Your objective is to conquer all opposing islands by sending your fleet to capture territory and defend your own base. Each island you control increases your gold income, which can be used to upgrade ships and improve your island defenses. Use your mouse or tap and swipe on touch devices to select your island and direct ships toward enemy or neutral islands. Quick decisions and precise targeting are key to winning. Progress by capturing more islands, earning gold, and unlocking new monuments and ship upgrades. Each victory brings you closer to total domination on the map. Strategize your attacks and defenses—timing and upgrade choices can make the difference between victory and defeat.
Focus on weak islands - Target islands with fewer defenses first for quick expansion. Upgrade ship speed - Faster ships let you attack and defend more efficiently. Balance offense and defense - Don’t leave your home island unprotected while attacking. Use gold wisely - Invest in both ship upgrades and training speed for optimal growth. Watch rival moves - Observe enemy fleets to anticipate attacks or weak points. Unlock monuments early - New monuments provide passive bonuses and cosmetic flair.
