Grind Islands: Idle War

Build, battle, and conquer a world of islands — an idle war strategy where your empire keeps growing even while you're away.

Grind Islands is an idle war strategy game about building island colonies and conquering the seas. Raise forts, barracks, towers, and workshops, train your army, and send it into battle to capture enemy islands one by one.

Your colonies keep working and earning while you're offline — come back to stacked gold, a stronger army, and new islands ready to claim. Upgrade a deep skill tree, unlock powerful boosters, cast battle magic, and fight your way through three story acts up to the final boss.
