Platform: MSX2
Publisher: Candy Side
Game: Guess the number
Difficulty: 1
Nudity: 4

In this brief doujin release, a schoolgirl is thinking of a number between 0 and 999, and you have to guess which. She drops hints at each guess as to whether your number is bigger or smaller than the one she is thinking of. When you guess correctly, she takes off an article of clothing, and the game ends when she is naked. Although it might seem kind of daunting, this game is incredibly easy; it gives you unlimited tries and doesn't penalize you for incorrect guesses.

* - This is probably not the correct title; the third kanji in the lower right corner is illegible. It's likely not even the title but instead the city in which the doujin circle was based; the disk introduced the game as merely "doujin soft".
