You can play with the automatic machine (with difficulty levels beginner, intermediate, or expert), or with a friend using the same phone or using another android phone/tablet as a network game through WIFI or Bluetooth.
For those who don''t know carrom game, it is a strike and pocket game similar to billiards, pools, snooker and shuffleboard; Here in carrom (also known as karrom or carom) you will use the finger to shoot the pieces. (Reference: Wikipedia).
Controls are intuitive to any gamer. You will aim and shoot similar way you shoot in angry bird games. The game includes both a quick and a comprehensive tutorial to make you familiar with all the controls.
The game simulates the physics of the carrom accurately. You can try out any zig-zag shots you used to play in a carrom board.
At the start, you can play with a beginner machine, until you get familiar with the controls. Then try out the intermediate machine which is bit competitive (for me, may be not for you). The expert machine is there just to watch. Look at the video below for a classic carrom game between two expert machines.
Enjoy and have a great carrom season!!!
