The classic tetris game implemented in J. Fairly featureful:
- hjkl to move/rotate/drop faster.
- space to instant drop
- drop speed increases as score goes up
To run, just copy/paste one of the .j files into jconsole, (download here). I've only tested in 602; not sure if 701 will work.
There are three versions:
- tetris.j is the original, fairly clean version
- tetris.oneline.j is compacted to be a single (giant) function
- tetris.min.j is a semi-manually "minified" version that aims for compactness.
All should behave identically.
