How to Play CastleArena.io
Click and drag cards to your side of the arena or use the hotkeys 1-8.
Choose your upgrades by clicking the arrow.
Try to time your attacks so your opponent will have a hard time defending it. You can set the spawn point of your units by clicking into a building and then in a adjacent space, use this to your advantage!
Buildings are always more cost-efficient than units, but they are slower and have less instant impact.
Use unit cards to gain momentum or in anemergency defense.
Notice that unit cards don't generate wood or income. Keep that in mind so you don't ruin your economy!
