Le possible éditeur allemand trouvé par Forgenext n'a finalement pas donné suite.

En tout cas, ils ont fait des tests sérieux et un compte-rendu intéressant à exploiter (pour les anglophones ) :

We now had several testplays of Hexone and unfortunately came to
the conclusion that the game does not fit into our programme line.
The basic mechanics of the explosions (and several chains of explosions) and
the shrinking game board are appealing. But in our test plays, the game was
mostly over pretty soon. The starting player had a slight advantage and as
soon as a player had the majority on the board, the other player needed much
luck (meaning the leading player to make a mistake) to win. So in the end,
Hexone did not convince us.

Peut-être des modifications des règles à venir, peut-être une refonte de la mise en scène des mécanimses... Digestion d'abord...

Et encore merci à Forgenext !
