Hey, that's what I did too! In 4th grade we had this websites where you do some educational activities and it gives you raffle tickets. Then you play the raffle and you have a tiny chance of winning a prize (like a bracelet or a hoodie). I used to "hack" the number of raffle tickets I had and showed it to my friends. Then one of them told on me and the teachers said "Please don't mess with the websites."
