I couldn't resist the challenge...

It's not "real" Tetris but a variant called Xixit that I used to play a
lot on my 486. (I decided against Tetris because I had doubts about the
legal status of a reimplementation.)

I also have doubts whether it should be included in the demo suite: the
game logic is sufficiently complex that it begins to strain the limits
of gnuplot. Well, theoretically, we have conditional execution,
variables and eval in gnuplot, so it can do anything, but the point is
whether it is sensible to do so - and if someone said this example is
not sensible, I'd have to agree.

That said, it's playable and actually quite addictive.

Have fun,
