Achievements and more...

Version 1.2.2 is online:

- Added achievements
- Updated the map to contain two secrets you can find
- Fixed a bug that allowed skipping 4 puzzles near the end of the game
- Added a higher resolution character set table for 1080p and bigger displays
- Added a safe-mode launch option for players who had problems launching the game
- Minor spelling fixes in the level descriptions

If you started a game before this release and want to get the achievements, you need to start a new game, because the achievement checkpoints are saved inside the savefile and the old versions had none.

Safe Mode Note: While achievements will work, they won't be uploaded to Steam in safe mode. The achievements will register and will be saved to your local disk, but won't be uploaded to Steam.

Update (Feb 11) version 1.2.3:

- improved saving speed
- pressing F4 in level editor moves the player out from registers so you cannot get stuck while editing levels

Level editor

Version 1.1.7 is online with the Level Editor feature where you can create new levels and even play levels from other players. If you create some nice levels and you would like to share those with other players, please follow the instructions on the level editor screen to send me the level and I will add it to the game so that everyone can play it.

Depending on how many levels get sent I might add more features like previewing levels with screenshots and custom names or descriptions. Maybe even direct integration with Steam Workshop.

Have fun creating new adventures for our Rogue Bit!

About This Game

You play the game as a single bit of computer memory. You can invade other bytes around you and thus modify their values.

The game features various types of puzzles:


With ability to XOR into adjacent bytes, you can navigate your way through existing data in the memory. The game automatically marks the bytes you cannot go through without getting yourself overwritten and prevents you entering those. Both binary and ASCII views are available, which you can utilize to find an open path for a particular puzzle.

Decipher programs

Various programs run on the computer you are trying to escape from. The game includes a disassembler showing you the assembly language corresponding to the machine code that is being executed. Don't worry if you don't know any Assembly. There are only a handful of CPU instructions and they are introduced gradually as you complete the puzzles. Reading the assembly code, you can track the program logic, see which parts of RAM it reads and writes to and manipulate data in those locations to get the program to do what you want.

Invade CPU registers

The computer you are trying to escape has a simple CPU with a couple of registers. You can trick the CPU to load yourself into the registers and affect code execution or offload yourself into otherwise unreachable memory locations.


For some puzzles, it isn't enough to change the data in RAM or registers. You can also change the machine code to get the computer to do different things.


Carefully observe the bytes on the screen and what the CPU is doing. Sometimes you need to read the code in straightforward manner. Sometimes you need to work your way backwards: find the line of the code you want executed and then trace the code backwards to figure out how to trick the CPU to get to that instruction.

The game only has about 30 puzzles, but some of those might take considerable effort to solve. So take it easy and don't rush to the end. If you solve a puzzle by accident, don't go forward until you understand why it happened. You might miss some small detail and get completely stuck on the next puzzle.


The game is about the way computers work internally. This isn't a game about writing new programs, but hacking existing programs and their data to clear the path or teleport across memory until you find a way to escape the computer completely.

Having some programming knowledge makes the game easier, but it isn't required. All the elements required to solve the puzzles are explained in the game.
