Tangram is an ancient puzzle that was invented around the 18th century and is one of the most famous in the world!

"Tangram" consists of seven boards, which, according to the condition, must be combined into the desired figure. From these elements you can make... practically anything! These can be animals, vehicles, numbers and letters, various objects, etc. In addition, the elements of the puzzle provide a huge space for creativity - build figures that are not in the puzzle book and realize your own ideas. The game helps to develop logical thinking, imagination, attention and combinatorial abilities.

Task: make 525 figures, using all 7 Tangram pieces for each of them (the book with tasks is included).
