Cashy Originals & Provably Fair: How to Verify Every Result (2026)
Cashy Originals are provably fair — you can cryptographically verify every result yourself. Here's how the server seed, client seed and nonce work, how to check a bet, and what provably fair does and doesn't guarantee.
Visit CashyCashy Originals are in-house games that are provably fair — you can cryptographically verify each result yourself instead of trusting the house. That's a meaningful trust feature, especially for a new brand. Here's how the seed-and-nonce system works, how to actually check a bet, and — just as important — what provably fair does not promise.
For the full brand picture, see the Cashy review or the Cashy data sheet.
What Cashy Originals are
Cashy Originals are games built in-house by Cashy rather than licensed from a third-party studio. They sit alongside the wider large multi-provider library — slots, table games, live casino and jackpots from established studios like Pragmatic Play, Evolution, NetEnt, Nolimit City, Hacksaw, Play'n GO and more.
The thing that sets the Originals apart is that they're provably fair: the outcome of each round is derived from cryptographic inputs you can inspect, so you don't have to take the result on faith.
How provably fair works
Provably-fair games use three ingredients per bet:
- Server seed — a secret value chosen by Cashy. Before you play, Cashy shows you a hashed version of it (a cryptographic fingerprint). Because a hash can't be reversed, this "commits" Cashy to that exact seed without revealing it yet.
- Client seed — a value from your side. You can usually change it, which guarantees Cashy can't have pre-computed the outcome around a seed only it controls.
- Nonce — a counter that increments with each bet, so every round produces a distinct result from the same seed pair.
When you finish (or rotate your seed), Cashy reveals the original server seed. You re-hash it and confirm it matches the fingerprint you were shown before betting. If it matches, the seed wasn't swapped after the fact — and you can recompute every result yourself.
How to verify a Cashy Original result
The general process, which is standard across provably-fair games:
- Note the hashed server seed shown before you play.
- Play your rounds, keeping (or noting) your client seed and the nonce for the bet you want to check.
- Reveal the server seed when you rotate it.
- Re-hash the revealed server seed and confirm it equals the earlier fingerprint.
- Recompute the outcome from the server seed, client seed and nonce using the game's published method, and confirm it matches the result you were given.
If step 4 and step 5 both check out, the result could not have been changed after your bet — that's the proof in "provably fair."
Visit CashyWhat provably fair does — and doesn't — guarantee
This is where honesty matters:
- It proves integrity, not better odds. Provably fair confirms a result wasn't tampered with. It does not change the house edge or make you more likely to win. Every game keeps its built-in margin, and the long-run expected outcome is still negative.
- It doesn't replace licensing. Verifiable results are one trust layer; the operator still needs to hold your funds and pay you. Cashy's licensing and payout record are covered in our is Cashy legit and safe guide.
- We don't publish RTP figures for the Originals. Cashy doesn't publish per-game return percentages we can verify, so we won't invent them. Treat the Originals as verifiable and provably fair, and check any stated RTP in the game itself before playing.
Originals vs the third-party library
Two different fairness models run side by side at Cashy:
- Cashy Originals use the seed-and-nonce provably-fair method above — you verify results yourself.
- Third-party games (Pragmatic Play, Evolution, NetEnt and the rest) use independent studio-level testing and certification of their RNGs and live products.
Both are legitimate; they just prove fairness in different ways.
Bottom line
Cashy Originals are provably fair — a genuine, checkable trust feature that lets you confirm each result yourself through the server seed, client seed and nonce. Just keep the honest framing in mind: it proves the game wasn't rigged, not that you'll win, and it doesn't stand in for licensing or a payout record. For those, and the full picture, start with the Cashy review and the is Cashy legit and safe guide.
