okay, you need to enjoy puzzles, have intelligence, and possess patience in order to play the game. One of the reviews above completely exaggerates the load time between screens and puzzles.
My friend and I played this game one Friday night because we enjoy brain puzzles. Although several people who came over claimed what we were doing was boring, pretty soon a house full of people were all trying to solve the puzzles. You need to REALLY think about some of the puzzles, you can't solve them in thirty seconds. It took 45 minutes for us to work out some of them. the ONLY place we really got stuck was the snooker puzzle where there actually seems to be an error.
We used up countless pieces of paper writing out patterns, figuring out various puzzles. If you enjoy games where you actually have to THINK, then you will enjoy this. I also suggest a group as it is waaay more fun that way during the lulls where you are working to solve the puzzles on paper.
It's really sad that this game was too difficult and couldn't hold the interest of most people. I am definitely not the smartest person in the world, nor am I very patient, but these other reviews certainly made me feel much more so.
yes: I recommend this product
