Is this prime? - Hackdot

Ah, you beat me to the minute (game comes with a function is_prime):

    var yes = document.getElementById('yes'),
        no = document.getElementById('no'),
        n = document.getElementById('n'),
        start = document.getElementById('start');


    function tick() {
        console.log('tick');
        if (is_prime(n.innerHTML) === 'prime') {
            yes.click();
        } else {
            no.click();
        }
        window.setTimeout(tick, 500);
    }

    start.click();
    tick();

Or, do away with the whole "checking" nonsense:

  game.check = function (answer) {
  	this.streak += 1;
  	this.next_n();
  }

  setInterval(function() {
    document.querySelector("#yes").click();
  }, 0);
  
  document.querySelector("#start").click();

(High score of 15,000!)

Why only add 1? Why add anything at all?

    game.check = function() {
        this.streak = Number.MAX_VALUE;
        this.next_n();
    };
  
    document.querySelector("#start").click();
    document.querySelector("#yes").click();

24607 (with the cheat), 621 (without) :D Fun evening challenge :P

  function isPrime(n){
    if ((n<=1) || (!n % 2)) {
      return false;
    }

  for (var k = 3; k < Math.round(Math.sqrt(n) + 0.5); k = k+2) {
      if (n % k == 0) {
        return false;
      }
    } 
    return true;
  }
  var nSpan = $("span#n")
  var yesButton = $("button#yes");
  var noButton = $("button#no");
  var body = $("body");
  function solve(){
    if (isPrime(parseInt(nSpan.innerHTML)) {
      yesButton.click();
    } else {
      noButton.click();
    }
    if (body.className != "end") {
      setTimeout(solve,0);
    }
  }
  solve();
