Original Problems


2-3rd of January, 2017

A new feature – Likes!

Dear authors and visitors, I’m happy to welcome you on JF in the New Year 2017! Thinking about how much authors are interested in any feedback (well, the editor is interested in it too! 🙂 ), this year I’ve decided to add a “Like” button for JF’s publications. […]

  • (03.01) No.1180 – James Quah (#2; Quintessence).
  • (02.01) No.1179 – Michal Dragoun (hs#4.5).

Animated diagrams use Py2Web by Dmitri Turevski and WinChloe’s graphics.

All previously published problems you can find in the subsections of Original Problems menu on the top. The judges of JF-2017(I) and of Retro & PG problems 2017-2018 are not appointed yet.
