In the two-player card game Hordes of Grimoor, each player commands a Horde of Cohorts, trying to expand his Domain in the world of Grimoor. Players draw and play Cohort cards to strengthen their Horde and conquer new Territories. Territories can be built into Strongholds. Rare Curios grant the players scalable powers and points. At the end of three Conflicts, the player with the most points wins! Hordes of Grimoor uses a simple two Action turn system. Players alternate turns, with each player receiving two Actions which he must use to escalate the Conflict. Once a player has five Cohorts in his Horde, the Conflict ends and a new Conflict begins. After three Conflicts, the game ends and the player with the highest score wins!
