Jeu

Bonjour, pouvez-vous mettre ce jeu en français j’ai testé l’application For neuf mais j’ai constaté que quand on sélectionne des formes, l’application ne dit pas s’il y a conflit ou s’il y a des doublons donc on ne sait pas si on a placé les bonnes cases, on ne sait pas si on a corrigé les bonnes cases. Pouvez-vous si possible mettre l’application à jour en changeant ce problème? Merci. Nathalie

Response from developer

Bonjour Nathalie, merci beaucoup d'avoir essayé form9 ! Les conflits et les doublons sont bien signalés, et ces deux repères sont activés par défaut. Vous les trouverez dans Réglages (l'icône engrenage en haut à droite), puis Jeu : • « Afficher les erreurs » — une forme qui ne correspond pas à la solution s'affiche en rouge. • « Surligner les doublons » — les cases où la même forme apparaît deux fois dans une ligne, une colonne ou un bloc sont teintées en rouge. Si l'un des deux a été désactivé, il suffit de le rallumer. Un petit détail qui peut prêter à confusion : la case que vous venez de remplir reste sélectionnée, et la sélection masque la teinte rouge. Touchez une autre case et le doublon apparaît aussitôt. Pour toute autre remarque, vous pouvez nous écrire directement depuis l'application : Réglages ▸ Aide ▸ Nous contacter. Merci encore pour votre retour, form9
