Sjóorusta

Sjóorusta was a digital adaptation of the classic pen-and-paper game Battleship, where players strategically placed and guessed the locations of opponent's ships on a grid. Players would compete against the computer, aiming to sink all enemy vessels before theirs are destroyed. This title holds the distinction of being among the earliest Icelandic-developed video games, reflecting the nascent stage of the country's gaming industry during the mid-1980s.
