Grugnetto's Naval Battle

How to play

1. Find and sink every ship in the opposing fleet before the computer finds yours.
2. Place your fleet, then take turns choosing grid cells to fire at; the selected AI level changes the opponent behavior.
3. Use the external host's game menu for detailed rules and any restart or save options.

Make your move

• Use the pointer to place ships and select a target cell. The host's game menu explains placement and turn rules.
• Check the host's Help or Controls guide for every key and touch action.
• Denny Games has not verified a complete external game session or device compatibility.

A small head start

• Spread your searches instead of firing repeatedly into the same small area.
• Read the host's controls and rules before starting a longer run.
