Random Number Generator: Pick a Number From Any Range

It takes four steps. The controls are under Numbers.

1. 1Pick Range. It is the first of three buttons at the top of Numbers. It is already on when the page opens.
2. 2Type a Minimum and a Maximum. Both numbers are included. The wheel opens set to 1 to 10.
3. 3Leave How many at 1 for one number. Raise it to draw more.
4. 4Press Spin. One number opens a box called Your number. Many numbers show in the order they were drawn.

Three buttons at the top of Numbers set what goes on the wheel. They are Range, Custom and Digits.

• 

  Range

  Range puts every whole number from your Minimum to your Maximum on the wheel. Interval sets the gap between numbers. Exclude removes numbers you list. Separate them with commas or spaces.

• 

  Custom

  Custom lets you type your own numbers in the Your numbers box. Separate them with commas, spaces or new lines. You need at least 2.

• 

  Digits

  Digits builds a number one digit at a time. Choose 1 to 6 digits. Each digit gets its own spin. The Lowest digit and Highest digit start at 0 and 9. Four digits might give 0357. Leading zeros stay, and a digit can repeat.

• Even numbers up to 100: Minimum 2, Maximum 100, Interval 2. You get 50 numbers.
• Odd numbers up to 99: Minimum 1, Maximum 99, Interval 2. You get 50 numbers.
• Multiples of 5 up to 100: Minimum 5, Maximum 100, Interval 5. You get 20 numbers.
• 1 to 20 without 7 and 13: Minimum 1, Maximum 20, then type 7, 13 into Exclude. You get 18 numbers.
• Negative numbers: type a minus sign before the number. Negative 10 to 10 gives 21 numbers, and zero is one of them.

Your Maximum joins the wheel only if the Interval lands on it. Minimum 1, Maximum 10 and Interval 4 gives 1, 5 and 9.

Decimals and negative numbers work in Custom. Use a dot for decimals, like 2.5. Do not type 1,000, because the comma splits it into 1 and 0. A number you type twice gets two slices. That doubles its chance.

1. 1Set How many to the number of draws.
2. 2Turn on No repeats.
3. 3The wheel spins once for each number. After each spin, the winner leaves the wheel until the set ends. So every number in the set is different. This is also called drawing without replacement.

• When the set ends. The next spin starts from the full wheel again.
• Remove each winner. It works across spins instead. It keeps winners off the wheel until you press Reset. People also call this elimination. Use it when you spin one number at a time and nobody should win twice.
• Enough numbers. No repeats needs enough numbers. Ask for 5 numbers from a wheel of 4 and you get an error. It says Only 4 different numbers are on the wheel.
• Custom duplicates. A number you type twice has two slices. No repeats removes one slice per draw. So that number can still come up twice.
• Timing. Sets take a little time. Each spin lasts about 2 seconds, so 100 numbers take a few minutes. Press Stop to end early. The numbers drawn so far are kept.

• Draw raffle tickets. Say your tickets run from 1 to 250 and you need 3 winners. Set Minimum 1, Maximum 250 and How many 3. Turn on No repeats. One set gives three different tickets.
• Call on a student. Give each student a number. Turn on Remove each winner. Spin once for each question. Nobody is picked twice until you press Reset. To pick by name, use the Spin the Wheel page.
• Practice counting. Spin 1 to 10 for early counting. For skip counting, raise the Interval. Minimum 0, Maximum 100 and Interval 10 puts the tens from 0 to 100 on the wheel.
• Set a turn order. Number your 4 players from 1 to 4. Set How many to 4 and turn on No repeats. The numbers show in the order they were drawn. The first number drawn goes first.
• Fill football squares. A squares grid needs each digit from 0 to 9 once on each side. Set Minimum 0, Maximum 9 and How many 10. Turn on No repeats. Draw once for the top and once for the side.
• Choose a sample. To check 10 files out of 500, set Minimum 1, Maximum 500 and How many 10. Turn on No repeats. Then match the numbers to your files.

• You can draw 1 to 100 numbers in one set.
• A Range wheel holds up to 10,000 numbers on a desktop. On a screen under 640 pixels wide, it holds up to 1,000. For more, shrink the range or raise the Interval.
• Range needs whole numbers. Use Custom for decimals.
• A crowded wheel may have slices too thin to show each number. The winner still shows in the result.
• Your numbers stay in your browser, and ShuffleWheel does not receive them. The last 10 results and the Times drawn counts clear when you reload.

These settings do not change the odds. On a phone, they sit under Settings.

• To roll dice with sides, use the Dice Roller, which rolls a d4, d6, d8, d10, d12, d20 or a custom die.
• To pick a person instead of a number, use the Random Name Picker.
• To pick a letter from A to Z, use the Random Letter Generator.
