Is BC.Game Provably Fair? Full Transparency Breakdown

Yes — BC.Game offers provably fair gaming on its in-house original games. The platform uses a SHA-256 hash chain system that allows players to independently verify each game round. As with most crypto casinos, third-party slots and live dealer games from external providers operate under traditional RNG certification rather than provably fair verification.

Which BC.Game Games Are Provably Fair?

BC.Game has one of the largest collections of provably fair originals in the crypto casino space.

Provably Fair — BC Originals

• Crash
• Classic Dice
• Hash Dice
• Plinko
• Limbo
• Wheel
• Mines
• Tower Legend
• Keno
• Ring of Fortune
• Cave of Plunder
• Sword
• Beauties
• Video Poker
• Coinflip

BC.Game regularly adds new originals, and all of them include provably fair verification.

Not Provably Fair — Third-Party Games

• Slots from providers like Pragmatic Play, PG Soft, Hacksaw Gaming
• Live dealer tables from Evolution, Ezugi
• Sports betting outcomes

These use standard RNG audits and licensing rather than cryptographic verification.

What Algorithm Does BC.Game Use?

BC.Game uses a SHA-256 hash chain system — a slightly different approach from the HMAC-based systems used by some competitors:

1. Hash chain — BC.Game pre-generates a chain of 10 million SHA-256 hashes. Each hash is the SHA-256 of the next, creating a verifiable chain. The final hash is published publicly before any games begin.
2. Game hash — For each round, the next hash in the chain is used (working backwards from the published end point).
3. Game seed — A combination of the game hash and server-generated randomness determines the outcome.
4. Verification — Because each hash in the chain can be verified as the SHA-256 of the subsequent hash, players can confirm the entire sequence was pre-determined.

This hash chain approach means the entire sequence of outcomes is locked in before any player places a bet. BC.Game literally cannot change future results based on player behaviour.

How to Verify a Bet on BC.Game — Step by Step

1. Play any BC Original game and complete a round.
2. Click the “Fairness” or “Verify” button within the game interface.
3. Find the game hash for your specific round — this is displayed in your bet history.
4. Copy the hash and use a SHA-256 calculator to confirm it’s the pre-image of the next hash in the chain.
5. Use a third-party verifier like ProofBets’ Provably Fair Verifier to independently confirm the result.
6. Check against the public seed — BC.Game publishes the chain endpoint so anyone can verify the full sequence.

You can also check BC.Game’s white paper, which documents the hash chain system with worked examples.

Pro tip: BC.Game’s hash chain approach means you can verify not just your own bets but any round in the entire game history. The chain is publicly auditable.

Transparency Score: 8.5/10

Factor	Assessment
Provably fair originals	✅ All originals verified
Algorithm documented	✅ SHA-256 hash chain, detailed in white paper
Public hash chain	✅ Chain endpoint published
Third-party verification	✅ Works with independent tools
Client seed input	⚠️ Limited compared to HMAC systems
Nonce visibility	✅ Round-based chain position
Third-party game transparency	⚠️ Licensed/audited but not provably fair

BC.Game scores very well but loses half a point because its hash chain system gives players less direct influence over outcomes compared to client-seed-based HMAC systems. The overall fairness guarantee is mathematically equivalent, but some players prefer having direct seed input.

What Makes BC.Game’s System Unique

• Hash chain pre-commitment — The entire outcome sequence is locked before any bets are placed, making manipulation mathematically impossible.
• Public auditability — Anyone can verify the full chain, not just their own bets.
• White paper documentation — BC.Game provides detailed technical documentation of its fairness system.
• Large original library — More provably fair games means more of your playing time is verifiable.

Limitations to Be Aware Of

• Less player input — Unlike HMAC-based systems where you set a client seed, BC.Game’s hash chain approach gives players less direct influence on outcome generation.
• Third-party games excluded — The majority of BC.Game’s 8,000+ game library comes from external providers and isn’t provably fair.
• Complexity — Hash chains are harder to understand intuitively than the seed+nonce approach, which may deter casual verification.

FAQ

How does BC.Game’s hash chain differ from other provably fair systems?

Most casinos use HMAC-SHA256 with server seed + client seed + nonce. BC.Game uses a pre-generated SHA-256 hash chain where the entire sequence is committed upfront. Both are cryptographically sound — the hash chain approach trades player seed input for full-chain auditability.

Can BC.Game manipulate Crash results?

No. The hash chain is pre-generated and publicly committed. Each crash point is derived from a hash that was locked in before any player wagered. You can verify this using the chain’s public endpoint hash.

Are BC.Game slots provably fair?

No. Slots from third-party providers use traditional RNG certification. Only BC Original games support provably fair verification.

Can I verify old bets on BC.Game?

Yes. Because the hash chain is sequential and publicly committed, you can verify any historical round — even rounds you didn’t participate in. Use our Provably Fair Verifier to check.

Is BC.Game’s provably fair system trustworthy?

Yes. The SHA-256 hash chain is a well-established cryptographic approach. It’s the same algorithm that secures Bitcoin transactions. The pre-commitment model means outcomes are determined before bets are placed, eliminating the possibility of real-time manipulation.
