There are 39 unlockable skins in this game. You have to play through
almost all modes and master most of the game before being able to get
the last ones. In the US version of the game you get random set of
skins through certain level ranges instead of set levels as described
here. But the sets are not completely randomized and the later skins
are still obtained in the end.
