I have the white set and now the new black set. Both versions have a starter set (written on the package and usually the most expensive) and extension sets (cheaper and written on the package, but very small). There are also special additional parts, such as a trampoline, etc. These cost between 10 and 13 francs. These are between 10 and 13 francs. The colour of the package shows whether it goes with the white or black version. I don't know if these go with both. Probably not. For the black version, there seem to be only two additional parts at the moment. For your information, our son is getting the black version for Christmas. So it hasn't been unpacked and tested yet.
