Python Dice Game/Need help with my script/looping!

[Constantin Sorin]

Hello,I recently started to make a dice game in python.Everything was nice and beautiful,until now.My problem is that when I try to play and I win or lost or it's equal next time it will continue only with that.
Exemple:
Enter name >> Sorin
Money = 2
Bet >> 2
You won!
Money 4
Bet >> 2
You won!
and it loops like this :/

Here is the code:

import time
import os
import random
os = os.system
os("clear")

print "What is your name?"
name = raw_input(">>")

def lost():
	print "Yoy lost the game!Wanna Play again?Y/N"
	ch = raw_input(">>")
	if ch == "Y":
		game()
	elif ch == "N":
		exit()



def game():
	os("clear")
	a = random.randint(1,6)
	b = random.randint(1,6)
	c = random.randint(1,6)
	d = random.randint(1,6)
	e = a + b
	f = c + d
	money = 2
	while money > 0:
		print "Welcome to FireDice %s!" %name
		print "Your money: %s$" %money
		print "How much do you bet?"
		bet = input(">>")
		if e > f:
			print "you won!"
			money = money + bet
		elif e < f:
			print "you lost"
			money = money - bet
		else:
			print "?"

		print money
	lost()	

game()
