Is this prime?
It had to be done:<p><pre><code>    setInterval(function() {
      var n = parseInt(document.querySelector("#n").textContent);
      document.querySelector(is_prime(n) === "prime" ? "#yes" : "#no").click();
    }, 0);
    
    document.querySelector("#start").click();
</code></pre>
EDIT: replaced my isPrime with the one already in the game.<p>EDIT 2: There appears to be some sort of increasing delay (pretty sure it's not just `is_prime` being slow) starting around 500 points. Maybe the game itself trying to compute primes?
