You, the commander, start by developing your base on an island with collecting flags, the foremost resources in Flag War. Then build cannons to attack and erect walls for defense. Meanwhile, when the sky turns dull, when the sea speaks purple, a boat spawns out of nowhere next to your island, on which stands a special guest, bringing magical and powerful crystals that can bolster your base. Eventually, fire to devastate your enemies on other islands and be the last man standing!

Cannons are not mere weapons, but the influence you can control. Walls are not metaphor of the pathetic, but a strategic plan of the achiever. Flag factories are not neglectable, but the foundation of every island. Being a fierce, yet exhausted, king for seconds cannot help you stand till the end; the key is to always get ready for attack and respond in kind.

Scattered throughout the realm are mysterious veins of crystals infused with magical energy. Those who possess enough flags can claim the crystals and harness their powers.
