  • Insult copy is funny and refreshing

    From 3 comments
    • The 'motivational' comments were hilarious and refreshing. I strongly disagree with the other advice you've been given here. Don't 'turn it up to 11' to remove all the subtlety…

    • I liked it, it made me smile. The standard "have-an-amazing-day" tone of sites submitted here is grating after a while.

  • Good for practising typing numbers

Objections

    From 3 comments

  • Client-side app is easy to cheat

    From 3 comments
    • It's staggeringly easy to hack because it's a fully client-side app but that's not really the point :)

  • Division and addition signs look alike

    From 1 comment
    • Sometimes it's hard to differentiate between the addition and the division sign. That's rather annoying.

  • No number pad makes it slow

    From 1 comment
    • Only if I had a keypad! Typing numbers in a mini keyboard is so slow.

Requests

  • Server-side scoring to prevent cheating

    From 1 comment
    • keeping questions captcha-like and calculating the score on server side, is one solution.

  • Sanitize leaderboard usernames

    From 1 comment
    • Just wanted to say that you should sanitize the leader board. Some of those usernames completely turn me off from the concept.

    • Cool little Game ! As a lot of people here, I threw together some JS to try and 'hack' the challenge. As mentioned by OP, this is "staggeringly" easy to do. Yet, I was wondering…

    • This reminds me of Case Interview Math: https://www.caseinterview.com/math/home.php Try with "Estimation Math", "Random", and "Hard". A friend of mine told me about this website.…
