Place, merge, and set sail
Choose ships from the shop and place them on the grid. Merge matching ships to make more firepower fit into fewer spaces.
Your fleet fights automatically after deployment. The formation you built and the coming tide shape the outcome, and you can trigger a fleet volley when the war drum is ready.
