The bet outcome is calculated by hashing today's secret with your Transaction ID.
You can check on your own by using the code and a past secret published here.

import hashlib
def xor_func(s1,s2):
   return ''.join(chr(ord(a) ^ ord(b)) for a,b in zip(s1,s2))
def verify(txid,secret,lessthan):
   sha512 = hashlib.sha512()
   sha512.update(xor_func(secret,txid))
   b = long(sha512.hexdigest(),16)
   result = b % 65537
   if result<lessthan:
      print "win!"
   else:
      print "lose!"
