Here is a link to a Google Slides presentation that has the "Make a Game" activity that Jewelbots teaches at hackathons and events! (Game is also known as "Catch the Leprechaun").
It comes with details and tips in the speaker notes!
This presentation can be used as a reference to create more extended lessons since things like LEDs or library classes could be expanded on. You can also use this to duplicate the Jewelbots hackathon experience.
