How Provably Fair Works

You shouldn’t have to take our word for it. Every result on L0TT0 comes from a provably fair system — meaning you can check the math yourself after the fact.

Each spin, roll, or card uses a server seed, your client seed, and a nonce. Together they produce an outcome that can’t be changed once the bet is placed.

Same inputs, same result — every time. That’s the whole point.

New to the concept? What is Provably Fair?

What That Means for You

Lots of sites say “provably fair” and leave it at that. We actually give you the seeds, the tools, and the steps to verify any bet.

Before a seed is revealed, you see its hash — a commitment we can’t rewrite. After you rotate your client seed, the old server seed opens up and every bet tied to it becomes checkable.

No hand-waving. Just data you can run through yourself.

The Three Pieces

Results are generated with standard crypto — same family of stuff used in wallets and security tooling. Three inputs, one deterministic output.

Feed in the same server seed, client seed, and nonce and you’ll always get the same result. Nobody can tweak it after the fact without breaking the hash.

Server Seed

A random value we generate on our side. Before you play, we show you a hash of it — that’s the commitment. We can’t swap the seed later without the hash failing to match.

When you rotate your client seed, the old server seed is revealed. That unlocks verification for every bet that used it.

Client Seed

Yours from day one. Change it whenever you want — you’re not leaving the randomness entirely up to us.

Nonce

A counter that ticks up with each bet — 0, 1, 2, and so on. Same seeds, different nonce, different outcome.

Rotating your client seed resets it back to zero.

What’s a nonce?

Seed Combination (HMAC-SHA512)

We combine all three with HMAC-SHA512 and map the output to the game’s rules — cards drawn, dice rolled, slots hit, whatever the game needs.

  • Same inputs → same output (reproducible)
  • Can’t predict the output without knowing the server seed
  • Can’t change the output once the bet is locked in

Verify Any Bet

Theory is fine. The Verify Bet page is where you actually run the numbers.

Plug in:

  • Revealed server seed
  • Your client seed
  • Nonce
  • Game

Hit verify. If the output matches your bet, you’re done.

Replay Any Bet

Every bet on the site can be opened and replayed — same seeds, same nonce, same outcome on screen.

Handy when you want to see what happened, not just confirm a hash matched.

Provably fair isn’t a marketing line here — it’s how every game runs. Check a bet yourself, or open one from your history and replay it.
