Although it's been around for a few years now, I find that I still use it at least monthly, because the format works so well. When it first came out, it appeared to be tailored for a school atmosphere, but I have personally found it to work well with adult learners. It invites a participatory learning experience with a small twist of competition. I work with adult learners of varying technological skills, and a benefit of Kahoot!'s design is it is relatively intuitive; and most participants only require a few minutes to become familiar with the platform (I recommend having one or two practice questions to help familiarize them to the concept). Kahoot! does require an internet connection, a screen projection (for all participants to view), and either mobile devices or computers for players to submit answers. I personally feel that Poll Everywhere or Socrative is better equipped for facilitating discussions via polls and surveys than Kahoot! is, but for quick, interactive gamification, I find Kahoot! to be an excellent resource.
