Clients propose actions, but the server authenticates the player, checks the game state and rules, commits valid moves, and sends each player only the information they are allowed to see. Clients handle input and presentation, then reconcile with the committed result.
What should the server own?
Model the game as a state machine. Its canonical state holds everything that is true about the match, including board positions, scores, turn information, deck contents or random state, and hidden information. A player’s move is a request to change that state—not proof that the change is legal.
For each action, the server checks the actor’s seat, the game’s current version, applicable deadlines, and the rules and invariants of the game. If the action is valid, it commits the next state and version. EigenInteractive’s design documentation describes separating game-defined state, actions, and observations from committed transitions. Unity’s chess example illustrates checking turns and moves, updating captures and end conditions, saving, and notifying players. These are patterns to adapt, not required cloud products.
Keep outcome-affecting decisions authoritative
The server should own turn order, deadlines, terminal results, and the canonical random sequence whenever they can affect an outcome. A deterministic transition function driven by a recorded seed and ordered actions can make debugging and replay practical. Not every game needs a permanent append-only event log, but decide explicitly what must survive a restart, how a match can be reconstructed or audited, and what happens if a write is interrupted.

What should the client do?
The client renders the board, gathers input, and presents feedback. It may calculate a rules-aware preview for responsiveness, but that preview must not become a second authority. Once the server responds, the client reconciles its display to the committed state or version.
Do not send a client information that its seat is not allowed to know. A preview based on hidden cards or other secret state can leak information even if the interface later masks it. The boardgame.io documentation describes optimistic updates and notes that optimism may need to be disabled for moves involving secret state.

Make connection and rejection states explicit
- While connecting, show a loading or waiting state rather than treating missing remote state as an empty game.
- When an action is rejected, keep the board aligned with the last authoritative observation and explain the rejection when useful.
- After a reconnect, replace or reconcile local state against the server’s current version rather than guessing which updates were missed.
How should a move be validated and committed?
A safe move path makes identity, game rules, and concurrency checks part of one deliberate flow. For a chess-like move, for example, the server—not the client—checks the source piece, destination, legal move, capture, and terminal conditions.
- Authenticate and bind the connection to a seat. A player ID supplied in an action is not proof that the caller owns that seat.
- Receive the game ID, action, and concurrency token. The token may be a state version or another explicit mechanism for identifying the state on which the request is based.
- Check access and eligibility. Confirm the game exists, the caller owns the seat, the game is active, any applicable deadline has not passed, and the request is based on a permitted version.
- Validate against canonical state. Apply the actual game rules and check all relevant invariants.
- Commit atomically. Write the new state and version together with any history record needed for recovery. Avoid a partial result in which the state changes but its version or required event does not.
- Build and publish observations. Generate the view each player is allowed to see, send the committed update, and provide a resume or notification path for disconnected players.
Prevent concurrent moves from overwriting each other
Choose a single ordering rule for requests affecting the same game. A serialized per-game room or actor, a transaction with a version comparison, or an equivalent mechanism can provide it. The essential guarantee is that two requests based on the same prior version cannot silently overwrite one another—or both be accepted when the rules allow only one.

One versioned state-machine design uses stale-version rejection, with a deliberate exception for simultaneous actions when the player’s observation has not changed. Use such an exception only when simultaneous play is part of the rules; it is not a general reason to accept stale moves. The cited EigenInteractive design uses a single serialized object per game as one way to order transitions, not as a requirement to use that technology.
How should hidden information, persistence, and recovery work?
Keep private facts on the authority
Maintain full canonical state on the trusted server, then compute a separate observation for each seat. In a card game, the canonical state may include every card’s identity while a player’s observation omits cards they are not entitled to see. Masking a value in the UI is not enough if the value has already been sent to the device.

Persist enough to resume and recover
Choose whether to store snapshots, ordered events, or both. A snapshot can make recovery faster; durable action history can support replay and investigation of disputes. Set retention and recovery behavior to fit the product. No single storage backend is required by these general patterns: Unity’s example uses Cloud Save, while the EigenInteractive design stores versioned transitions with the per-game authority.
Resume from a known version
On reconnect, send the client an authoritative current version and its permitted observation. If transition history is available, the service can send missed transitions or a snapshot followed by later transitions. The client should not infer its version from what it happens to have rendered. The EigenInteractive example describes cold connections receiving current state and clients recovering missed spans.

Which transport and services belong around the live game?
Choose transport for the pace of play
For a leisurely turn-based game, a reliable request/response API can handle actions and reads, with push notifications or polling to surface an opponent’s move. A persistent WebSocket can suit a game that benefits from immediate two-way updates or a continuously connected room. The cited examples use WebSockets or push, but do not establish one transport as best for every board game.
Separate the arbiter from supporting services
The live-game authority decides whether a move is legal and commits it. Identity, lobby discovery, matchmaking, profiles, leaderboards, notifications, and analytics can live in separate services or modules. Those services may maintain projections or read models that are briefly stale; they must not decide whether a live move is legal.
How do you choose an implementation?
Compare designs by the guarantees they provide for your game, not by product labels alone:
- Can each game have one unambiguous serialized authority, with safe handling of stale writes?
- Can the system produce a per-player view before transmitting state that includes secrets?
- How does it persist, resume, and, if needed, replay a match?
- How are reconnects and ordered updates handled?
- Does its operating model fit asynchronous turn-based play, rather than assuming a real-time simulation?
- Does it fit the team’s language, deployment, security, observability, and maintenance needs?
Examples illustrate different approaches rather than a neutral performance or price comparison. boardgame.io documents a remote game master, optimistic updates, WebSocket synchronization, and pluggable persistence; its default storage is in-memory, so a production game that needs durability must configure persistent storage. Colyseus describes authoritative rooms, server-defined synchronized state, matchmaking, and engine integrations. Unity’s Cloud Code chess example shows backend validation and persistence. None of these examples establishes a universal benchmark or the best choice for every team.
