Compared with the version "tangram my first" test and with young children.

The content is almost identical to the version "tangram my first."
The parts are tough as they are soft foam for "my first tangram". They form a 15cmx15cm square.
Foam, it is more difficult to handle because the parts do not slide on the table or on the introductory sheet.
With 4 game pieces, you can play 4, it's more fun when solitary.
The booklets are almost identical: They have the same figures. One of the booklets in a paragraph or two more for the rules of variants.

For young children, there are initiations full size sheets.
For "my first tangram" there has 6 figures with solution on the front (just put the parts where they are drawn); 6 and other figures on the back where there is just the outline (put 7 parts inside).
I tested these cards with children of 4, 5 and 7 years. Figures are with just the outline of a correct level of difficulty for their age. We just stay two side to advise them when they block.
For version "Black Series", the 12 figures (initiations sheets) are with solutions! It's too simple.
There are not enough of these forms of initiations with just the outline of the figures. I've made other (with a word processor). I will put them on a sharing site later when I finish reproduce those I have another book.

Playing with figures on the cards, it is better to have at least 10 years or some experience with the figures with the contour in actual size.
Only 64 of the 32 figures card. It's little. There are others in the booklet.
It would be better if the cards had the solution on the back.

I did not put full marks because there is little cards and few initiations sheets that have more complete solutions.
You can buy books that are several hundred figures or search online.
