My Take
Life will not always give you an easy time just because you answer right, other people will try and take you down. Personally, the goal is to keep going even if you are the lowest grade. Yes, you can steal from other people, people will get mad and angry and competitive. But it's supposed to create chaos and unity over this. I really enjoyed this too when playing with them or with other people because it gives people a sense of winning. "It's unfair to the kids because blah blah blah!" As someone who observes kids, they really like and and it makes them learn because, well, they want the point and they want to be first!
How I Use It
I used it for my grade 7 class, and they were really excited for it! They kept asking for more and more. I read one review of blooket "encouraging cheating and stealing" but that's the literal fun of the game?
