Castle Panic is a board game designed by Justin De Witt and published by Fireside Games in 2009^[1][2][3] Castle Panic is a tower defense strategy game in which players work cooperatively to protect a castle from monsters. The game was a nominee for the 2010 Golden Geek Best Family Board Game.

The game is set up in a circle. The circle is divided into 6 arcs of 4 rings each. Each arc is assigned one of three colors; blue, red or green. Each ring of the circle is subdivided and labeled either forest, the outermost ring, moving inward with, archer, knight, and swordsman rings respectively.^[4][5] The objective of the game is to kill the monsters invading from the forest before they can destroy your castle. Each player has their turn in order trading, attacking, and potentially repairing their castle. After the players turns, monsters are added and move toward the castle. If they have already reached the edge of the walls or towers of the castles they will attack the obstacle in front of them. If all the towers are destroyed the monsters win and the players lose. Monsters are defeated by using cards from the current players hand to attack them. Each card attacks in its colored area and class location, e.g. a blue archer can only attack in the blue archer space. The exception to this rule is the hero who can attack in any ring of their color.

Each turn consists of 6 six steps

1. Draw cards up to the hand limit.
2. Discard and then draw a new card (optional). This is useful to remove cards that aren't helpful to the player.
3. Trade cards with other players (optional). This allows you to get the cards you need to survive while giving players cards they will also want or need.
4. Play as many cards as you want. This of course is used to defeat monsters and protect your castle.
5. Move monsters into the next closest ring.
6. Draw two new monster tokens and add them to the board. Their position is determined by a roll of the dice.
