The Provably Fair Cheat Sheet: Which Casino Games Can You Verify (And Which You Can't)
I keep a laminated card in my desk drawer. It's from my consulting days — a one-page reference sheet I made for a client's compliance team that listed every game provider in their lobby and whether players could independently verify results. That card saved us hours of confused conversations every week.
This article is the public version of that card. Bookmark it. Come back to it every time you're looking at a new casino and wondering: "Can I actually check if this game is fair, or am I just trusting someone's word for it?"
The Short Version
If a game was built by a third-party provider (Pragmatic Play, Playtech, NetEnt, Evolution, etc.), you cannot verify individual results. These games use internal random number generators that are audited by testing labs but never exposed to players.
If a game was built in-house by a crypto casino (Stake Originals, BC.Game house games, etc.), it is likely Provably Fair and you can verify every single result yourself using cryptographic proofs.
That's the rule. Now let me give you the full breakdown.
Providers You CANNOT Verify (Traditional RNG)
These companies build games that run on their own servers. The casino renting the game has no access to the underlying random number generator, and neither do you. Fairness is guaranteed through periodic third-party audits — not real-time cryptographic proof.
Slot Providers
Pragmatic Play — Gates of Olympus, Sweet Bonanza, The Dog House, Sugar Rush. Probably the most popular slot provider in crypto casinos right now. Certified by BMM Testlabs and Gaming Labs International. You'll find their games in almost every crypto casino lobby, sitting right next to Provably Fair originals. Not verifiable by players.
Playtech — Age of the Gods series, Buffalo Blitz, Jackpot Giant. One of the oldest providers in the industry, publicly traded company. Audited by eCOGRA. Their RNG has been running since the early 2000s. Solid track record, but completely opaque to players. I wrote a detailed piece on why Playtech can't offer Provably Fair if you want the technical explanation.
NetEnt (Evolution Group) — Starburst, Gonzo's Quest, Dead or Alive. Swedish-built, now owned by Evolution. Audited by eCOGRA and various national regulators. Clean reputation, but same story: you trust the audit, not the math.
Microgaming (Games Global) — Mega Moolah, Immortal Romance, Thunderstruck. The provider behind the biggest progressive jackpot in online gambling history. Now operating under Games Global. eCOGRA audited. Not verifiable.
Play'n GO — Book of Dead, Reactoonz, Rich Wilde series. Swedish provider, popular in European markets. GLI certified. Same closed-RNG model as everyone else on this list.
Hacksaw Gaming — Wanted Dead or a Wild, Chaos Crew, Le Bandit. Newer provider that's gotten huge in crypto casinos. Their games look modern and play fast, but the verification model is traditional. Audited, not transparent.
Push Gaming — Jammin' Jars, Fat Rabbit, Razor Shark. UK-based, UKGC licensed. Solid games, but you're trusting the regulator, not checking the math yourself.
Nolimit City — Mental, San Quentin, Tombstone. Known for high-volatility slots that attract crypto gamblers. Despite being popular on Provably Fair casinos, their games themselves are not Provably Fair. Important distinction.
Relax Gaming — Money Train series, Temple Tumble, Dream Drop Jackpot. Another provider commonly found on crypto platforms. Audited by GLI. Not verifiable.
Big Time Gaming (BTG) — Bonanza, Extra Chilli, Megaways series. Invented the Megaways mechanic. Licensed and audited. Not Provably Fair.
Red Tiger — Now owned by Evolution. Gonzo's Quest Megaways, Piggy Riches. Same audit-based model as the parent company.
Thunderkick, ELK Studios, Yggdrasil, Blueprint Gaming, iSoftBet, Wazdan, Endorphina, BGaming — All traditional RNG. All audited by various testing labs. None offer player-side verification.
Live Casino Providers
Evolution Gaming — Lightning Roulette, Crazy Time, Monopoly Live, all live blackjack and baccarat tables. The absolute dominant force in live dealer gaming. Their games use physical equipment (real wheels, real cards, real dealers) filmed in studios. There's no cryptographic seed to verify because the randomness comes from physical events. You're watching a real roulette ball land on a real wheel — but you're trusting that the equipment isn't rigged. Evolution is heavily regulated and audited, but player-side verification is structurally impossible for live games.
Pragmatic Play Live, Playtech Live, Ezugi, Vivo Gaming, SA Gaming — Same concept. Real dealers, real equipment, no cryptographic verification possible. Regulated and audited, but not transparent in the Provably Fair sense.
What "Audited" Actually Means
When I say these providers are "audited," I mean that independent testing labs like eCOGRA, GLI, BMM Testlabs, or iTech Labs periodically examine their random number generators. They run millions of simulated spins and verify that the statistical distribution matches the claimed return-to-player percentages.
These audits are legitimate. I've been present for some of them during my consulting work. But they happen periodically — maybe once or twice a year — and the results are published as certificates, not real-time data. Between audits, you're trusting that nothing has changed.
Is that enough? For most regulated markets, yes. For players who want mathematical certainty on every single bet? No.
Games You CAN Verify (Provably Fair)
These are games built by crypto casinos themselves, using cryptographic commitment schemes that let you verify every result after every round. Here's who does it and what games they offer.
Stake Originals
The gold standard for Provably Fair implementation. Every original game on Stake publishes server seeds, client seeds, and nonces. Their verification documentation is public and straightforward.
- Crash — The classic. Multiplier rises until it crashes. You can verify the exact crash point.
- Dice — Roll over/under a target number. Fully verifiable outcome.
- Mines — Grid of tiles hiding mines. Mine positions determined by seeds, verifiable after reveal.
- Plinko — Ball drops through pegs. Path determined by seeds.
- Hilo — Guess higher or lower. Card sequence from seeds.
- Keno — Number draw. Drawn numbers from seeds.
- Limbo — Hit a target multiplier. Result from seeds.
- Diamond Poker, Video Poker, Blackjack (original), Baccarat (original) — All Provably Fair.
BC.Game Originals
Strong Provably Fair implementation with detailed technical documentation. BC.Game publishes their algorithms openly.
- Classic Crash — Same concept as Stake's Crash. Verifiable.
- Classic Dice — Verifiable dice roll.
- Hash Dice — Dice game based directly on hash output. Transparent.
- Plinko, Mines, Keno, Limbo, Wheel, Ring — All verifiable.
- Cave of Plunder, Sword, Tower Legend — BC.Game exclusives, all Provably Fair.
Roobet Originals
- Crash — Provably Fair, same HMAC-SHA256 model.
- Dice — Verifiable.
- Mines, Towers — Verifiable.
Duelbits Originals
- Crash, Dice, Mines, Plinko, Hilo — All Provably Fair.
Other Provably Fair Casinos
Primedice (dice only, one of the original Provably Fair sites), BetFury (originals), Wolf.bet (originals), Winz.io (selected originals). The Provably Fair ecosystem is growing — more crypto casinos are building original games with built-in verification because players are starting to demand it.
How to Verify These Games
Every Provably Fair game follows the same basic pattern: the casino commits to a server seed hash before your bet, you provide a client seed, the round plays out, and afterwards you can check the math. I built a free Provably Fair Verifier tool that handles the calculation for you — paste in your seeds, select the game type, and verify in seconds. For the full technical explanation, read my breakdown of how Provably Fair works.
The Gray Zone: "Provably Fair" Claims Without Proof
This is where it gets tricky, and where my experience as an industry insider becomes useful.
Some smaller crypto casinos claim to be "Provably Fair" but don't actually provide the tools or data needed for verification. Watch out for these red flags:
- No server seed hash shown before the bet. If you can't see the commitment before you bet, there's no proof the casino didn't change the outcome after seeing your wager.
- Server seed never revealed after the round. Some casinos show the hash but never give you the actual seed to check against it. Useless.
- No client seed option. If you can't set or change your own client seed, the casino controls all inputs to the result. That's not Provably Fair — that's just regular RNG with extra steps.
- Verification tool is "coming soon" forever. If they've been promising a verification page for six months, they're not Provably Fair. They're using the term as marketing.
- Third-party games labeled as Provably Fair. If a casino says their Pragmatic Play slots are "Provably Fair," they're either confused or lying. Third-party games cannot be Provably Fair.

The Bottom Line
Next time you're sitting in front of a crypto casino lobby with 3,000 games, remember this: probably 95% of those games are traditional RNG from third-party providers. They're audited, they're generally trustworthy, but you cannot verify them yourself. The remaining 5% — the casino's original games — are likely the only ones where you can actually check the math.
That doesn't mean you should only play Provably Fair games. Plenty of people enjoy Pragmatic Play slots and Evolution live tables without ever worrying about verification. But if transparency matters to you — if you want to know, not just believe — then you need to know which games give you that option.
Use our Provably Fair Verifier to check your game results. Read up on KYC triggers so you know what to expect when you win. And if a casino claims "Provably Fair" but won't give you the seeds — find a different casino. There are enough honest ones out there.
