Players must select their heroes and use their skills to defeat their opponents each turn, based on a set master of a given skill. It's also important to figure out which master they are and defeat them.
There are four faction cards in Valentine. Players of three to six are randomly assigned an affiliation card and must fulfill their role throughout the game.
Once you're aligned, you'll pick a hero to recruit each turn. You start by picking your own hero, and then pass the rest to the player next to you. This is psychologically strategic, as you have to make your picks while trying to anticipate what your opponent will pick.
Once all players have chosen their heroes, they are called out in turn, starting with number one, and the battle begins. You'll need to use the compatibility between your characters to make predictions and attack the enemy.
As each player progresses through the game as a Heroic character, they take hits to their HP and gain access to unique abilities through their affiliation.
