How does Stake provably fair work?

Before each bet, Stake generates a server seed (hashed) and provides it to you. You contribute a client seed. The combination of these seeds, along with a nonce (bet number), determines the game outcome. After the game, Stake reveals the full server seed. You can then hash it yourself and verify it matches — confirming the result was predetermined and unaltered.

How do I verify a Stake game result?

In your Stake account, navigate to the fairness or game history section. Select any bet and click "Verify." You will see the server seed (revealed), client seed, nonce, and the resulting game output. You can manually hash the server seed to confirm it matches the hashed seed you were shown before the bet.

Which Stake games are provably fair?

All Stake Originals — including Crash, Dice, Limbo, Mines, Plinko, Keno, Blackjack, and Roulette — are provably fair. Third-party slot games and live casino games are not provably fair in the same way, but are audited by third-party testing agencies.

Can Stake manipulate provably fair results?

No. The system makes manipulation impossible because the server seed hash is shown to the player before the bet is placed. The actual seed cannot be changed without the hash changing — which you can detect. Neither Stake nor the player can predict or alter outcomes once the seeds are committed.

How Provably Fair Works on Stake

How Provably Fair Works — Step by Step

Step-by-step provably fair process on Stake.com
Step	Who Acts	What Happens
1	Stake	Generates a random server seed and hashes it using SHA-256
2	Stake → Player	The hashed server seed is shown to the player before the bet
3	Player	Player can set a custom client seed (or use the default)
4	System	Both seeds + nonce (bet number) are combined to generate the game outcome
5	Stake	After the bet, the full (unhashed) server seed is revealed
6	Player	Player hashes the revealed server seed and confirms it matches the original hash
7	Player	Player recalculates the game outcome using the seeds — confirms no manipulation

This system makes manipulation impossible because the hash commitment is made before the bet and cannot be changed without detection.
