Watch a video. Occasional letters and symbols flash onscreen. You must 'guess' the killer by remembering the letters - only those used in the killer's name will flash up.
Tests quick recognition of lettershapes. This is something that no other game - to my knowledge - does.
No evidence of thought given to escalation in difficulty, variation in activity or anything else that might make this game fun for longer than the first game.
The trial is somewhat insidious - allowing you to 'play' the game (watching various videos) until you choose to guess the killer. Only purchasing the game will let you know if your guess is correct or not. This seemed - to me - such an egregious practise (preying upon your compulsions rather than trying to offer something of value) that I'm deterred from purchasing any of the company's other games - including one that I expected I would soon purchase.
Lesson: Though some may be suckered by psychological ploys, some will be turned off. Of course, Farmville suggests that the power of compulsion makes the first group stronger. This, if course, in turn raises various questions regarding one's own ethics and morals.
