Have the ability to copy numbers from one cell to the next (since deductive reasoning is so prevalent in this game)

I love this game, takes some time to solve but this is the beauty of it, making my heart peaceful. One function I wish it had was the number of sum is bigger or can be zoomed to see better.

Please add the ability to change the colors! The tan grid lines are very difficult to see. Like several other reviewers have mentioned, it would also be nice to be able to add all 9 notes to the blank cells at one time. Other than those two requests,I am very impressed with the app. It is fun, challenging, and works flawlessly!

広告が激増して、終わるのを待ってる間に寝落ちが増えたので。 そのうえ、再生トラブルで進めないことも多発し、さらには機能を減らす改悪も実行。 削除した時に、清々しました。 こちらはシステムに不慣れですが、今のところ不満はありません。 このまま楽しみたいと願うばかりです。

This is a good app, but we need to be able to tap once and drag across the notes number pad to add multiple numbers to a cell at once, rather than having to tap each number separately. As is, it's very inefficient and irritating.
