Card Barrage

From BoardGameGeek:

Card Barrage is a head-to-head dexterity-based tower defense game. Players hone their dexterity skills and finesse at card tossing through attacking your opponent's castle. At the start of the game, players lay out a card to represent their castle and its surrounding wall cards. Each turn, players physically toss cards against the other player's castle and surrounding wall cards. Players score points when their barrage cards land on the other player's castle or wall cards. Wall cards can be damaged and destroyed through attacks. You can play solo, head-to-head or team vs team. Rules govern how you can toss cards to attack through the lob, Frisbee, or flip method. OBJECTIVE – The objective of Card barrage is to score points through attacking your opponents' castle and castle walls. Successfully tossed cards that land on your opponent's castle or is surrounding wall cards will score a point. GAME PLAY – Each turn players may build a wall, upgrade a wall, and attack. Build a wall by playing a card into a previously destroyed wall section. Upgrade a wall by exchanging a wall card with a card in hand. If you did not build a wall, attack an opponent's castle and wall by tossing a card to score points. GAME END AND WINNING – The game ends when one player has scored 10 points or destroyed all their opponent's walls and then hits their opponent's castle with all players getting an equal number of turns. The player with the most points wins. THEME – Medieval Setting and Castle sieges -description from the publisher
