Cryptographic Proof
Verification Steps:
- Server seed committed before any entries
- Client seeds collected from all entries
- Combined seed used for random generation
- Results can be independently verified
Proof Status:
Run the full verification above to confirm the server seed, combined seed and winning numbers all line up. The buttons inside the technical details below also let you re-check each piece individually.

Verification Instructions
- Copy the Server Seed (revealed after draw), Draw ID, Nonce, and other commitment data from below.
-
Verify the Server Seed Commitment by computing:
SHA256("server_seed:" + draw_id + "|" + server_seed + "|" + nonce + "|" + entropy_sources + "|" + version + "|" + commitment_type)
Confirm it equals the Server Seed Commitment hash shown below. - Compute combined_seed = SHA256(server_seed + merkle_root).
-
Generate winning numbers using this exact algorithm:
seed_integer = combined_seed.to_i(16) # Convert hex to integer rng = Random.new(seed_integer) # Ruby's Mersenne Twister PRNG main_numbers = (1..MAIN_COUNT).to_a.sample(PICK_COUNT, random: rng).sort bonus_number = (1..BONUS_COUNT).to_a.sample(1, random: rng).firstGame config for this draw: MAIN_COUNT=40, PICK_COUNT=5, BONUS_COUNT=25 - Confirm the recomputed numbers exactly match the published result numbers.
