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 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
Once you choose COM you will see a game setup menu. Here you can adjust difficulty, board size, handicap, and more. The options are as follows:
 * 対局相手: Here you can choose one of four difficulty levels for the computer.
 * 弱い: Very easy
 * ??: Easy
 * 強い: Intermediate
 * ??: Hard
 * 碁盤の大きさ: Go Board Size; you may choose 9x9, 13x13, or 19x19
 * 互先: Even game; there is no handicap.
