The game uses a top-down operational map divided into sea areas and turns. Players move task forces, search for opponents with aircraft, launch strikes, conduct surface engagements, and protect or attack objectives such as islands, convoys, and naval bases.

Each scenario defines forces, objectives, and a time limit. Aircraft availability, damage, fuel, weather, reconnaissance, and carrier positioning affect every decision. Victory is determined by scenario objectives and comparative losses rather than by simply destroying every enemy unit.

Reconnaissance is the foundation of a successful operation. Search widely before committing carriers, and avoid exposing a task force whose location is unknown to the opponent.

Keep carriers protected by screening ships, preserve reserve aircraft for defense, and coordinate strikes so that enemy carriers are attacked before they can launch effectively. Fuel and damaged aircraft limit later operations, so do not spend all available strength during the opening turns.

Use the scenario objectives as the main guide. A player can lose by chasing ships while neglecting airfields, convoys, or scheduled invasions.
