How to Play
25 notorious criminals were paid to take part in a psychological experiment. They were all placed in individual rooms (arranged into the 5x5 grid seen below) and each one received a 'shock switch' that he/she could use to deliver an electrical shock to the other prisoners in his/ her row. Each prisoner had to choose whether to turn it ON or leave it OFF. Here's how it worked: if NONE of the prisoners in a row used the switch, then none of the prisoners in that row were shocked. If SOME (but not all) of the prisoners in a row used the switch, then a MODERATE shock was delivered to the prisoners who left their switches OFF. If ALL of the prisoners in a row used the switch, then a SEVERE shock was delivered to ALL of them. Use the clues to find out who turned their switches [ON], and who left their switches [OFF].
