I’m currently working my way through the various options for learning how to code via Swift Playgrounds, and branched out recently to the standalone session that lets you adapt a version of the well known game Rock Paper Scissors.
The demo first lets you play the game so you can see how it works, then it asks you to personalise the game with a variety of options. I think it wants you to pick the colours that each player uses and perhaps adjust the hue of the background, but I went for a slightly more ambitious personalisation scheme.
Rock Paper Scissors Lizard Spock. Sheldon would be proud.
