	Given your description, this is NOT a "simple logic game"... There
is, in your description, NO LOGIC to apply. That is, there are NO clues
provided to the players.

	Consider:

7 candidate suspects
3 of the 7 are guilty (perpetrators)
3 of the 7 are listed to the players (these three may or may not be in
the list of guilty)
"computer also tells the player how many": OKAY, ONE CLUE... but if the
computer says "0", then there is nothing for a player to do. Similarly,
if the computer says "3", then all of the listed names are guilty --
again, nothing for a player to do.

Therefore, the only "play" occurs if the computer says 1 or 2 of the 3
names is in the guilty list.

With three names, and one candidate, the first two players are going on
sheer luck (if they guess wrong, the third player picks the third name
-- win). And with two candidates, you again have just three
possibilities: A & B, A & C, or B & C... So again the first two players
are just guessing, and if they don't guess right, the third player picks
the only remaining choice and wins.
