How to Verify Stake Slide Results
Step 1: Get the Game Hash and Seed
After a Slide round ends on Stake.com, click on the game result to view details. The game hash and the seed (a Bitcoin block hash) are shown in the round's Fairness tab. Unlike other games, Slide uses a game hash system similar to Crash.
Step 2: Enter Both Values
Copy the game hash and seed into the form above. The game hash is unique to each round and is combined with the seed to generate the round's Slide multiplier. Make sure to copy both values exactly as shown.
Step 3: Compare the Slide Multiplier
The verifier will calculate the round's Slide multiplier using HMAC-SHA256 and display the result. The formula takes the first 8 hex characters, converts to decimal, and applies: max(1, (2^32 / (n + 1)) x 0.98), rounded down to 2 decimals. Compare this with the actual game result to confirm fairness. A bet wins if this multiplier reaches the target set before the round.
Frequently Asked Questions
How does Stake Slide calculate the round's multiplier?
Stake Slide generates an HMAC-SHA256 hash using the game hash as the key and the seed (a Bitcoin block hash) as the message. The first 8 hex characters (4 bytes) are converted to a decimal number. The final multiplier is calculated as: max(1, (2^32 / (decimal + 1)) x 0.98), rounded down to 2 decimals, where the 0.98 factor represents the 2% house edge.
What is the difference between Slide and Crash?
Slide and Crash use the same provably fair method: an HMAC-SHA256 of a game hash and a seed, turned into a multiplier by the same formula with a different house edge. They play differently. In Crash you cash out while the multiplier rises, before it crashes. In Slide you choose a target multiplier before the round starts, and you win if the round's multiplier reaches it. Slide has a 98% RTP and Crash a 99% RTP.
Why does Slide use a game hash instead of client seed?
Slide is a multiplayer game where all players share the same round result. Using a game hash ensures every bet in a round is settled against the same multiplier, whatever target each player set. The game hashes come from a chain Stake generates in advance, and only the chain's final hash is pre-committed. Each round's game hash is revealed after the round ends, and hashing it with SHA-256 gives the previous round's game hash, so no result can be changed after bets are placed. Publishing a game hash before its round would give the result away, because the seed is a public Bitcoin block hash.
Does this verifier work for both Stake.com and Stake.us?
It is built for Stake.com Slide. Stake.us Slide has its own chain of game hashes, and Stake's Stake.US Crash and Slide seeding thread (bitcointalk topic 5408287) announced its own seed, the Bitcoin block 747,460 hash. The only formula in that thread uses a 1% house edge, and Stake.us's Slide page has listed a 1% edge and, more recently, 2%. This verifier always applies Stake.com's 2% edge, so we have not confirmed that it reproduces Stake.us Slide results.
What is the maximum possible multiplier in Slide?
The theoretical maximum multiplier is 4,209,067,950.08x (2^32 x 0.98), which occurs when the first 8 hex characters of the HMAC are all zeros (00000000), a 1 in 4,294,967,296 chance per round. Most rounds land between 1x and 10x, with occasional higher multipliers. The minimum is always 1.00x.
Is my seed data safe with this verifier?
Absolutely. This verifier runs entirely in your browser using JavaScript. Your game hash and seed are never transmitted to any server. All cryptographic calculations happen locally on your device, ensuring complete privacy. You can even use this tool offline after loading the page.
