Device 6 is a 2013 iOS release from Simogo, ostensibly a puzzle game, although “game” is a bit of a misnomer here. It could be called a visual novel or piece of interactive fiction. It is mainly text, enhanced by sound, music, images and formatting.
Mobile Game (Derogatory)
If you own a smart phone in 2026, there’s a good chance you’ve been exposed to the horrors of modern mobile games. The most popular games are boldly billed as “free to play,” but are typically riddled with ads or paid loot boxes, with micro-transaction systems and dark patterns designed with scientific precision to promote addiction and spending.
Companies like Zynga, King and Tencent spent more than a decade systematically enshittifying these ecosystems, and Apple and Google have largely turned a blind eye to it while taking a 30% cut of the revenues enabled by these practices.
Device 6 hails from a simpler time. Five years after the release of the original iPhone, ubiquitous touchscreens were still exciting technology. Most of us remembered the pain of texting on a 10-digit keypad. Mobile games were slowly expanding beyond Snake and Breakout clones.
The Nintendo Wii had introduced motion controls to the public at large, and Microsoft’s Kinect brought computer vision. Now we all had multi-functional supercomputers in our pockets, and touch interfaces that could morph to any shape. In certain circles, there was a feeling that mobile was the new frontier for experimental game design.
Device 6 feels a little like an artifact from an alternate universe, one where mobile games didn’t drown in an ocean of slop; one where the user is made to feel something more than the desire to play one more indistinguishable level or tap their credit card.
If I sound bitter, it’s only because I think we were cheated out of a more interesting, vibrant future. Device 6 is a game that manages to feel fresh and innovative despite being 13 years old.
Text as Physical Space
Device 6 starts with a face scan. (Fake, of course. phones didn’t have face recognition back then.) A scan line buzzes across the screen once, twice, and then you’re in, given a generic-sounding user name.
The intro credits sequence that follows provides cinematic weight. It’s James Bond by way of Archer, stylized 2D animation of a delivery truck moving toward its destination backed by a light bebop soundtrack.
Then:

The black-and-white picture of a radio within the arrow is layered with film grain and parallaxed as you scroll, giving it a sense of depth, like a a storybook with cutout windows that peer into the another world. The sound of the radio accompanies the picture, but it becomes muffled as you scroll, because the text takes you out of the room, into a hallway.
The text gives you only a phone-sized page or two of description, bristling with side-thoughts in italics and more windows into the world before bringing you to a stairway where the text itself
steps
down,
taking you
through
the house, the shape and formatting of the text bringing you into a physical space.
Then it tips onto its side, inviting you to rotate your device to read the long, narrow lines that take you down a hallway, expanding to fill the screen again only when you reach another room.
Device 6 presents as a multimedia House of Leaves: a trapped, semi-amnesiac character moving through a mysterious, empty island mansion as the text and pictures move across and around the page.

Reaching Through the Window
Device 6 is split into six chapters, each with a handful of puzzles that need to be solved to progress. These puzzles use text, audio, and visual components scattered across the chapter. Some of those storybook windows are interactive: locks, computer terminals, keypads and other machinery that can be pushed, poked, or manipulated.
Early chapters have fewer, more self-contained interactions and puzzles. Later ones tend to build on each other, requiring a cascade of solving one puzzle to solve another to solve another. Backtracking is at first helpful, and eventually mandatory, to find the necessary clues. This is where the format shines, because the layout of the story makes scouring the text feel like searching a physical space.
I found paper and pencil to be helpful in the last two chapters, but veteran puzzlers with good memory could probably make do without.

A Layered Labyrinth
There is layer of meta-narrative in Device 6 that is easy to ignore at first. The story and the puzzles are designed to immerse you in the viewpoint of Anna, the protagonist. You quickly forget about the face scan at the beginning.
In between chapters, the game asks a few survey questions, then awards points to the player. Never mind the strangeness of some of those questions. Never mind that nice round 100 points you seem to get no matter what answers you choose.
Each chapter features a diagram somewhere alongside the text; schematics for a series of numbered devices that work in tandem and directly affect the human brain.

Even the seemingly random elements that flash across the screen during the credits sequence have meaning, much more apparent upon finishing the story and going back for a second viewing.
These extra layers aren’t required to follow Anna’s story or solve the puzzles, but they provide connective tissue and help to interpret the otherwise ambiguous ending. They add a pinch of ARG flavor by making the reader feel like a character in the story.
Where to Play
Device 6 is $3.99 and should take about 1-3 hours depending on how quickly you solve the puzzles.
It is available on iOS, Nintendo Switch and Switch 2, and Windows. Do yourself a favor and play it on a device you can rotate and manipulate with your hands to get the full experience.
