Tetra Master is the optional card game in Final Fantasy IX . At first glance, it seems similar to Triple Triad — the card game from Final Fantasy VIII. And while you can develop a general intuition for how to win, especially if you have strong cards, after playing over a hundred matches, I had to admit something: just playing the game and reading all the in-game tutorials wasn’t enough to truly understand the rules. Eventually, I gave in and started looking things up to figure out what I was missing. The complete absence of any actual rules — whether in the game or the manual — left me utterly frustrated, which is what led me to write this article, illustrated in OCaml.

Just to be clear, my salty critique is aimed solely at the Tetra<br>Master card game . While I can fully understand (and even agree with)<br>some of the criticisms directed at the ninth entry in the series, I<br>personally enjoyed the game a lot — maybe out of nostalgia. And since<br>the card game isn't required to progress through the main story, it's<br>entirely possible to enjoy the game while carrying only a mild sense<br>of frustration at not grasping the intricate — and arguably<br>unguessable — mechanics of its ruleset.
Some people will probably find it pretty strange to revisit this game<br>more than 22 years after its European release... and honestly,<br>they’re not wrong! I have to admit, I find it quite amusing to try and<br>turn this website into a sort of dusty old library, filled with<br>useless knowledge.
Context
I discovered the Final<br>Fantasy series through<br>its seventh installment in the late ’90s, watching my cousin Thomas<br>play it with rapt attention. I was deeply impressed and quickly became<br>a big fan of the series for its atmosphere, music, and stories. That<br>said, being very young at the time and having only played<br>JRPGs<br>like Pokémon Red, I didn’t care much about game mechanics — which<br>might sound awful to you, as I was missing out on what truly makes a<br>video game a game — so I rarely read the tutorials and just<br>focused on progressing through the story.
Even though the Final Fantasy series — at least the entries released<br>in Europe at that time — isn’t known for being particularly<br>difficult, ignoring the understanding of systems like the<br>materia system in Final Fantasy VII<br>can make progressing through the adventure very challenging . And<br>yes, while Final Fantasy VI, VII, VIII, and IX have a similar<br>Skill Ceiling to<br>Pokémon Red and Blue, I have a feeling that the Skill<br>Floor for those three<br>Final Fantasy games is significantly higher.
Holding a fondness for these games I had never finished, years<br>later I decided to play them again with the goal of completing<br>them. At that time, as a programmer, my interest was focused on the<br>RPGMaker series — a toy software for<br>building RPGs that offers a programming interface to create original<br>systems and grants great customization freedom for advanced<br>users. Playing classics from the<br>genre seemed like a perfect way to learn!
Since JRPGs are often long games and I wasn’t playing like a<br>hardcore gamer, nearly 10 years later, after finishing FF6, FF7, and<br>FF8, my takeaway was clear: reading the tutorials and understanding<br>the various game mechanics makes the experience much easier . While<br>each of these entries has its own subtle complexities related more to<br>the Skill Ceiling, overall the games were quite simple — which isn’t<br>a criticism — and I was ready to dive into FF9 with confidence.
Simple, but not in every aspect
Like its predecessors, Final Fantasy IX isn’t a complicated game. The<br>mechanics are easy to grasp, and although battles can sometimes feel<br>slow-paced — and the<br>Trance<br>system can be frustrating if you’re coming from the previous two games<br>— it’s pretty clear how to be effective quickly. My frustration,<br>however, comes from the card game. Like its predecessor, the game<br>includes an ad-hoc system called Tetra Master , which is<br>introduced fairly early in the...
