## Description
Somewhere, in a rectangular zone lives Tix, a hostile line-like being that
moves around erratically. It possesses several minions, called Sparx, which
move along the border of the rectangle. Stix, a diamond-shaped marker
controlled by the player, starts at the border as well. The player has the
objective of defeating Tix by claiming territories and trapping it before the
time limit is reached.
_Tix_ is essentially a Qix variant. Stix can move horizontally and vertically
inside the rectangle or along the borders. When it moves in the zone, it
leaves behind a line. Stix can change direction and use that line to enclose a
section of the rectangle, thus claiming it. Sparx can be entrapped in that
section as well. That will destroy them, but others will appear shortly
afterwards in order to replace them. Once Stix has claimed enough territory to
trap Tix itself (60%), the player can move onto the next level of the game.
Stix starts with three lives and loses one every time it is caught by either
Tix or the Sparx. Sometimes yellow letters pop up in the rectangle. If the
player manages to collect them all, an extra life is granted.
