For multiplayer in Ludo game development, the best approach is to integrate a real-time online platform like Photon or Unity Multiplayer. Photon allows players to connect over the internet, creating a smooth online experience for Ludo games. You will need to set up game rooms, synchronize player actions (such as dice rolls, moves), and implement matchmaking or room invitations. Networking concepts like client-server architecture are crucial, where the server manages game state and synchronization between clients. Be sure to account for network latency, so smooth gameplay is maintained. You can also develop a turn-based system, where players take turns rolling the dice and making moves, with each player's actions being synchronized across all devices.
