Recompute the result
Open any round from Rocketshot history and these fields are filled automatically. You can also paste disclosed values manually.
Provably fair
Proof before launch. Evidence after landing.
Rocketshot commits to a complete chain of outcomes before play. Once a round ends, its seed is disclosed so your browser can independently recompute the exact shot-down multiplier.

Rocketshot plays a SHA-256 seed chain backwards. Hashing this round’s seed must produce the preceding disclosed seed—or the commitment at the edge of the chain.
Current outcome chain
The active commitment and salt are public. Finished chains remain available so older rounds can still be checked.

The revealed data reproduces the recorded round.
A successful calculation shows that the disclosed seed and public salt produce the result Rocketshot recorded. The chain-link check shows that seed belongs to the commitment published before those rounds were played.
How Rocketshot derives a multiplier
HMAC_SHA256(seed, salt) produces the same digest for anyone using the disclosed inputs.
The first 13 hexadecimal characters become X = h / 2⁵², with 0 ≤ X < 1.
result = max(1.00, floor(99 / (1 − X)) / 100). This produces a 1% mathematical house edge.
