Provably fair · RTP 97%

Before any round the server commits to a chain of 10,000 seeds: each seed is the SHA-256 of the next one. We show each round's hash before betting opens and reveal the seed after the crash. Check that SHA-256(seed) equals the hash, and that SHA-256 of this seed equals the previous round's seed. RTP 97% (house edge 3%). Take h = the first 13 hex characters of HMAC-SHA256(key = seed, message = client seed) as an integer and e = 2⁵². Crash point = max(1, floor(100 × 0.97 × e / (e − h)) / 100). The chance of reaching any target t is 0.97 / t, so the expected return is 97% whatever you cash out at.
