There's no getting away from it, this is a computer version of the board game Cluedo. The butler has been murdered, his body dumped, and it's your job to deduce the criminal from the assembled guests, together with the weapon and the location of the dirty deed! Though you can play on your own, it's better with friends.
Each of you assumes the role of one characters, and the dice is thrown for each player. This determines the maximum number of moves you can make in one turn. The character you choose is shown as a little head, finely drawn, and the playing area is the plan of the house. As you move into each room, you may make an accusation as to murderer and weapon for that room. The computer responds, showing you which, if any is correct. You thus move about the house and garden gaining clues as to who didn't do it, 'and what they didn't do it with! From this, you work out who did, and with what.
Graphically this is good, with nicely chosen colours and neat movement. If you like Cluedo, or indeed, not too complex games of deduction, you'll enjoy this. I have to admit to being biased, I find the original very boring, though this is better.
Instructions both written and on screen are adequate, but loading is in slow mode only. Quite reasonable as a game, but in my view not worth this sort of price. £5.95 would be more realistic, and that's pushing it!
