The ball drops and bounces left (L) or right (R) at each peg. The path is determined by HMAC-SHA512 hash using a special byte-to-float conversion.

Generate HMAC-SHA512(serverSeed, clientSeed:nonce)
For each pin (row), take 4 consecutive bytes from the hash
Convert 4 bytes to float: byte[0]/256 + byte[1]/256² + byte[2]/256³ + byte[3]/256⁴
If float ≤ 0.5, ball goes LEFT; if > 0.5, ball goes RIGHT
Final position = count of RIGHT moves
