The players filed into the empty prison, eyeing each other warily as they were fitted with explosive collars. Chishiya watched them from the shadows, smiling to himself as uncertainty mingled with desperation on their faces.

Once collared, you all made your way upstairs to the central guardroom where they would play the jack of hearts game. With a year's worth of food provided, survival seemed possible if they could only avoid the deadly consequences of a wrong guess.

You all listened quietly as the rules were explained. Each round, the symbol on the back of their collars would change and they must deduce its suit - hearts, diamonds, clubs or spades. They were free to conspire and form strategies - or to team up with others, but in the final five minutes could only disclose their guesses alone in solitary cells. To view the symbol through reflection or to attack another player meant instant death.

As the round timer started, Chishiya blended in, observing the factions that quickly formed. Some were panicked, others arrogant in their assumptions.
