When you are solving the puzzle, you should follow two rules: 1. You must use all the pieces. 2. The pieces must not overlay each other. First levels are really easy. It will help you to learn how operate pieces and understand common rules.
The idea to create such a game came while walking around the city. I came across the sellers of these Tangram puzzles, there were a crowd of people near their tables who were just trying to solve them and very few succeeded. I tried it myself and really liked it). I advise you to try it too, starting from level 3 the fun begins.
I hope for your feedback in the comments, this will greatly help in the further development of the project. Thank you!
