My guess is that "." is not in your path. It
usually isn't for the root
login. Try typing ./tetris or ./trek from the /usr/games directory.
Most likely the above is the problem you're having. However, before you jump
to add "." to your environment variable PATH in your login script...
remember thats a security issue. You usually want to be very careful that
you're running the system copy of vi for example, and not an executable that
some miscreant has renamed from "rm" to "vi".
