The action takes place in some mysterious Brain Institute, where an eccentric professor-guide (voiced by the famous American comedian Fred Willard) takes the player through five different laboratories - Logic, Mathematics, Language, Concentration and Memory.
In each laboratory, the player is invited to take 3 different tests, the essence of which is to correctly answer as many questions as possible in a limited amount of time. The tests are varied and in each case correspond to the direction of the laboratory - from putting together puzzles and memorizing a picture of a crime scene to choosing the right rhymes for words, driving a car and unraveling tangles of intertwined ropes.
The temperature of the brain depends on the speed and correctness of the answers: the better the results, the stronger the brain warms up.
