Professor Fizzwizzle has created a train! It doesn’t run on diesel fuel or
coal, though. You provide the fuel. The fuel is brain power.

There are fifteen mini-games from five categories. The categories are:

* Memory: You must remember an item or pattern.
* Search: Find the answer on the screen.
* Planning: Decide on your path.
* Spacial: You must solve questions based on a three-dimensional image.
* Numbers: Solve equation-based questions.

There are three modes on play. In Test , you are given a mini-game from one
of the five categories. Solve as many puzzles of that game in one minute. Then
it is on to the next category until you go through all five. In Quest , you
accept quests from the animals along you track. When you want to travel to
them or do their quest, you will play a mini-game to fuel up the train. Each
mini-game will be limited to one minute. As you complete quests, you can open
more track and, hence, more quests. In Practice , you can select any of the
fifteen mini-games to practice on, with or without a time limit.
