Assassin is a casual multiplayer format where the players are randomly assigned “targets” to defeat.
Player are free to attack whomever they want. However, victory is not determined solely by who the last player is, but also who manages to take out the most marks over the course of the game. Players score points for delivering the finishing blow to their assigned target as well as being the last survivor. Defeating another player grants you their mark immediately upon their death, and thus a new target to attack.
Each player is assigned a number based on their seat. Then is given a card a random with a number different that their seat number. That card is their “target.” If they are given the seat number they are in then collect all the cards and distribute them randomly again.
Defeating a mark grants you 2 point.
Being the last one alive grants you 1 point
