Deploy your five-ship fleet, then trade salvos with a CPU commander who hunts and targets your hull. Sink the whole enemy fleet before yours goes under. Runs entirely in your browser.
Setup: pick a ship in the list (or place them in order), hover/tap a cell to drop it, use Rotate to switch orientation. Battle: click an enemy cell to fire. ✳ = hit, • = miss, dark red = sunk.
