Craps游戏问题，忽略if语句

我目前所在的班级希望我制作一个骰子游戏。

问题出现在第二个while语句的int main中，该语句将点与滚动进行比较。它忽略if语句并再次执行循环，即使它达到了点或7。有时它会正常工作，有时它会重复循环几次。

#include "pch.h"
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int diceRoll() {
int x = 0, y = 0;
x = rand() % 6 + 1;
y = rand() % 6 + 1;
cout << "You rolled a " << x << " and a " << y << " which comes out to ------> " << x + y << " <-------" << endl;
return x + y;
}
bool playAgain() {
char ans;
cout << "Do you want to play again ?? Y to continue, N to quit." << endl;
cin >> ans;
while (ans != 'Y' || ans != 'y' || ans != 'n' || ans != 'N') {
if (ans == 'Y' || ans == 'y')
{
return true;
}
if (ans == 'N' || ans == 'n')
{
return false;
}       
cout << "Do you want to play again ?? Y to continue, N to quit." << endl;
cin >> ans;
}
}

int main()
{
srand(time(NULL));
int dices, bid, point = 0;
int money = 50;
bool gameRunning = true;
bool didTheyWin;
while (gameRunning == true) {
if (money == 0) {
cout << "You have no money, ending game." << endl;
break;
}
cout << "Please enter a bid. You currently have $" << money << endl;
cout << "$";
cin >> bid;
while (bid > money) {
cout << "Please bet below your current balance: $" << money << endl;
cout << "$";
cin >> bid;
}
dices = diceRoll();
didTheyWin = false;
if ((dices == 7) || (dices == 11)) {
cout << "You won $" << bid << " !" << endl;
money = money + bid;
}
else if ((dices == 2) || (dices == 3) || (dices == 12)) {
cout << "You LOSE! You lost $" << bid << " !" << endl;
money = money - bid;
}
else  {
point = dices;
cout << "The target number is > " << point << " <" << endl;
cout << "If you hit a 7 you lose, if you hit the target you win. nYou automatically roll until one of these two things happen.n";
while (didTheyWin == false) {
diceRoll();
dices = diceRoll();
if (dices == point) {
cout << "You won $" << bid << " !" << endl;
money = money + bid;
cout << "You now have $" << money << endl;
didTheyWin = true;
}
else if (dices == 7) {
cout << "You LOSE! You lost $" << bid << " !" << endl;
money = money - bid;
cout << "You now have $" << money << endl;
didTheyWin = true;
}
}
}
gameRunning = playAgain();
}
cout << "Thanks for playing. _END_" << endl;
return 0;
}
