great product for teachers and students who wants to learn English

My Kids love it.

This does seem like an interesting concept, however, this is the worst online interactive testing tool I have seen. One of my students saw a power-up selling for $210 (in-game money), and it would make all items free for 20 seconds. Now, when he bought it, this is what actually happened. He got all his money taken away, discovered it had no effect, and all his upgrades were destroyed. You, as a cruel joke, nearly got this child sent home to his strict parents who grounded him for a B+. But, he would have an F. You douchebags had a silly idea of "what would happen if we scammed children". But instead of making a new game, you decided to implement that into your STUDENT TESTING PROGRAM. You trashy idiots could have gotten that kid starved to death (his parents tried before over a D-, frick you CPS for not caring). This is spectacularly low quality. Do not use this program.

I have yet to find any serious flaws with Gimkit. It would be nice if, like Kahoot, you could use the free version, but that's completely not workable (you only get to make 4 question sets and can only edit each one three times), but hey, that's capitalism. It's pretty amazing that one day some high school kid was sitting through a Kahoot-type game and thought "I could make a better game" and then went and did it! I've developed digital games for my students in the past, and I'm kicking myself hard for not coming up with this first. >:-(
