When I first saw Triventy, it reminded me of Kahoot! The students join with a game pin, the questions and answers are displayed, and it will generate a leaderboard. But then it reminded me of Quizizz since the questions and answers also appear on the student device and you can share Triventy via Google Classroom.
It does not seem to have the tracking ability (found both in Kahoot! And Quizizz)- I could only find a leaderboard at the end of the game. So if you are looking for data on a question by question basis- this is not the game for you.
But what is does have is the ability to have your students collaborate with you in creating the questions. You can share the link a variety of ways (including Google Classroom) and you moderator all questions before they go live.
Rather than use this as a formative assessment, Triventy would be good as a review.
