hi!
Ok, here comes the solution:
1) select the left white stone and shift it to the left. It will fall down. Leave it there.
2) Take the second white stone, shift it to the left, it will fall down, shift to the left again and again, until it reaches the other white stone.
3) Select the left green stone and shift it to the right. It will fall down. Now shift it to the left one time. Leave it at that place.
4) go for the left blue stone, shift it to the right, let it fall, shift to the right again and leave it.
5) Now the other blue stone. Shift it to the left, after it fell down, to the left again. It will touch the other blue one.
6) Shift the lowest of the three violet stones to the right and after it's fall on time to the right again. Leave it at that place.
7) Shift the lowest of the three orange stones to the right and after it's fall to the left until it falls again. And now to the right. It will fall again. At that point, shift it TWO times to the left and leave it at that place.
8 ) Take one of the other orange stones. Bring it down to the level of the first one, but they should not touch eachother. This two orange stones should be brought to a position that allows you to let the third orange stone fall into a gap between the other two stones.
9) Select the upper left violet stone and bring it down where the orange stones have been before.
10) Locate the upper green stone near to the other green one.
11) Do the same es for the orange stones for the violet ones.
Well, that's it
