# Game Technology

**Unity3D Game Engine**

emoji™ Marble Dash is built in Unity3D, enabling smooth cross-platform performance on mobile (iOS/Android) and PC (Windows/macOS). Unity’s rendering pipeline delivers the bright, playful look that fits the emoji™ brand, while keeping gameplay stable across a wide range of devices.

The engine handles everything on the client side: rendering, input, UI, and asset loading. Through Immutable’s Unity SDK, blockchain features integrate directly into the game without custom networking code, speeding up development and ensuring reliable on-chain interactions.

**Photon Quantum Multiplayer Physics**

Photon Quantum powers the game’s deterministic, server-authoritative physics. All Marble movement and collisions are calculated server-side, preventing manipulation and guaranteeing that every player races under identical conditions. This creates a fair, skill-based competitive environment.

**PlayFab Backend Services**

Microsoft’s PlayFab supports the platform’s backend needs, from account management and progression tracking to social features and cross-platform data syncing. All off-chain data is securely stored and managed through PlayFab.
