Simple but effective
As this is not an original game but based on a game that has already been invented, I think that one can only review the Flash adaption of it.
I loved the the 'note-pad' theme of the game; it gives it a lovely atmoshpere, because that's how you would actually play it in real life! This was it's outstanding feature in my opinion. I liked the full explanation of the rules and scoring, very clear and easy to follow. I thought the interface was nice and clean too. I've played for a few hours now and as far as I can tell it's bug free. I liked the awards, but would have been nice to have them as NG medals too.
Criticisms: I found it too easy to beat the computer, even the "Realistic" one. An extra level of difficulty would give it a bit more longevity. That damn advert that popped up every so often when I just wanted to get on with another game, but it's difficult to criticise because it has to be funded somehow. It was a small price to pay on reflection.
Overall, I thought it was nicely done. Sometime less is more!
