Trust & fairness · Two different claims
Provably Fair vs. Random: What's the Difference?
"Random" and "provably fair" sound similar but promise very different things. One asks you to trust the result; the other lets you verify it. Here's why the gap matters.
The distinction that mattersA lot of tools say they're "random." Fewer are "provably fair." The difference isn't marketing — it's whether a buyer has to trust the outcome or can actually check it. For anything with money on the line, that gap is everything.
"Random" means unpredictable
A random result is one you couldn't predict in advance. Good randomizers use solid random number generation to get there, and for casual use that's plenty. But randomness alone leaves no record — once the draw is done, there's nothing to point to. You're asking people to take your word that it was fair.
"Provably fair" adds verification
Provably fair keeps the unpredictability and adds a second property: the result can be reproduced and checked afterward. It runs from a cryptographic seed captured in a shareable link, so anyone can replay the exact draw and confirm it. Random asks for trust; provably fair offers proof.
Side by side
| Property | Just "random" | Provably fair |
|---|---|---|
| Unpredictable before the draw | Yes | Yes |
| Leaves a shareable record | No | Yes |
| Buyer can reproduce it | No | Yes |
| Tampering is detectable | No | Yes |
| Requires trusting the operator | Yes | No |
Why breakers should care
In a card break, "it was random" doesn't settle a dispute — a replay link does. Choosing a provably fair tool means you never have to win an argument about a draw; the math wins it for you. That's the difference between a draw that can't be questioned and one that can.

Is provably fair more random than random?
No — both are genuinely random. Provably fair adds verifiability on top, so the result can be reproduced and checked afterward.
Do I need provably fair for a card break?
If money and trust are involved, yes. It removes disputes by letting buyers verify the draw themselves.
How does verification work?
The draw runs from a seed captured in a link; opening it reproduces the exact result. See how provably fair works.
