Thanks a lot.
It doesn't work :(. I tested 3 proposals
log.info('Dernier jeu : ' + game.history[0]);
log.info('Dernier jeu : ' + JSON.stringify(game.history[0],null, 4));
log.info('Dernier jeu : ' + hdg.myBets[0].gameValue.gameValue);
I don't understand why we can get that value in CRASH game, but not for HASH DICE...
