Getting a Highscore in Kuku Kube
Javascript (Cheating), Score = limitless?

I realized that the game timer was using setInterval, which is a very unreliable way of keeping time.  With that in mind, since js is single threaded, if we simply hog the thread, the timer can't update.  As a result, you can essentially get any score you want.  If you perform 1000 clicks in a single function call without releasing the thread, you guarantee a score of at least 60000 (in fact I did this and got 180000).  This is obviously cheating because the game lasts longer than 60 seconds, though the game doesn't realize it.  For this reason, any js solution at all is really sort of cheating.  Though the time increase is minimal for code that completes quickly, you can still potentially delay the timer for as long as your code runs.

var factor = 1000;

function findAndClick() {
  var array = document.getElementById("box").children;

  for(var j = 0; j &lt; factor; j++){
      var one = array[0].style.cssText;
      var two = array[1].style.cssText;

      var color;
      if(one != two){
        color = array[2].style.cssText;
      } else {
        color = one;
      }

      for (var i=0; i &lt; array.length; i++) {
        if (array[i].style.cssText != color) {
          array[i].click();
          break;
        }
      }
    }
}
$(".play-btn").click();
setInterval(findAndClick, 0);


Javascript (REALLY Cheating), Score = limitless?

The game's object is actually global.  As a result, you can tweak various properties to your advantage.  The easiest of which is to just set your score to whatever you want it to be:

$(".play-btn").click();
Game.lv = 1000000;
