but you can change another block - you can select blocks without star too, so you can select them and they can change colors, you can get the color you need but this way...
I get 3 white and 1 black, then rearrange the colors and get only 3 white. - that is good, you only change the right position of all balls, so black ball disappear.
I've also gotten 3 white and 2 black, which is an impossible combination - why??? this is possible..
