full-screen wheel: Space or Enter spins and Esc returns to the page.
- Tick Remove after pick and each winner leaves the wheel: 8 spins work through all 8 numbers with none drawn twice, and Reset round puts 1 and the rest back.
- For a handicap in a family game, write "5 *2": 5 then lands 22.2% of the time against 11.1% for each other slice.
Frequently asked questions
What can I use a random number from 1 to 8 for?
Classic eights: drawing swimming or sprint lanes, seeding an eight-player bracket, picking one of eight tables or teams, or standing in for a d8 in a tabletop game.
Does the 1-8 wheel have the same odds as a d8?
Yes, both give every number a one in eight chance, 12.5%. For rolling several dice at once with totals, the dedicated d8 roller is the better fit.
Can I rename the numbers to lane or player names?
Yes. Replace the digits in the entry box with names or labels and the wheel picks among them with the same equal odds per slice.
