Random Tools

Get random numbers, or choose from / shuffle a list of items, using uniform distribution.

Having a uniform distribution means each candidate has an equal chance of being selected on any given roll.

Random Numbers

Presets

Instructions

Number chooser selects a number from min to max (inclusive). Step defines the increment between numbers. For instance, Use Min 1, Max 6, Step 1 to simulate a six-sided die. Use Min 2, Max 10, Step 2 to choose even numbers from 2 through 10.

Step increments are relative to the minimum number, so Min 0, Max 5, Step 3 will result in either 0 or 3. Using Step of 0 will result in an arbitrary floating point value.

Use the Presets buttons for convenient Dn dice roles.

Random Items

Presets

Instructions

Enter a list of items one item per line, then click Shuffle to arrange them in random order or Pick One to randomly select one item from the list.

If you want to select multiple items at a time, use shuffle and then look at e.g. the last 5 items in the list.

Use the Presets buttons to populate the list with coin toss, directions, icecream flavors, or days of the week options. Doing so replaces any items in the list.
