Game details

What is Island Siege about?

Island Siege is a turn-based strategy game where you fight to capture every island across a network of shipping lanes. Each island gains one troop per turn while your castle gains three, giving you stronger reinforcements to plan around. Sending troops empties an island completely and prevents both the sender and receiver from acting again that turn, so every move matters. Play the Island Siege game at Y8 now.
