I discovered it by playing Limbs by Blaž Urban Gracar

Wow, great new logic puzzle I just discovered!

In this logic puzzle you have to choose nine unique numbers (1 through 9) so that each row and column has a sum of 9 or less.

Une énigme mathématique que j'ai bien aimé :

Bob , Alice et Tim décident de jouer au ping pong. Comme une partie n'implique que deux joueurs, ils décident que deux d'entre eux joueront un premier match, puis le perdant laissera sa place au joueur sur le banc, et ainsi de suite.
Bob joue 17 matchs, Alice 15 et Tim 10.
Qui a perdu le second match ?

A really nice logic puzzle for amateurs of maths & voting systems!

The hexatetraflexagon ! Awesome and easy to make !
