Who doesn't love Kahoot?!? I give it a 5. I've used it for a few years, and the kids are always super excited when they find out we are doing one. They are easy to create and easy to find already created Kahoots that you can use. Kids can easily create them as well. Tried multiple times to get Jumble mode to work, and seems like they are still having some issues with it. But I like it, especially as a "blind kahoot" to introduce content. The kids can puzzle out the right answer even if they don't have a clue. It's not as fast paced and takes more time though.
