Unsurprisingly, it's a clear plastic device that runs on batteries and comes with some super underwhelming built-in minigames. You won't be playing Grand Theft Auto V or even Sonic The Hedgehog 2 on this baby. No sane manufacturer would preload this with illegal game ROMs and ship it off to a state correctional facility, right?
The games on this console appear to have been made for it, or for earlier variations of it (which were "normal" and meant for the outside world, not just prisoners).
And, these games are indeed very basic time-killers that likely won't hold the attention of a grown adult for long, but are still probably better than nothing. They're looking as if they were made in the early 90s, the kind of games you'll see on a SEGA Genesis or GameGear. But there are plenty of them, though – shoot 'em ups, racing games, platformers, basic sudoku and card games… Lots to choose from, over 40 opportunities for disappointment!
