Rainbet is a crypto casino whose in-house Originals — including Mines, Plinko and Crash — run on a commit-reveal fairness mechanic, letting a player independently confirm a round's outcome was not altered after the bet was placed.
How Rainbet's fairness system works
The mechanic is the same commit-reveal process explained in full on our main provably fair verifier: a server seed is committed as a hash before you play, a client seed you control is combined with it, and a nonce increases with each bet. After play, or after you rotate seeds, the server seed is revealed and can be independently re-hashed.
This page does not repeat that explanation in full — it focuses on getting your own Rainbet account set up to actually use it.
Where seeds live in your account
Look for a fairness, seeds, or provably fair section inside account settings rather than on the game screen itself. The exact menu wording and location can shift between site updates, so we describe the general area rather than a fixed click path — check your own account's settings menu for the current label. Once you are in the right panel, you should see your current client seed, the current server seed's commitment hash, and the running nonce count.
If you cannot find it
Search your account help centre for 'fairness' or 'provably fair' before assuming the feature does not exist — on a crypto-native casino it is normally present, just not always in the same place as the deposit or withdrawal screens.
Setting your own client seed
A client seed left on its default value is still verifiable, but it means every input to the result came from the operator's side. Setting your own value — even something simple — means the final result depends on a number only you chose, which is the entire reason the client seed exists as a separate field from the server seed.
Change it before a session you plan to verify, not mid-session. Rotating a client seed partway through can reset the nonce counter, which changes which bets you are able to cleanly re-check afterward.
Running the verification
Four steps, the same tool doing the actual hashing
- Note the server seed's commitment hash shown in your fairness panel before you start playing.
Where people trip up: This is the number you will compare the revealed seed against later — copy it somewhere safe rather than relying on memory.
- Play your session as normal on Mines, Plinko, Crash or any other Original.
Where people trip up: The nonce increases automatically; you do not need to track it manually for a basic check.
- Rotate to a new server seed when you are finished, which reveals the previous one.
Where people trip up: If rotation is not obvious in the panel, check your account help centre for the current wording used on the button.
- Paste the revealed seed and the commitment hash into the SHA-256 verifier.
Where people trip up: A match confirms the seed was fixed before your bets. Report a mismatch to support before trusting further results.
What this confirms, and what it does not
A matching hash confirms the server seed was not swapped after your bet. It does not confirm the house edge of the game you played, and it does not confirm anything about withdrawal speed, licensing, or account terms — see our Rainbet review for those. Full detail on what provably fair does and does not prove is on the main verifier page.
Licence, geo-restrictions and playing safely
Licensing. Access is blocked in a number of countries and US states, and the list is maintained by the operator rather than published as a stable document. The current restricted list and licence details live on the operator’s own terms page — read them before you register.
Your side of it. Crypto casinos settle fast, which is exactly what makes them easy to overplay. Before your first deposit at Rainbet, set a deposit cap and a session timer in the account settings — not in your head.
- Deposit limits and self-exclusion tools live in account settings, not support chat
- A losing session is not a signal to raise the stake — it is a signal to stop
- Bonus turnover targets are not a reason to keep playing past your limit

Frequently asked questions
Does Rainbet publish provably fair information for its Originals?
Rainbet's Originals — games like Mines, Plinko and Crash — are built on the commit-reveal mechanic that provably fair verification requires: a seed committed as a hash before play, revealed afterward for checking.
Where exactly do I find my seeds in a Rainbet account?
In a fairness or provably fair section of account settings, though the exact menu path can change with site updates, so it is not worth memorising. Look for wording like 'fairness', 'seeds' or 'provably fair' rather than a fixed click path.
Do I have to change my client seed before every session?
You do not have to, but setting your own value rather than leaving a default in place is the point of the client seed existing at all — it is the input you control in a process that otherwise relies entirely on the operator.
What do I do with a server seed once it is revealed?
Paste it, along with the commitment hash you were shown before play, into our provably fair verifier. It hashes the seed in your browser and tells you immediately whether it matches.
Does a successful verification mean Rainbet's games are profitable to play?
No. Verification confirms a result was not altered after your bet. It says nothing about the house edge of the game you played, which is a separate figure covered in our Rainbet games guide and the house edge explainer.
