I agree with the other comments that this game looks childish, but in my opinion that's where it stops. Some of the memory tests get very difficult, well they did for me. If you haven't done even simple mental arithmetic in a long while, you will find this a challenge. Dexterity with the use of the arrow keys can also prove a challenge. OK, I'm 67 so my reactions will not be those of an 18yr old. BUT with practise using this game, they will come back!!

This has lots of different mental challenge puzzles. The puzzles get harder as you conquer them in the time permitted. For ages 8 and up.

There are many different puzzles challenging you on memory, spatial acumen, quick thinking, problem solving, etc. It's a fun version of the popular "brain training" type games.... All games start out very easy but quickly become quite challenging... You can play in either timed or untimed mode. There are three forms of game play: quest mode, test mode, and practice mode. In quest mode, you have to fuel up the train by completing various puzzles which are given randomly. The other two modes are pretty self explanatory. Don't be fooled by the somewhat childish graphics and quest text - which, to me, make the game seem to be aimed at kids. This, like all the Prof. Fizziwizzle games, is great fun and challenging for all....
