User Summary Highgrounds is an original collectible card game with a twist. Each card represents a unit which you see on the battlefield. Each unit can be recruited using gold, wood, or crystal, based on the unit type. After recruiting, you can assign each unit on the front or back row of the battlefield. The units have different capabilities based on the row they are positioned at. When and where to summon each unit is of great importance as it can help you win the battle or change the tide. Every time you win a battle you earn experience point and gems which you can spend on buying new units for your army.
