Armies of Gielinor is a turn based strategy game involving the interaction of units on a square grid. Players start with a Barbarian Chieftain, which is able to capture buildings, the most important being a nearby portal. Once a portal has been captured, the player is able to summon units using Mana. Units are used to fight the other players. Many units are aligned with a particular god, and require the player to have a suitably high favour to summon them. Favour is increased by summoning a unit of the highest level possible for that god. There are also neutral units, which can be summoned if the player has a high enough favour with any god, or by creating neutral units. The aim of the game is to fulfill one of three victory conditions, before any of the other players.
