This "abuse" title uses colored text, a mouse interface, and high score saving. The only thing missing is timer routines, since it's a turn-based solitaire game. If anything, it's a diagnostic tool to see what your interpreter can handle.

The game itself takes about two minutes to play, putting it into the "coffee break" genre with high pick-up-and-play value - and with high score retention, it has high arcade replay value. My par is 3,000 points. I had exceeded 4,000 points once.
