How do I restrict my kids' computing time (application based)?

Question

I came from this similar question: How do I restrict my kids' computing time?

But I want to define a weekly computing time (e.g. 3 hours) for a specific application and the days when it's allowed to use (e.g. saturday/sunday).

I basically want to allow the educational use of the pc any time and allow games only on weekends.

There is Little Brother that I recommend. https://github.com/marcus67/little_brother/blob/fb_configuration_gui/README.md

The installation is not difficult if you go through the readme page.
