SugarCane is a site that allows you to create online games:
- Associating (think flash cards)
But rather than type in the content for each different game, you can create a data set and then use that data set to create a variety of games. All your games are public (and you can search by title). And to make things even easier, you can share via Google classroom! Don’t want to make your own game? Check out some of their samples.
