Super Gem Shatter has over 150 unique powers broken down into 12 elemental themes. As you drop your gems you build up meter which is used to select both passive and active powers. You're free to go all in on one element (water, fire, psychic, etc), or mix and match different elements to create brand new builds.
Super Gem Shatter has an arcade mode where you fight through all 12 elements. There is also an infinite boss rush mode where you can test your skills against more and more difficult versions of each element. You can also play local or online multiplayer against a friend.
