ほくリバーシ is a puzzle game available on the Android platform. Developed by ほく, this game offers a unique twist on the classic game of Reversi. In this game, you can play against ほく君 (CPU), but be warned, losing the game will result in some surprising and colorful language from ほく君.

To avoid being berated, your only option is to win against ほく君. It's a puzzle game that motivates you to improve your skills and avoid becoming someone's "food" in the game. The game's AI is designed to become stronger as you play, making it a challenging and practical app for those who want to avoid being insulted.

Please note that while most players will find this app useful for improving their Reversi skills, it may have the opposite effect on those who enjoy being on the receiving end of insults.

Update: As of January 31, 2016, the game has added more colorful language to its repertoire. It was first released on April 10, 2011.
