Boom roller app for iPhone and iPad
As the coloured balls popus down from the tubes you need to be quick and switch the cones below to match the colours, if you miss then you are out!
Simple (ish) to play for all ages by tapping the screen,
you need to be 100% focused in order to get all coloured balls to match the drop down cones.
No ads, no in app purchases, just 100% pure arcade fun anytime!
