Itsu Demo Doko Demo Dekiru Igo: AI Igo DS/Play

The "Play Mode" (対局 on the main menu; literally "a game of go") is the first option on the main menu and the area in which you'll likely spend most of your time. Here you can play a game of go with customizable settings against either another human or against the computer. There are only three options here, COM, 人間 (Human), and 戻る (Go back). Selecting either COM or Human will provide you with a submenu to get your game set up and ready to play. Go back will simply return to the main menu.

Vs. COM
Choosing COM will take you to a setup menu for a match against the computer. At it's hardest setting the computer is still only able to play at a low amateur level. Someone who has been playing go regularly for around six months would likely be able to beat the hardest setting with relative ease. Here in the COM menu you can adjust difficulty, board size, handicap, and more. The options are as follows:
 * 対局相手 - Computer Setting
