I went to my friends houde and played on this little machine. I had played the larger version of this and iwas very impressed. I ll tell you how it works for those who dont know.
Step 1: Think of something, it could be anything, fish tank, indian elephant, diamond,etc.
Step 2: 20Q asks you a series of questions like: Is it a oommon household object or does it have a wight colour.
Step 3: You answer each question by cliking one of 4 buttons, their is: Yes, no, sometimes and unknown. Their is also an undo button which takes you back to the previous question.
Step 4: Answer all the questions and 20q will quess, if it gets it right then you can play another game, if not then it continous guessing until 30 questions then if it still doesnt find it then it gives up.
I have to warn you this machine is pritty smart. I can guess: Duck billed platipus and alien and if your thinking of nothing then it can guess that to and also amazingly it guessed its self !. But it cant guess everything. I got really annoyed so i thought of carbon fiber which it didnt guess. Apart from that its a brilliant little machine and well worth 8 quid. Im getting this for my mates for christams!!!!
