Glulxe is the authoritative interpreter for the Glulx interactive fiction VM, which is a 32-bit update of the older Z-Machine standard.

This program can play games ending with .ulx, .gblorb, .glb, .blorb, and .blb. glulxe needs only a terminal; the optional graphics in some Glulx games can be shown by using the package gargoyle-free instead.
