A technical deep dive into blockchain verification, hash transparency, and
how WNNR.com proves every game outcome is truly random and unmanipulated.
In the world of crypto gaming, “provably fair” has become more than just a buzzword—it’s the gold
standard for transparency and trust. WNNR
Sportsbook has implemented one of the most sophisticated provably fair systems in the industry,
allowing players to independently verify every single game outcome. This comprehensive analysis will
break down exactly how this technology works, examine key games like Plinko, Dice, and Crash, and show
you how to manually verify fairness yourself.
What is “Provably Fair” Technology?
Provably fair is a cryptographic protocol that enables players to verify that each game outcome is
random and hasn’t been manipulated by the house. Unlike traditional online casinos where you simply
trust that the Random Number Generator (RNG) is fair, provably fair systems provide mathematical
proof that can be independently verified.
The Core Principle: Client Seed + Server Seed + Nonce
At WNNR Sportsbook, every provably
fair game follows this fundamental formula:
Game Result = SHA256(Client Seed + Server Seed + Nonce)
The server seed is generated by WNNR and its hash is shown before you play. The client seed is
either provided by you or generated on your behalf. The nonce is simply a counter that
increments with each game. After the game concludes, the original server seed is revealed,
allowing you to verify that the hash matches and that the outcome was calculated correctly.
Key Advantage: WNNR commits to the server seed hash BEFORE you play, meaning
they cannot change it afterward to affect the outcome. This eliminates any possibility of
post-game manipulation.

Plinko: The Physics-Based Classic
WNNR’s Plinko game takes the classic television game and adds cryptographic transparency. Each
ball drop’s starting position, peg collisions, and final slot are determined by the provably
fair algorithm. The game uses your seed combination to generate thousands of micro-decisions
that create the authentic Plinko physics simulation.
Verification Tip: After playing, you can check the detailed breakdown showing
how each bounce was calculated from your seed values.
Dice: Pure Probability Testing
The Dice game at WNNR Sportsbook
offers the simplest demonstration of provable fairness. You choose a number between 1-100 and
whether you want to roll over or under. The result is generated from your seeds and can be
verified in seconds. The simplicity makes it perfect for first-time provable fair verification.
Verification Tip: Use WNNR’s built-in verifier tool—just paste your seeds and
nonce to confirm the roll matched the promised outcome.
Crash: Real-Time Multiplayer Verification
Crash presents unique challenges for provable fairness since multiple players participate
simultaneously. WNNR solves this by generating a deterministic crash point from the initial seed
that applies to all players in that round. Everyone sees the same multiplier curve, and everyone
can verify the crash point independently after the game ends.
Verification Tip: Check that the crash point matches the hash shown before the
game started—all players in the same round will verify the same result.
Manual Verification: How to Check Hash Fairness Yourself
While WNNR Sportsbook provides
automatic verification tools, true crypto enthusiasts often prefer to manually verify game outcomes.
Here’s a step-by-step guide to independent verification:
Step 1: Record Your Game Details
Before playing any provably fair game at WNNR, note the server seed hash displayed. Also
record your client seed and the nonce value. WNNR conveniently provides a copy-paste format
for all these values.
Step 2: Play and Capture the Result
After the game concludes, the platform reveals the actual server seed. Record this along with
your final game result. WNNR also shows the “winning number” or outcome in raw form before
it’s translated to the game display.
Step 3: Verify the Server Seed Hash
Take the revealed server seed and hash it using SHA256. You can use any online SHA256
generator or command-line tool. The resulting hash MUST match the server seed hash shown
before the game.
Server Seed: d74ff0ee8da3b9806b18c877dbf29bbde50b5bd8e4dad7a3a725000feb82e8f1
SHA256 Hash: 2a9a2d6f4f6c2e7b7d8c9a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8b9c0d1 (must match
pre-game hash)
Step 4: Calculate the Game Result
Combine your client seed + server seed + nonce as a single string, then calculate SHA256 of
that combination. The first several characters of this hash (converted to hexadecimal)
determine your game outcome.
combined_string = client_seed + “:” + server_seed + “:” + str(nonce)
final_hash = sha256(combined_string)
// First 8 chars determine Dice result (00-99)
// Full hash determines Crash multiplier
// Multiple hashes determine Plinko path
Step 5: Match Against Game Outcome
Convert the relevant portions of your calculated hash to the game-specific format. For Dice:
first 8 chars as hexadecimal modulo 100 gives 0-99. For Crash: specific algorithm determines
multiplier. Compare with WNNR’s displayed result—they should match exactly.
Pro Tip: WNNR provides open-source verification code on their GitHub repository
that you can run locally for absolute certainty. This is the gold standard for technical users
wanting complete transparency.
WNNR’s Implementation: Beyond Basic Provable Fairness
WNNR Sportsbook goes beyond standard
provably fair implementations with several advanced features:
Multi-Game Seed Chains
WNNR allows seed chaining, where the outcome of one game becomes the client seed for the next.
This creates an unbreakable chain of verifiable results where each game depends on the previous
one, making manipulation mathematically impossible across gaming sessions.
Transparent Audit Logs
Every provably fair game at WNNR generates a complete audit log with timestamps, all seed values,
hash calculations, and the final result. These logs are accessible for 90 days, allowing for
retrospective verification or third-party auditing.
Experience True Cryptographic Transparency
Ready to test WNNR’s provably fair system for yourself? Experience games where you don’t have to
trust—you can verify. Every outcome, every multiplier, every Plinko bounce is mathematically
provable.
