参考書としては悪くない

良い点

　全問正解するまで終わらないクイズで麻雀知識を叩き込める。

　解説パートが簡潔で隙間時間に読みやすい。

微妙な点

　対局パートの文字が小さくて読みづらい。特に自家を示す文字が小さい。自分が東家なのか北家なのか分かりづらいのは麻雀ゲームとしては致命的だ。


　解説パートの麻雀牌が一部ハテナになっている。断么と一盃口のパートで？になっていた。ハテナマークを見せつけた上で「この牌の組み合わせは断么になるか」と聞かれても適当に答えるしかない。

符計算を覚えるならこれ！

AIとの対局を楽しみながら符計算を覚えられるのがすごくいいです。実際の手牌で確認できるので、自然と符の考え方が身につきます。麻雀は打てるけど符計算は苦手、という人におすすめ。
