Nice, simple looking physics game. Slide the different coloured balls into the corresponding targets, curling style, to complete each level. Good learning curve and a grid to help you hone your accuracy. With a limited number of balls, you'll soon be using pool table tactics to knock your balls into their targets. Good fun.
