Battle of Kingdom

About

Battle of Kingdom is a Game Boy strategy title from 1991 where players guide a kingdom through a series of turn-based battles. Each stage functions like a grid-based board game with the goal of wiping out 92% of enemies to unlock the next fight. Progression follows a fantasy narrative where you and three other factions battle to control territories and ultimately assault a skull-shaped castle housing a mysterious threat. Combat relies on positioning and resource management with limited units and spells. The game stands out for its rigid difficulty curve and straightforward mechanics. The 92% kill requirement for each stage creates a distinctive challenge that tests efficiency over brute force. Its skeletal castle final boss and medieval fantasy setting feel surprisingly cohesive for a 1991 portable release. As one of the earliest Japanese-only Game Boy strategy games, it remains a niche artifact for retro handheld enthusiasts.
