左下の表示数字、22→21の間違いですよね

2511-2520
今回の問題はどれもロジカルで美しくて解いていて楽しかったです。これぞカックロ。おかげでサクサク解けてしまってすぐ終わってしまいましたがw

ちなみにマッチ棒クイズはタップしても開けた事がありません。

Problem with #2492

I love the game but unless you fix the problem with 2492, I can’t advance!

Love it but small problem

The new puzzle 2492 is impossible to solve. It requires a sum of 23 in 7 digits but the absolute minimum of 7 digits is 28. Solving the puzzle for a sum of 28 works, it appears to be a typo.

継続して問題追加してるのは素晴らしい

楽しく遊んでますが、広告がイラつきます。カットつけてくれたら買います。1000円くらいまでなら買います。
最近の更新で、新しく追加する問題の得点の付け方が変わりましたか?
それまでの問題よりも低得点になりました。普通は難易度高いのでより高得点が出るようにするもんだと思います。

2026年1月追記
更新で問題番号が上二桁しか見れなくなりました。4桁の上二桁では特定の問題にたどり着くのは困難です。
改悪になってしまってるので戻して欲しいです。

2434番の左下の22横列が合計21になります。

2492番、真ん中の横7マスが23になってますが28の間違いです。横7マスでは23は作れません。
