How to play
Each player secretly places a fleet on a 10×10 grid (rows A–J, columns 1–10). Ships go straight across or straight down, never diagonally, never off the grid, never on top of each other.
| Ship | 1967 name | Squares |
|---|---|---|
| Carrier | Aircraft Carrier | 5 |
| Battleship | Battleship | 4 |
| Destroyer | Cruiser | 3 |
| Submarine | Submarine | 3 |
| Patrol Boat | Destroyer | 2 |
Take turns calling one square, like D-4. The other player answers miss or hit, and on a hit says which ship. When every square of a ship is hit, its owner announces it sank. Sink all five ships first to win.
Salvo
You call one shot for each of your ships still afloat: five to start, one fewer for each of your ships that has been sunk. The current box has you call them one at a time, hearing each answer; the 1967 box has you call them all at once, then hear the answers.
Other switches
Don’t name the ship (the box’s harder Salvo game): a hit is just “hit”; sinkings are still announced.
Ships can’t touch (a common house rule): no two ships side by side or corner to corner.
Rules in our own words. Every number and its source: rules check.
