3回の操作で可能な限り低い温度に設定せよ。
Set the lowest temperatures as possible in 3 times operations.


こんな感じでウェブリドル(web riddle)を沢山仕込んで、正解したら次のページに飛ぶようにする予定。

問題のヒントは、knifeのblog内のどこかに書かれていたり、必要に応じて自分で調べたりする。

いっそのこと、問題文すら提示しないほうがいいかなー。

とりあえず、HTML5とJavaScriptで操作はできるけど、次ページには飛ぶ様に変更してないから、いろいろいじってみて。

コメントやブログなどでヒントや答えを書くことはやめてね。
