ToolWisp Random Number Generator creates random whole numbers between a minimum and maximum value you choose. Generate a single number for a quick draw or create a larger list for games, samples, classroom activities, giveaways, testing, and randomized selections.
Need unique results? Turn on No duplicates and every value in the generated list will be different.
A no-repeat random number generator is useful when each result should only be selected once. For example, if you need 10 unique numbers between 1 and 100, enable No duplicates and ToolWisp will produce 10 different values.
When No duplicates is enabled, the number of requested results cannot be larger than the number of possible integers in the selected range. For example, the range 1–10 contains only 10 unique whole numbers.
Use any minimum and maximum whole number, including negative values.
