The anime is an adaptation of the games, faithful, but it still differs at some points.

Example, the Raimon vs Chaos match was relevant plot-wise to the anime, while in the game, it's merely optional. In the anime, Endou learns Majin The Hand during the match against Zeus, while in the game, he learns before it.

And there's the manga, which differs greatly from both the games and the anime.

To sum it up:

Games: Canon / Main source.

Anime: Adaptation, includes content, matches, etc not present in the game canon.

Manga: Same as the anime, except not as loyal. For instance, it ignores the Aliea Arc.
