Yes. You can make their games public. In addition, you can share their games via Facebook, Twitter or email.
If your students are under the age of 13, it is advisable that their games be set to private for safety reasons, if they contain personally identifiable information about the students, such as images of their faces, or the name of their school and grade. If a game is set to private, it can still be shared via a link of the game, so parents, for example, can still have access to the game even if they’re not using the same device that the game was created on.
Only Pro account users have the privilege of choosing to make their games private, so if this is important to you, please check out this page for more info on becoming a Pro Ji Tap user.
