Ludo Royale Case Study

Real Time Multiplayer with Photon PUN

The multiplayer layer is built on Photon PUN. Photon handles room creation, player matchmaking, turn syncing, and reconnection. Each move, dice roll, and token position is sent through Photon RPCs so every player sees the same board state at the same time.

Photon was chosen because it handles low latency turn based syncing well, scales for casual mobile games, and works smoothly across Android and iOS.

In Game Voice Chat

Players can talk to each other while playing. Voice chat is integrated directly into the match screen, so there is no need to open WhatsApp or Discord on the side. Voice runs on a WebRTC based real time SDK with echo cancellation and noise suppression so background noise stays low.

Each player has a mute button and a per player volume control. Voice chat works in all modes, including 1v1, 2v2, and 4 player matches.

Video Calling Inside the Match

Ludo Royale supports live video calling between players during a game. Player camera feeds appear as small tiles on the board screen, so you can see your friends react to a six or a sneaky knockout. Video uses adaptive bitrate, so it scales down on weak networks and stays usable.

Video can be turned off by any player at any time. The game keeps running normally if one player has video off and another has it on.

Text Chat with Photon Chat

For players who don't want to talk, Ludo Royale has full text chat through Photon Chat. Photon Chat handles message delivery, channels, and presence. There is a quick chat row with preset messages like "Good move" and "Nice one" for fast taps, plus a full keyboard chat for longer messages.

Profanity filtering and report options are built in to keep things clean.

Private Rooms with Room Codes

Any player can create a private room and share a short room code with friends. Friends enter the code and join straight into the same match. Private rooms support all game modes and all chat features. This is the most used mode by families and friend groups.

Hosts can set the mode, pick a board theme, and start when everyone is ready.

Multiple Game Modes

Ludo Royale supports four main modes. 1v1 for quick head to head matches. 2v2 for team play with paired tokens. Classic 4 player for the full traditional game. And private rooms where friends pick the rules. Quick match and ranked queues are available for public play.

Fair Play and Server Validated Moves

All dice rolls and moves are validated on a backend server. The client cannot fake a roll or move a token outside the rules. This stops common Ludo cheating tools that other games suffer from.

Customization

Players can pick from several board themes, dice skins, and token sets. Some are unlocked by playing matches, others by completing daily missions. None of the cosmetics affect gameplay.

Keeping Turns in Sync

In Ludo, every player needs to see the same dice roll and the same token positions at the exact same time. With four players on different networks, that's harder than it sounds. Lag spikes, dropped packets, and slow phones can all break the flow.

Running Video and a Game Together

Live video is heavy. It uses CPU, GPU, network, and battery. Running it next to a real time multiplayer game on a budget Android phone needed careful tuning so the game stayed smooth.

Stopping Cheaters

Ludo has a long history of cheat tools that fake dice rolls or skip turns. Any open client logic gets exploited fast.

Network Drops Mid Match

Mobile networks drop. Players walk into elevators, switch from Wi-Fi to 4G, or lose signal for 10 seconds. The game has to handle that without ending the match unfairly.

Voice and Video Quality on Weak Networks

Many players are on 4G with limited bandwidth. Pushing full HD video would kill the experience.

Photon PUN with State Reconciliation

Turn state is held by the server and synced through Photon RPCs. If a client falls behind, it pulls the latest state and catches up. This keeps all four players on the same board without visible glitches.

Adaptive Video and Voice

The video SDK drops resolution and frame rate when the network is weak. On very slow connections, video pauses and voice keeps working. Voice gets priority because losing the game's audio is worse than losing the picture.

Server Side Dice and Move Validation

Dice rolls are generated on the server, not the client. Every move is checked against the rules before it is accepted. Cheat tools that modify the local app simply have nothing to talk to.

Reconnect and Resume

If a player drops, the game pauses for a short window and lets them rejoin. Their tokens, turn order, and chat history all come back. Long disconnects fall back to an AI bot so the other players are not stuck waiting forever.

Lightweight Mobile Build

Asset bundles, texture compression, and Unity's IL2CPP build pipeline keep the install size small and the runtime fast on low end Android phones.
