Karryn's Prison, developed by Remtairy, is a hardcore adult RPG game that offers an experience like no other. The game is set in a notoriously lenient prison that has just rioted, and the player takes on the role of Karryn, the new female Chief Warden. The game features an innovative battle system, light management aspects, and a focus on gangbangs. All sex scenes take place within the battle screen, and there are no visual novel style sex scenes in this game.

Karryn's Prison is not a game for the impatient or anyone who wants to come in for a quick fap. It is a game that rewards time spent on it to learn the game. Although not necessary for most people to have fun and get their money's worth out of the game, Karryn's Prison is a game that strongly rewards players who want to repeatedly reset the game through New Game Plus to try, tinker and play with different builds and choices. The game also features three difficulty modes and can be played using a keyboard, mouse plus keyboard, or a XInput game controller. Playtime ranges from 10 to 30+ hours for first playthrough, and 100 to 200+ hours if you want to see every ending and collect every Title including all the Titles from Challenge Runs.
