Kahoots are best played in a group environment such as a classroom or conference room, or even with the family in the living room—game displays on a split-screen, such as a smart TV, laptop, or interactive whiteboard.
You can also use screen-sharing tools, such as ads. One is Skype or Google Hangouts to engage players from other classes or other parts of the world. Players use their devices, whether smartphones, iPads, canoe, laptops, or desktop computers. It does not matter as long as they have a browser and a good internet connection.
