How the result is calculated
float[i] = HMAC_SHA256(server_seed, "client_seed:nonce:cursor"), 4 bytes per number 0 ≤ f < 1 roll = floor(float[0] × 10001) / 100 — a number from 0.00 to 100.00. “Under X” wins when roll < X, chance X%. “Over X” wins when roll > X, chance (100 − X)%. Multiplier = 99 / chance. Chance from 0.02% to 98%, multiplier from ×1.0102 to ×4,950. Bet up to $10,000 ÷ multiplier, at most $5,000.
How to play
- Set the target on the 0–100 track: drag the handle or type a number, chance or multiplier.
- Pick the winning side: “Under” is the left zone, “Over” the right one. You can also just tap a zone.
- “Roll” lands on a number from 0.00 to 100.00. Hit the green zone and you’re paid bet × multiplier.
“Raise after a loss” bumps the bet by the set percentage after every loss and resets it to the base bet after a win. If the next bet isn’t covered, we bet whatever is left. Off by default.
