Hydras is a quick and easy card game with elements of tile laying games and some "take that" mechanics. The game is for 2-4 players, takes about 5 minutes to teach, and around 15-30 minutes to play. Each player starts with a hydra body card and takes turns playing and drawing cards. Cards can be played on their own hydras to build up their defenses, thwart or undo their opponent's attacks, and increase the number of heads on their hydra. They can also be played to attack your opponent's hydras by cutting off heads or burning stumps. The game ends when the deck runs out. The player with the most heads at the end of the game wins!
