If you've never heard of the Simple series of DS games, allow me to bring you up to speed: They're simple games. Well, that was easy. Now that we're on the same page, we can note that two new titles in the successful franchise are headed towards Japan. The first one to hit is Simple DS Series Vol. 7: The Illust Puzzle & Suuji Puzzle. Oddly enough, the game that follows is Vol. 5: The Trump.

Though the IGN article provides no simple explanation as to why the volumes are being released in a strange order (it's possible that they just got the numbers wrong), it does mention some of the gameplay you can safely expect. The Illust & Suuji Puzzle is a variant of, you guessed it, Sudoku. There's just no escaping the onslaught of Sudoku, it seems. In fact, we may have to start calling it a "phenomenon", an unpleasant turn of events considering that we struggle on a daily basis to correctly spell big 'ole words like that.

The Trump, on the other hand, capitalizes on a different kind of phoneme entirely--card games! It's set to feature 17 different kinds of card-based activities, which should be more than enough to addict those with a fondness for aces and spades. Best of all, both Simple games will incorporate multiplayer support for up to 4 players. Won't someone please pick these up and release them in the West? At the right prices, we're sure they'd turn out to be quite a pheromone.
