Collection FAQ
Extra context around when to use this toolkit and where to start.
Are the coin flips and dice rolls truly random?
Yes. Tools use standard browser pseudo-random algorithms or the Web Crypto API, providing unbiased distribution across large batches of trials.
Can I pick multiple unique winners from a name list?
Yes. Random Name Picker and List Randomizer allow you to draw multiple items with or without replacement so the same entry is not picked twice.
Can I roll custom dice with modifiers?
Yes. Roll a Dice supports various side counts (d4, d6, d8, d10, d12, d20, d100), custom side numbers, repeat rolls, and static arithmetic modifiers.
