joystick games

I've recently bought a PTron gamepad for my android mobile. But I can't feel that joystick may be the joystick or the games doesn't accept gamepad controls. Can anyone suggest the best gamepad games for android. I've played the car racing games only.

 

Try Rayman Adventures

 

Is it a free game or paid one.

 

Actually it's free, but as usual there are ads, there are different items in the shop... but it's really fun)
