# Creator: simulation and balance {#creator-simulation}

Simulation is conditional. Creator shows it only when the current game has a validated simulator with matching version identifiers. If confirmed absent, **Enable simulation** asks the modification agent to add and validate support.

## Configure a run {#configure}

Assign seats and policies, optionally shuffle roles, choose 1–5000 games, and set a reproducible seed. Available policies can include random, greedy, MCTS, custom, or a human seat. Start with a small batch before spending time on thousands of games.

## Read and replay results {#results-replay}

Results report win rates, draws or truncation, game length, first-player advantage, optional scores, and terminal outcomes. Open a sampled exact board and use play, pause, next move, speed, Take a seat, or Fork when supported. These numbers describe the simulator, not every human strategy.

## History and compatibility {#history-compatibility}

Refresh, reopen, compare, and download previous runs as JSON plus Markdown. Version guards keep incompatible results viewable but stop misleading replay. A rules/simulator mismatch is explicit; update and validate simulation before comparing again. See [Troubleshooting](/docs/en/troubleshooting/#simulation-recovery).
