How to Use the Number Picker Wheel
This page covers the four selection modes, how the dice and raffle
presets work, how the random draw is actually calculated, the
number ranges people spin most often, and how this number wheel
spinner compares to a plain random number generator.
Table of Contents
Quick Start
1. Pick a mode
Tap Range, Odd Only, Even Only, or Custom in the setup panel.
2. Set the numbers
Enter a From/To range, or switch to Custom and add your own
values one at a time or by pasting a list.
3. Spin
Press Spin the Wheel, or tap the gold circle in the middle of
the wheel.
4. Read the result
The number lands above the wheel and in a popup, and it's
logged to your spin history and running stats.
Wheel Modes Explained
Range
Generates a whole number between the minimum and maximum you set,
anywhere from -1,000,000 to 1,000,000. If the span is wider than
20 numbers, only 20 slices are drawn on the wheel for
readability, but the actual draw still covers every value in your
range β not just the ones shown.
Odd Only / Even Only
Same range control, but limited to odd or even integers β
essentially an odd or even wheel layered on top of any range you
choose. Handy for parity drills in a math class or for splitting
a group into two teams by odd/even birth years, ticket numbers,
or IDs.
Custom
Type in exactly the numbers you want, including negatives,
decimals, and repeats. Adding a value twice puts it on the wheel
twice, which weights it toward a higher chance of being picked β
useful for giving certain prize tiers or outcomes better odds.
Common Number Ranges People Spin
Most people don't need the full -1,000,000 to 1,000,000 span β
they're solving one specific problem. Here are some of the most
common setups, and how to build them in a few seconds.
1 and 2
Type 1 in From and 2 in To for a coin-flip-style number
wheel β useful for deciding between two people, teams, or
choices when you want a number instead of heads or tails.
1 through 5
Good for rating scales, five-team draws, or picking one of
five stations in a rotation.
1 through 7
Matches a seven-day week, a seven-question quiz order, or a
group of seven players choosing turn order.
1 through 9
Useful for single-digit math drills or picking one of nine
remaining items in a game.
1 to 37
Set From to 0 for a 37-slot draw matching a European
roulette wheel, or use 1β37 for a raffle with 37 entries.
1 to 50
A common raffle ticket range β pair it with the Raffle:
1β50 preset and Remove After Pick so no number raffle wheel
ticket repeats.
To set up any of these, tap a Range in the setup panel, type
your From and To values, and press Apply. The wheel updates
instantly and the setup is saved in your browser for next time.
Where People Use This Wheel
Classrooms
Call on students by roster number, run odd/even math
practice, or assign presentation order without repeats.
Raffles and giveaways
Match the range to your ticket numbers and use Remove After
Pick so a winning number can't come up twice.
Tabletop games
Swap in a d4, d8, d12, or d20 preset for quick rolls when you
don't have physical dice on hand.
Team and task assignment
Number your team members and spin to decide turn order, who
presents first, or who picks a task next.
Digital Dice and Raffle Ranges
1β4
d4 dice roller
1β6
standard dice roller
1β8
d8 dice roller
1β10
random number 1β10
1β20
D20 dice roller
1β100
random number 1β100
For a raffle: set the range to match your ticket numbers (say,
1β150), turn on Remove After Pick, and spin once per prize. Each
winner drops out of the pool, so nobody wins twice in the same
round. When the pool empties, it reloads automatically for the
next event.
Number Wheel Spinner vs. a Plain Random Number Generator
A text-based random number generator prints a number the instant
you press a button. A number picker wheel does the same
underlying job β picking one random number from a set β but adds
a visible spin so a group can watch the draw happen together
instead of trusting a number that appeared silently on one
person's screen.
That matters for raffles, classroom calls, and streams: a wheel
spinner gives everyone in the room, or the chat, a shared moment
to watch the result land. Under the hood, this random number
picker uses the same logic described in the section below β the
wheel is simply the presentation layer.
How the Random Result Is Selected
The winning number is chosen the moment you press spin, before
the wheel starts turning β the animation is a reveal, not a live
simulation.
Selection uses the browser's Web Crypto API when it's available
and falls back to Math.random() when it isn't. Every entry on the
active wheel has an equal chance per slice, and duplicate custom
entries stay as separate slices, which is what creates weighted
odds in Custom mode.
Saving and Sharing a Wheel Setup
Your mode, range, and custom numbers are stored in your browser
automatically, so they're still there the next time you open this
page on the same device.
Select Share Wheel to copy a link that encodes your current
setup. Send it to a co-teacher, event partner, or player group,
and opening the link loads the identical range or custom list β
no manual re-entry needed.
