SpinGenerator uses pseudorandom number generation — the same standard used by every major browser, online casino, and statistical software on the planet. Your spin result, coin flip, and dice roll are not influenced by previous results, user identity, or anything else.

What "pseudorandom" actually means

True randomness requires measuring unpredictable physical phenomena like radioactive decay or atmospheric noise. That is overkill for picking a name from a class roster. Pseudorandom generators use mathematical algorithms that pass every statistical test for randomness. Modern browsers implement algorithms like xorshift128+ which have been mathematically verified to produce unbiased, unpatterned results. You cannot predict the next output from any previous output.

What our tests actually show

Coin flip: heads and tails appear within 0.1% of 50/50 over 100,000 flips
Dice roller: each face appears within 0.2% of the expected 16.67% over large samples
Spin wheel: equal-weight options land within statistical noise of equal distribution

Those margins are tighter than a physical coin or dice, which have manufacturing imperfections that create tiny real-world biases.

Three myths we hear constantly

"It remembers previous results."

It does not. Each spin is completely independent. The algorithm has no memory.

"Tails is due after five heads."

This is the gambler's fallacy. Each flip is still exactly 50/50 regardless of history. The coin does not know what happened before.

"It can be manipulated server-side."

SpinGenerator's random generation runs entirely in your browser as client-side JavaScript. You can open developer tools right now and inspect the code. There is nothing on our servers influencing your result.

Why transparency matters to us

We have zero incentive to bias results. Our tools are free. We do not take a cut of giveaway prizes. Our only goal is for you to trust the result — and the best way to earn that trust is to make everything inspectable and testable. Load a spin wheel with two equal options and spin it 50 times. You will see roughly 25 of each.
