Nine Hours Nine Persons Nine Doors is so compelling you will not be able to put it down until you have completed it, even then you will be longing for more. This has the most intriguing story-line of any game yet, easily out-doing the likes of the Phoenix Wright series, which have an amazing story-line, but 999 just blazes past it in caomparison. The expertly spellbound story-line will keep you well entertained, a deathly game with many great puzzles. The best thing about 999 is the amazingly tantalizing multiple endings, depending on how well you do in the game, all the endings are compelling. The characters are well suited, many that throughout the game you will learn to love.

9 Hours, 9 Persons, 9 Doors is, simply put, a brilliant visual novel. It combines an intense mystery, well written prose and simple gameplay to tell an incredible story. 
The story starts off hard and fast; You, as young Junpei, wake to find yourself locked in an unfamiliar cabin on an even more unfamiliar ship. The situation goes from confusing to perilous as water begins flooding into the cabin, forcing Junpei to franticaly search for a way out of the room, launching him into a adventure to escape the slowly sinking ship along with eight other captives.
The gameplay is split up between two distinct phases; narrative and escape. Narrative phases consist simply of reading the advancing story, occasionally making dialogue choices. The choices made during the narratives phases will determine which of the six possible endings your will achieve, focusing on which path you take through the ship. Thankfully, when replaying to acheive a new ending, you'll be able to fast-forward through previously read dialogue.
The escape phases involve using simple controls to navigate your way around the room you find yourself trapped in, collecting items and solving puzzles to escape. Be warned, as this game will challenge you with fiendish logic puzzles that may well leave you scrambling for a walkthrough. The only problem is, sometimes you'll have to resort to a bit of pixel hunting to advance.
The art in this game is fantastic and certainly proves that the visual novel genre is worth your time. The music is just as wonderful; sombre songs for emotional times, intense tunes for perilous puzzles and tricky ditties for perplexing mysteries.
If you're a fan of adventure games, visual novels or well-written mystery stories, 9 Hours, 9 Persons, 9 Doors is right up your alley and will leave you begging for more til the credits roll.
