Not for beginners The setup only allows you to play against computer-controlled opponents or real opponents. Even the weakest computer-controlled opponent is far better than I am, so I get my clock cleaned every time.
Rules are easily accessible at any time, but since they're all in Japanese, it's difficult figuring out what you're being told.
The multi-player option is only available if you have someone nearby with the game, or if you own a DSi. Since I have neither, I can't say much about this option.
This game is definitely not for beginners.
