Originally released in 1996 as the Amazing Learning Games with Rayman, Ubi Soft rereleased the game in 1999 as three volumes of the Rayman Learning Center. In the 1996 version players could choose from three difficulty settings. In the 1999 release the difficulty setting was already chosen, hence the "ages 6-7, 7-8 or 8-9".  

"Knowledge is power - especially for a superhero. That is exactly what children will discover as they take on the role of Rayman in Ubi Soft's new 3 volume edutainment PC series, Rayman Learning Center. Children read, count and spell their way through 6 amazing worlds to rescue the "Magic Book of Knowledge" from the evil Mr. Dark with Rayman. The adventures are so exciting, the challenges so involving, and the action is so intense, that children will forget how much they're learning." (from box)
