| | 12 | .Sh DESCRIPTION |
| | 13 | This program allows you to play the familiar Battleships game against the |
| | 14 | computer on a 10x10 board. |
| | 15 | The interface is visual and largely self-explanatory; |
| | 16 | you place your ships and pick your shots by moving the |
| | 17 | cursor around the |
| | 18 | .Sq sea |
| | 19 | with the |
| | 20 | .Xr rogue 6 |
| | 21 | / |
| | 22 | .Xr hack 6 |
| | 23 | motion keys |
| | 24 | .Dq hjklyubn . |
| | 25 | .Pp |
| | 26 | Note that when selecting a ship to place, you must type the capital letter |
| | 27 | (these are, after all, capital ships). |
| | 28 | During ship placement, the `r' command may be used to ignore the current |
| | 29 | position and randomly place your currently selected ship. |
| | 30 | The `R' command will place all remaining ships randomly. |
| | 31 | The \&^L command (form feed, ASCII 12) will force a screen redraw). |
| | 32 | .Pp |
| | 33 | The command-line arguments control game modes. |

| | 39 | .It Fl s |
| | 40 | selects a |
| | 41 | .Dq salvo |
| | 42 | variant |
| | 43 | .It Fl c |
| | 44 | permits ships to be placed adjacently |
| | 45 | .El |
| | 46 | .Pp |
| | 47 | The |
| | 48 | .Dq blitz |
| | 49 | variant allows a side to shoot for as long as it continues to score hits. |
| | 50 | .Pp |
| | 51 | The |
| | 52 | .Dq salvo |
| | 53 | game allows a player one shot per turn for each of his/her ships still afloat. |
| | 54 | This puts a premium scoring hits early and knocking out some |
| | 55 | ships and also makes much harder the situation where you face a superior force |
| | 56 | with only your PT-boat. |
| | 57 | .Pp |
| | 58 | Normally, ships must be separated by at least one square of open water. |
| | 59 | The |
| | 60 | .Fl c |
| | 61 | option disables this check and allows them to close-pack. |
| | 62 | .Pp |
| | 63 | The algorithm the computer uses once it has found a ship to sink is provably |
| | 64 | optimal. |
| | 65 | The dispersion criterion for the random-fire algorithm may not be. |
