Play Tsumego Online

Tsumego was a Game Boy release from 1990, developed by Atelier Double. It arrived early in the handheld's life, a time when puzzle games were finding a solid foothold on the platform. The game presents itself as a digital adaptation of the classic Japanese board game Go, specifically focusing on life and death problems known as tsumego.

You do not control a character but instead place black and white stones on a small grid. Your objective is to solve each pre-set puzzle by finding the correct sequence of moves to kill a group of enemy stones or save your own. The core mechanics involve reading ahead several moves, visualizing the outcome of each placement, and understanding the rules of liberties and capture. The game progresses screen by screen through a series of these problems, with the difficulty ramping up steadily from basic captures to complex corner fights. It feels like a rigorous, satisfying mental workout where each solved puzzle provides a quiet sense of accomplishment.
