Вы забыли вызвать функцию guessing. Нужно добавить строчку

guessing();

в конец тега <script>. Как-то так:

var user_guess; 
var random_number; 
var finished = false; 
 
function guessing() { 
  random_number = Math.floor(Math.random() * 100 + 1); 
  while (!finished) { 
    user_guess = prompt("I'm thinking of a number in a range from 1 to 100. Guess a number!"); 
    finished = checking(); 
  } 
} 
 
function checking() { 
  if (isNaN(user_guess)) { 
    alert("It is not a number! Write a number!"); 
    return false; 
  } 
  if ((user_guess < 1) || (user_guess > 100)) { 
    alert("It is not a correct number! Choose between 1 and 100! "); 
    return false; 
  } 
  if (user_guess > random_number) { 
    alert("It is higher than mine number!"); 
    return false; 
  } 
  if (user_guess < random_number) { 
    alert("It is lower than mine number!"); 
    return false; 
  } else { 
    alert("You got it!"); 
    return true; 
  } 
} 
 
guessing();

Добавь guessing();
