You have been randomly and anonymously paired with another participant. Both of you must choose either Deny or Confess. This gives four possible outcomes, each with a different payoff, as shown in the table:

In each cell, the amount to the left is the payoff for you and to the right for the other participant.

		Participant B
		Deny	Confess
Participant A	Deny	{{ Constants.both_deny_payoff }}, {{ Constants.both_deny_payoff }}	{{ Constants.betrayed_payoff }}, {{ Constants.betray_payoff }}
	Confess	{{ Constants.betray_payoff }}, {{ Constants.betrayed_payoff }}	{{ Constants.both_confess_payoff }}, {{ Constants.both_confess_payoff }}

• If both of you choose different strategies, the one with co-operation will get {{Constants.betrayed_payoff}} and the other will get {{Constants.betray_payoff}}.
• If you both Confess, both of you will get {{Constants.both_confess_payoff}}.
• If you both Deny, you both gain a reasonable amount ({{Constants.both_deny_payoff}}).

Participant A is the first mover and can decide to Deny or confess against participant B. After that, participant B (the second mover) will be shown the decision of participant A and participant B have to decide whether he/she should Confess or Deny.

The scores from each round are accumulated, so the object is to optimize the point score before reaching game over.
