Cards Wars is a turn-based strategy game that combines Risk with the card game, War. You are presented with a map that consists of several provinces, each containing one or more cards. You control the red territories on the map. Attack neighboring territories and capture them by eliminating 50% of your opponent's cards. Each territory is allowed to attack or receive reinforcements once per turn. You can rearrange the cards on any of your captured territories to increase your chances of winning battles.
