Sorry, I have a question.
Is 'Planets puzzle' similarly of 'Puzzle Q' ?

(Sorry, this site was written by Japanese. Please check only photos.)
It looks similar puzzle, does Planets puzzle's each sphere have 6 hollows ?
If these two is same, I can solve it.
But there are three problems.
1)I can solve it when I solve it, but I didn't fix the solution. Some steps are trial and error.
2)The shape is difficult to draw for solution.
3)I can't use English well.
If you don't worry about my poor English and figures, and you can wait for a few days or a week, I'll try to make the solution, and upload to my site.
