Lightbulb Education

Hi,

I am building a school app and one of the options is to have educational games on the phone embedded in the app. Need some free/open source codes for games such as Chess, Sudoku etc. and other possible games up to tenth grade for students in India.

If anyone has built a multiplayer framework which can be embedded, I would also be interested.

School has 1,000 plus students, but will not allow ads or secure information to be accessed either.

Do let me know if there are any options on this thread or message me in private.

Thanks
