the aim of the game is to bounce your ball off the pegs to hit all the orange pegs but you only get ten balls which fall out at the bottom of the level. the blue pegs are there just for the level and you can score from them. the orange pegs are the ones you need to clear, green give you power-ups and the purple ones give you high scores. If you manage to land the ball in the hole at the bottom then you get an extra ball and the same if you score 25000 with a single ball. There are also other bonuses for things such as sliding the ball or bouncing it into the hole off the wall.
The game starts off with 10 so called masters each with their own power-up. Each master has 5 levels each with their own difficulty and tactics. The great thing about the game is that there is an element in skill in aiming the ball but once you press fire the game becomes more of luck and chance and hits will happen without you predicting them. Overall the game is very addictive and is well worth it for 59p however I am not sure what the original price is but it is still worth it.
