Place your fleet, then take turns firing at a grid you cannot see. First to sink everything wins.
Three levels of opponent, from one that fires at random to one that hunts properly once it finds you.
Start by placing five ships on your ocean. Pick one from the row underneath, press R or the rotate button to turn it, and click a square to drop it.
When both fleets are down, take turns firing. Click a square on the target grid and you are told whether it was a hit or a miss.
A ship is sunk when every one of its squares has been hit, and the fleet list at the top shows which ones are gone.
Sink all five enemy ships before yours go down. The dice button will place your fleet for you if you would rather get straight to the shooting.
Yes, they can sit side by side. They just cannot overlap or hang off the edge of the grid.
No. It only knows what it has shot at. The hard level simply shoots in a pattern that cannot miss a ship, then follows up properly once it hits.
Not along the edges, which is where most people look last, and not all in one corner. Splitting them up makes a hunting opponent work much harder.
Five, four, three, three and two squares, which is the standard fleet.
Battleship started as a pencil and paper game before the First World War and became a plastic box in the 1960s, which is the version almost everyone remembers.
There is more strategy in it than its reputation suggests. Shooting in a diagonal pattern guarantees you find every ship in fewer shots than random fire, because no ship can hide in the gaps.
Once you hit something, work along the line rather than around it. The hard opponent does exactly that, which is why it finishes a fleet so quickly.
