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

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.
