❓Foire Aux Questions

Dépannage & Guides

💡Que faire si le jeu ne se charge pas, plante ou affiche un écran noir ?

Si un jeu ne démarre pas ou reste bloqué lors du chargement, cela est presque toujours dû au cache du navigateur obsolète. Effectuez un rechargement forcé (Ctrl+F5 sous Windows/Linux ou Cmd+Shift+R sur Mac) ou effacez le cache dans les paramètres de votre navigateur. Vérifiez également que l'accélération matérielle et WebGL 2.0 sont activés.

Is Slope 3D completely free and unblocked on school Chromebooks?

Yes. Slope 3D runs 100% client-side in WebGL with zero external ads, zero age gates, and no popups, making it perfect for school laptops.

Does it save my high score?

Yes. Your best run scores and session statistics are automatically saved locally in browser storage.
