Here ya go
" The "Nonary Game" is the game played by the characters in the 2009 Nintendo DS video game, 999: Nine Hours, Nine Persons, Nine Doors. Much of the game revolves around the number nine, hence the name."

Nona means 9 just like tri means 3 and octa means 8
The sequel is also another nonary game. Then they are making a third game that should be released sometime this year which is yet again another nonary game :3

Lets just say this is a game of life or death xD
lots and lots of reading though. (When you do your other play throughs you can skip all the dialog you've already experienced)
You have to play the game 6times for all endings.
(Trust me its different each time)
The ending you get is determined by which doors you go through during the game
and you only go through 3 each play through ^^

Its pretty addicting
