Whodunnit -- Think Quickly is a crime fiction puzzle game where you play a veteran detective faced with the urgent task of finding the perpetrator who poisoned the teapot, from which all dinner guests for the evening had just drank from.
Your objective is to prove all but one of the guests innocent of any wrongdoings, which can achieved by finding either an alibi, lack of motivation or incapability to handle poison. When making your accusation, you'll be asked to explain why each and every one of the other guests are to be presumed innocent.
The stress level will rise slowly during the course of your investigation, but you can stay focused on the matter at hand by relaxing or lighting up a cigarette. Use the F1 function key to view some hints for the game. You will also need a pen and paper to take notes.
Whodunnit... Think Quickly does have a few glaring flaws. Solving cases at the highest difficulty level requires the player to ask too many questions within the time limit, while simpler investigations can be solved just by thinking about all suspects in the room.
