Nothing happening after using while loop

I am currently trying to make rock, paper, scissors in the browser using only JS. I am using prompt and alert to tell the values but my program is not working after putting a while. Before the while loops, the alert function is working but after using while loop, nothing is happening. I don't know why. Here's my code->

const getRandom = (arr) => {
  return arr[Math.floor(Math.random() * arr.length)];
};

alert ("Welcome to stone,paper and scissors. you will play against the computer.You will have ten chances to prove your worth")

let chances = 0

const arr = ["stone", "paper", "scissors"]

let uwins = 1
let cwins = 1

while (chances <= 9) {
  let inp = prompt("Please enter the value")
  let rand = (getRandom(arr));
  if (inp == 'stone' && rand == 'scissor') {
    alert("you won")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
    ++uwins
  }
  else if (inp == 'stone' && rand == 'paper') {
    alert("you lost")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
    cwins += 1
  }
  else if (inp =='stone' && rand =='stone'){
    alert("its a tie!!")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
  }
  // ``````````````````````````````````````````````````````
  if (inp == 'paper' && rand == 'scissor') {
    alert("you lost")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
    cwins += 1
  }
  else if (inp == 'paper' && rand == 'paper') {
    alert("it a tire!!")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
  }
  else if (inp =='paper' && rand =='stone'){
    alert(" you won")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
    ++uwins
  }
    // ``````````````````````````````````````````````````````
  if (inp == 'scissor' && rand == 'scissor') {
    alert("it a tie!!")
    chances += 1
    alert(`You have ${chances} chances left`)
    console.log(rand)
    
  }

Please help
