Archipelago's gameplay is astonishingly straightforward: Tap an island controlled by your forces to select it, and then tap an enemy A.I. island to send your troops there. Half of an island's available troops participate in the attack; the other half say behind to defend the island. To take over an enemy island you must overwhelm the island with more troops than they have currently defending. It may take several attack waves to capture the island!
The best strategy may include capturing a neutral (grey) island. Large islands can station more troops, and your forces will grow faster. You can send an attack wave from multiple islands. Drag your finger across the screen to select the islands you wish to have participate in the attack.
Archipelago can be played with more than on A.I. player and includes Campaign and Single Game modes. In Campaign Mode, you will always control the blue player, and you have no allies. In Single Game mode, you can configure teams as you desire using seven colors and up to four teams.
