Spike Chunsoft released 999: 9 Hours, 9 Persons, 9 Doors on iOS this week, and the room escape thriller is fleeing onto iPads and iPhones in Japan. However, it's not a complete port of the DS game which came to North America in 2010. Spike Chunsoft chose to remove the puzzle gameplay on iOS, placing the focus on the story as a visual novel.

In the puzzles' stead, the iOS version offers a comic book-style presentation (see below) and a new flowchart, similar to the one in sequel Zero Escape: Virtue's Last Reward, that lets you jump to different points within the plot.

While the iOS version is currently Japan-only, 999 lead writer and director Kotaro Uchikoshi said on Twitter that he thinks an English version "will also be released by autumn." There's no official word from Spike Chunsoft as yet, but given how both 999 and Virtue's Last Reward made their way west, a successful breakout across the ocean looks promising.
