Carrom Superstar has various game modes: you can play matches in local mode against the AI. During each turn, you have to move a counter and throw it against the black or white pieces, depending on which one is yours. The idea is to get the corresponding colored counter to fall into one of the four board corner pockets. There are always two scoreboards at the top of the screen.
As for the controls, players just have to adjust the position of the counter they are going to throw. To do this, you have to slide your finger on the bar at the bottom of the screen, which will let you move the piece horizontally. Then, by tapping the piece and dragging it backward, you can control the angle and power of the shot.
Carrom Superstar is an entertaining game that has adapted this popular board game well for touchscreen devices.
