## What is Erwin?

Erwin is a sliding puzzle played on the six faces of a cube, a unique 3D experience with spatial audio and holographic depth effects.
Swipe to slide and merge tiles, or swipe the background to rotate the cube and work the other sides.
Tiles have a value that doubles when they merge, and each merge adds to your score.

Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values, some entangled and move together, and some even teleport.

Play together with friends via Game Center Multiplayer: take turns on a shared cube, watch each other's moves in real time, and climb the cooperative leaderboard.

Universal purchase with Family sharing: pay once, and play Erwin on iPhone, iPad, and Mac, with up to six family members. Erwin respects your privacy and your wallet. This is an app I wanted for myself without compromise or dark patterns: pay once and it's yours, on all your devices, with no ads, no nagging in-app purchases, no tracking, no profiling.

### 1/5 — Jeu

*2026-07-09*

Bonjour, pouvez-vous me dire quand est-ce que ce jeu sera complètement accessible avec VoiceOver car quand on fait glisser les tuiles pour construire le cube, il est impossible d’entendre les chiffres affiché à l’écran donc c’est un peu gênant pour les personnes déficients visuels donc s’il vous plaît est-ce qu’il serait possible d’arranger ce problème dès la future mise à jour. Merci. Merci pour la mise à jour de ce jeu qui a été corrigé avec succès. Dommage qu’on ne puisse pas entendre la forme des cubes. Exemple l’losange carré triangle etc. à l’écran y aura d’autres y aura-t-il d’autres mises à jour à l’avenir à propos de ce sujet Nathalie

**Developer response:** Nathalie, merci pour votre avis. La version 1.3.2 est maintenant disponible, avec une meilleure prise en charge de VoiceOver :

1) La face active du cube, au centre de l'écran, est désormais une grille VoiceOver : touchez-la pour entendre la valeur et la position de chaque tuile.

2) Balayez avec trois doigts sur la grille pour faire glisser les tuiles. Erwin annonce le résultat de chaque mouvement : fusions, points, votre score, ainsi que la valeur et la position des nouvelles tuiles.

3) Touchez l'écran en dehors du cube, puis balayez avec trois doigts pour le faire tourner. Erwin annonce quelle face est active et combien de tuiles elle contient.

4) Touchez le score, en haut à gauche, pour entendre votre score et votre record. Touchez-le deux fois pour entendre toutes les tuiles de la face active, ligne par ligne.

Si vous rencontrez un problème de jouabilité avec VoiceOver, écrivez-moi à info@erwin-game.com et je ferai de mon mieux pour le corriger.

////// 2026-07-11: Nathalie, merci d'avoir confirmé que la mise à jour fonctionne pour vous. Oui, d'autres améliorations d'accessibilité arrivent : une prochaine mise à jour étendra la prise en charge de VoiceOver au mode Multijoueur, pour que vous puissiez jouer à Erwin avec des amis. J'intégrerai aussi votre suggestion : les marques des tuiles deviendront audibles elles aussi, pas seulement leurs valeurs. Les marques, par valeur : 2 est lisse, 4 porte un carré arrondi, 8 un triangle, 16 un losange, et 32 un double cercle. Ces cinq formes constituent l'ensemble complet.
