ある程度強い人向け?

失敗になる理由が理解できません…

面白いのだが…

皆言ってるが日本棋院のアプリではお馴染みとなってる「どの様な失敗なのか説明しない」というスタイルは学習アプリとしては致命的な欠陥だと思う。これで囲碁嫌いになる人もいるんじゃないかな。

初心者向きではない

問題を間違えた時、「失敗」としか表示されず、理由が分からないまま次に進むので、ある程度の力がある人でないとストレスが溜まります。

ヨンロといっても

久しぶりにやったら、やり方をすっかり忘れてました。四路も容易ではありません。チャレンジモードを四苦八苦しながらも楽しんでます。

ヨンロかわいい

ヨンロが、とてもかわいいです。 登場キャラもいいですね。 こどもといっしょに遊んでいます。

これはなかなかいい

囲碁の入門的アプリを探していたのだけど、これは分かりやすくていいですね。

ムズイ

ヒント機能とかないの?
