My approach for Arrows 3 was slightly different but with the same conclusion. Sum of all numbers is 82. Corner arrows can point to up to 4 numbers, and middle arrows can point up to 3 numbers. The remaining off-corner arrows must therefore point to at least 3 numbers each (8x4 + 4x3 + 8x5 = 84, so we only have 2 to spare), so they must all go straight.

Interesting. Great to learn new approaches. Although I created with some particular idea, it turns out there are many other approaches to solve the same thing which even I am not aware of.
Thanks for sharing your approach.

Thanks for the test. When I saw the password with green word, I thought this test is the easiest part of the series. During the test, I approached all the puzzles assuming they are easy. It worked quite well :) Have you ever considered a non-Japanese ranking ? :)

Not surprisingly, nobody voted for arrows for "Which puzzle did you like most?" - all other puzzle types got at least one vote.
