It's a janken (RPS) type game, where each round, if you win, the girl disrobes a little further. There's only a single girl, but a fair amount of art. Controls are Enter, Space, and the number pad keys (1,2,3) to chose what you want during the RPS. The game loads quite slowly on default settings, so be prepared for some lag. The game is not truly "random" but increasingly has the girl chose a counter to whatever hand you play the most.
