## Description
_PlayOnline Viewer_ is an online portal for Square Enix games such as Final
Fantasy XI. The Windows version is available through download and, like the
console versions, is included with each release of _Final Fantasy XI_ and its
compilations.
_Tetra Master_ , the card mini-game from Final Fantasy IX got a stand-alone
release as part of PlayOnline. It was included with many _Final Fantasy XI_
releases and cost 1$ per month to play. The services for Tetra Master stopped
on December 31, 2010.
Each card represents a character, monster or item from the _Final Fantasy_
franchise. They have arrows that may be on any of the four sides or corners of
the card, and a four-digits stat. value (Power, Type, Physical and Magical
defenses). The arrows point in directions in which the card can have effect.
If it is stronger than the cards it points to, these will be taken-over and
turn into the same color as the attacking card (one of the two player’s
color). Combos can be made by having multiple take-overs happen. The winner is
the player who owns the most card once the playing grid is full.
