What “provably fair” means
Provably fair is a cryptographic scheme that lets players verify every game result independently. The outcome of a round is fixed and published as a hash before any bet is placed, so the operator cannot change it mid-round — and after the round the revealed seed proves it. Every Turbo Games title uses this scheme.
How the commit-and-reveal scheme works
- Commit. Before a round opens, the game server generates the round's seed and publishes its cryptographic hash. The hash pins the outcome without revealing it.
- Play. You place your bet and play the round — cash out of the crash curve, flip tiles in mines, release the Vortex ring. Nothing about the outcome can be adjusted: it was fixed at the commit step.
- Reveal. After the round, the seed is revealed. Hash it yourself and compare with the published commit — a match proves the result existed before your bet.
Step 1
Seed
The server fixes the round’s outcome as a secret seed.
Step 2
Hash published
Only the seed’s hash is shown before betting opens. It pins the result without revealing it.
Step 3
You play
Bets and cash-outs happen. The outcome can no longer change.
Step 4
Seed revealed
Hash the revealed seed yourself. Same hash = the result was fixed in advance.
A worked example
An illustrative round, using SHA-256 as the hash function. You can repeat the check with any SHA-256 tool.
Before the round — published hash
dde93053e586c455f19696d7299d3be462e363321c24b031074737f9009fcf22
After the round — revealed seed
turbo-demo-round-7f3a91
Your check
SHA-256("turbo-demo-round-7f3a91") = dde93053…9f009fcf22 ✔ match
If even one character of the seed changed after you bet, the hash would be completely different — that is why a published hash cannot be quietly swapped for a better outcome.
What you can verify
- The crash point of any crash round — it was set before betting opened.
- The bomb layout of any mines round — committed before your first click.
- Any instant-game result — same commit-and-reveal scheme across the catalog.
Provably fair vs RTP
The two answer different questions. RTP (return to player, typically 95–97% across Turbo titles — each game page lists its exact figure) describes the long-run average. Provably fair guarantees each individual round was not manipulated. Turbo Games gives you both: published RTP per game, verifiable seed per round — on top of independent RNG certification by accredited labs.

Provably fair — FAQ
What does “provably fair” mean?
Provably fair is a cryptographic scheme that lets you verify a game result independently. The outcome is fixed and published as a hash before any bet is placed, so it cannot be changed mid-round, and the revealed seed afterwards proves it. Every Turbo Games title uses it.
How do I verify a Turbo Games round?
Take the seed hash the game published before the round (commit), then take the seed revealed after the round, hash it yourself, and compare. A match proves the result was fixed before you placed your bet — no hidden RNG, nothing adjusted mid-round.
Can the game change the outcome after I bet?
No. The outcome is pinned at the commit step — before betting opens — so the crash point, bomb layout or spin result cannot be altered while you play. The post-round reveal lets you confirm it.
Is provably fair the same as RTP?
No — they answer different questions. RTP (95–97% across Turbo titles) is the long-run average return. Provably fair guarantees each individual round was not manipulated. Turbo Games gives both, plus independent RNG certification by accredited labs.
Which Turbo Games titles are provably fair?
All of them — the same commit-and-reveal scheme runs across the whole catalog: crash, mines, vortex, cricket, tower and every instant title. Each game page also lists its exact RTP.
