Answers on a Postcard

(Published on 5. June 2025, 12:15 by IcyFruit)

Place a digit from 1-9 in each cell such that there are no repeats in any row, column, or box.

Cells separated by a knight's move may not contain the same digit.

Adjacent digits on a green line must differ by at least 5.

A digit in a red cell indicates the position of its column number within its row. For example, if R2C1 is a 3, then R2C3 is a 1.

I think I strained my forehead scrunching up my face trying to get the break in, but then it had a really fun and bouncy flow to it. Thank you for this!

One of the most unusual Icyfruit's puzzles I've seen, but certainly the solve path was no less engaging and fun overall :)

I am amazed that had a solution with so few clues. 16 minutes later I am no longer amazed but fulfilled. Thank you.

Absolutely amazing and surprising how this unfolds! Thank you very much for creating and sharing this lovely puzzle. And now I have to figure out why you chose this 6x9 grid…

Every time I'm one puzzle away from completing every IcyFruit puzzle, another one appears! What a gift, what a curse.

One day I'll get around to figuring out Taiga, but today I think I'll try this one.
