How to Verify Wild Originals Are Provably Fair
A step-by-step walkthrough of provably fair verification for Wild Originals — learn how to find your bet data, understand seeds and nonces, run the HMAC-SHA512 hash, convert the result to a game outcome, and verify it matches your actual result independently.
How Do You Verify a Wild Originals Bet?
Key Takeaways- Wild Originals use HMAC-SHA512 with a server seed (key) + client seed:nonce (message) to generate every game result.- You can verify any bet after rotating your seed pair — the revealed server seed unlocks the full calculation.- Each game type (crash, dice, mines, limbo) maps the same HMAC output to a game result through a published, deterministic formula.- If a computed result doesn't match what you received, you have cryptographic proof of manipulation.
This lesson focuses specifically on how Wild.io Originals implement provably fair verification using HMAC-SHA512. For a broader introduction to what provably fair means and how it works across different casinos, see What Provably Fair Actually Means and How to Verify a Provably Fair Bet.
By the end of this walkthrough, you'll be able to independently confirm that any Wild Originals round you've played was generated fairly — without relying on Wild.io's own verification widget.
How Does the Wild Originals Seed System Work?
Every Wild Originals game uses the same three-input system: server seed, client seed, and nonce. If you're new to these concepts, the Provably Fair Casino Trust course explains the cryptographic foundations. Here's the Wild.io-specific implementation:
- Server seed — Generated by Wild.io before your session. You see its SHA-256 hash as a commitment; the actual seed stays hidden until you rotate to a new seed pair.
- Client seed — Wild.io generates a default, but you can change it to any string in the game's fairness settings.
- Nonce — Increments automatically with each bet under the same seed pair.
Wild.io detail: You can rotate your seed pair at any time from the provably fair panel in any Originals game. Once you rotate, all previous bets under that pair become fully verifiable because the server seed is revealed.
What Are the Step-by-Step Verification Steps?
Step 1: Find Your Bet in History
Open your bet history on Wild.io. Each completed bet shows:
- The game played (crash, mines, dice, etc.)
- Your bet amount and result
- A link to the provably fair details
Click into the bet details to access the seed information. You'll see:
- Server seed hash — the SHA-256 hash that was shown to you before the round
- Server seed (revealed) — the actual seed, shown only after the seed pair rotates
- Client seed — the seed you (or the system) provided
- Nonce — the bet number for this seed pair
Step 2: Copy the Seed Data
You'll need three values for verification:
1Server seed: a1b2c3d4e5f6... (revealed after rotation)2Client seed: your-custom-seed-here3Nonce: 42
Important: The server seed is only revealed after you rotate to a new seed pair. This is by design — if the server seed were visible during play, the commitment scheme would be broken. Once you rotate, all previous bets under that seed pair become fully verifiable.
Step 3: Verify the Hash Commitment
Before checking the game result, first confirm that the server seed matches the hash you were shown:
- Take the revealed server seed
- Compute its SHA-256 hash
- Compare this to the server seed hash that was displayed before the round
You can do this with any SHA-256 tool — online calculators, command-line utilities, or programming libraries.
1# Command-line verification (Linux/Mac):2echo -n "a1b2c3d4e5f6..." | sha256sum
If the computed hash matches the one shown before your bet, the server seed was committed honestly. If it doesn't match, something is wrong — the casino changed the seed after commitment, and you have cryptographic proof of fraud.
Step 4: Combine Seeds with HMAC-SHA512
Now compute the game result. Wild Originals uses HMAC-SHA512 (Hash-based Message Authentication Code with SHA-512) to combine the seeds:
HMAC-SHA512(key: server_seed, message: client_seed:nonce)
The message format concatenates your client seed, a colon separator, and the nonce. The server seed serves as the HMAC key.
1// JavaScript example using Node.js crypto:2const crypto = require('crypto');34const serverSeed = 'a1b2c3d4e5f6...';5const clientSeed = 'your-custom-seed-here';6const nonce = 42;78const hmac = crypto.createHmac('sha512', serverSeed);9hmac.update(`${clientSeed}:${nonce}`);10const hash = hmac.digest('hex');1112console.log(hash);13// Outputs: 64-character hex string
This produces a 128-character hexadecimal string (512 bits) that is the raw material for your game result.
Step 5: Convert Hash to Game Result
This step varies by game, because different games need different types of random outputs:
Dice: Take the first 8 hex characters of the hash, convert to a decimal integer, then map to a number between 0 and 99.99 using modulo arithmetic.
1const decimalValue = parseInt(hash.substring(0, 8), 16);2const diceResult = (decimalValue % 10000) / 100;3// e.g., 52.37
Crash: The hash is converted to a crash point multiplier. The first 8 hex characters map to a number, and a formula transforms it into the exponential distribution that produces crash multipliers (with a 1/33 chance of an instant 1.00× crash built in for the house edge).
Mines: The hash generates a sequence of mine positions. Starting from the hash output, positions are derived through iterative extraction — the first mine position from one segment, the second from the next, ensuring no duplicates.
Limbo: Similar to crash — the hash converts to a multiplier through the inverse of a uniform random variable, producing the characteristic distribution where low multipliers are common and high multipliers are rare.
Each game documents its specific conversion algorithm in its provably fair description. The point is: the same HMAC-SHA512 output feeds into a deterministic, published formula that anyone can replicate.
Step 6: Compare to Your Actual Result
Take the game result you computed in Step 5 and compare it to the result you actually received during the game.
- If they match: The round was generated fairly. The server committed to the seed before your bet, your client seed contributed to the outcome, and the math checks out.
- If they don't match: Something is wrong. Either you made a calculation error (re-check your inputs), or the casino generated a different result than their seeds should have produced.
What Does a Failed Verification Mean?
If your computed result genuinely doesn't match the game's reported result (and you've double-checked your inputs), you have cryptographic evidence of manipulation. This is serious — it means the casino either:
- Used a different server seed than the one committed
- Applied a different algorithm than documented
- Altered the result after generation
This is exactly the scenario provably fair systems are designed to expose. Screenshots and hash records become evidence. Share findings on community forums, and report to relevant authorities if applicable.
Key insight: In practice, reputable provably fair casinos pass verification because the system makes cheating detectable and catastrophically damaging to reputation. The value of provably fair isn't that you catch fraud — it's that the system makes fraud irrational to attempt.
What Tools Can You Use for Independent Verification?
You don't have to write code yourself. Several tools can verify provably fair results:
- Browser console: Open your browser's developer tools (F12), go to Console, and run the JavaScript examples above directly.
- Online HMAC generators: Web-based tools where you paste your seeds and get the HMAC output.
- Command-line tools: OpenSSL and standard Unix utilities can compute HMAC-SHA512 hashes:
1echo -n "your-client-seed:42" | openssl dgst -sha512 -hmac "server-seed-here"
- Open-source verification scripts: Community-built tools on GitHub that automate the full verification for specific game types. Search for "provably fair verification" to find them.
The best verification is one you run yourself, using tools you trust, on a machine you control. That's the whole point — you don't need to trust the casino's verification widget, because you can replicate the math independently.
How Does It All Come Together?
Provably fair verification transforms casino gambling from "trust us" to "verify it." For Wild Originals games, the process is:
- Before play: Note the server seed hash (your proof of commitment)
- During play: Your client seed and nonce contribute to every result
- After rotation: The server seed is revealed, unlocking verification
- Verification: Hash the server seed (confirm commitment), compute HMAC-SHA512 (derive result), convert to game outcome (compare to what you received)
You don't need to verify every single bet. But knowing you can — and occasionally doing so — is what keeps the system honest. The casino knows that any round could be audited by any player at any time.

And remember: play safe — provably fair means the math is honest, but the house edge still applies to every bet.
