The Games
The Cubedex of Boxes and Lines contains seven puzzles pretending to be arcade games, each on its own face of the cube:Tennis
It seems familiar, though you're pretty sure the original wasn't single player.
Box Breaker
You've seen this one before, too. There's definitely some sort of glitch in the display hardware.
Space Rocks
Another one you've seen a thousand times before. Where did the arcade even get these boards?
Food Guy
It kind of looks like this might be a bootleg board in an original cabinet. The ghost movement is way too easy, but the extra wrap-around paths are nice.
Road Agent
Action-packed driving action! Did I mention the action?
Z-Prix
Is this an arcade port of the console original?
Meta
Looks like you might need to fix this one before it does anything.
The Series
Jim McCann / TCHOW llc developed the Cube* puzzle games to continue his tradition of creating midwinter puzzle hunts for his brother. The Steam releases are the first time these tiny and frustrating puzzling worlds have been available to a large audience, and contain significant enhancements relative to their original (single-member-audience) releases.
The Cubedex of Boxes and Lines is the second game in the main series of Cube* puzzle games. It was created as a midwinter gift in 2016 and updated and polished for Steam in 2020.
The Standard Notes
Nothing in these store pages, the game web page, the game documentation, or other materials outside the game is a puzzle.
The Cubedex of Boxes and Lines is intended to be solved without decompilation, resource snooping, or modification of game files. Indeed, these are all considered cheating. (And, really, who are you cheating but yourself? Once you know the answer, you can never discover it fairly.)
You will, however, benefit greatly from scrap paper, a good reference for standard encoding schemes, and -- potentially, though it is not required -- the ability to write some small computer programs to search for solutions to combinatorial problems.
