info

All ruleset settings will always be passed, but ruleset-specific settings (e.g. under royale, squad) will only take effect when the associated ruleset is in effect. For example, in a standard game, the value for royale.shrinkEveryNTurns isn't used in the game rules, but your Battlesnake server can still read it.
