What is wrong with this code (C++)

[The_Doctor]

For a peice of coursework for my uni course I have to make a simple game.

I not very experienced with C++.

There are 3 difficulty levels in it, each one inside a loop which will contain the rest of the game. In this code I am testing it to see if the loops work.

#include <iostream.h>

int main()
{
bool Easy;
bool Medium;
bool Hard;
int Option;

std::cout<< "Game intructions\n";
std::cout<< "Please select a difficulty level\n";
std::cout<< "1=Easy\n";
std::cout<< "2=Medium\n";
std::cout<< "3=Hard\n";
std::cout<< "4=Quit\n";
std::cin>> Option;

if (Option == 1) {
Easy = true;
}

if (Option == 2) {
Medium = true;
}

if (Option == 3) {
Hard = true;
}

if (Option == 4) {
return 0;
}

while (Easy == true);
{
cout<< "Easy test works\n";
Easy = false;
}

while (Medium == true);
{
cout<< "Medium test works\n";
Medium = false;
}

while (Hard == true);
{
cout<< "Hard test works\n";
Hard = false;
}
return 0;
}

When I press 1 nothing happens.
When I press 2 it says "Easy Test Works".
When I press 3 it says "Easy Test Works", then "Medium Test Works".
Pressing 4 does end the program.

I have no idea way this is happening.
