This game is weird. I get the areas and how they work but it took me a long time. How common is is a game like this? I mean, am I likely to see something like this in December?
It is a weird game for sure. Zendu is a one of its kind game. There is no other game close to it in terms of its structure and peculiarity. That being said, the chances of seeing something like it are very low.
However, that does not mean the chances are zero. Case in point about weird old odd-ball games showing up again for a 'surprise! ambush you' repeat performance years after having been seen before. June 2003, Zephyr airlines game. It is also a rather peculiar game. Prior to June 2003 there was only one previous game like it, the fourth game in the October 1992 LG section, the lake with connected islands. It is weird with its structure and technically fits into the grouping category since you have to figure out which elements pair up together.
No game like the islands game had appeared again on a test since October 1992 so lots of people were thinking the islands game was just a one off fluke to never be seen again. Along came June 2003 and then whammo, Zephyr airlines jumped out of the graveyard and onto a test to pound people for a while. Zephyr is close to being a direct repeat of the islands game in terms of the logical structure. Nobody saw it coming and it really messed up test day and scores for a lot of people.
With that being said, you probably wont get a Zendu like game but you never know. LSAC has a bad habit of occasionally pulling an old dinosaur out of the dungeon, dusting it off, putting some clean clothes on it and then unleashing it upon test takers so it can terrorize them again.
