Release of ZweiStein, a TUI implementation of the Einstein puzzle

project ZweiStein prepared a remake of the Einstein puzzle (Flowix Games), which in turn is a remake of the Sherlock puzzle written for DOS.
The program has a text user interface (TUI) and uses Unicode characters. The game is written in C++ and spreads licensed under GPLv3. Prepared for Linux compiled version (AMD64).

Remake goals:

• Get rid of the menus and things that in the puzzle game do not carry a payload (save, high score table) and only move the player away from the actual game.
• The Flowix version is written with a 4:3 screen aspect ratio and does not look very good on monitors with other characteristics. Also, the game is difficult on modern high-resolution monitors in non-full screen mode.
• In the future, it is planned to add the ability to flexibly adjust the level of complexity, indicating the ratio of different types of "hints".

Rules of the game:
There is a 6x6 field filled with different characters in such a way that each line can contain characters of the same “class”. For example, in the first line there are only Arabic numerals, in the second - Latin letters, etc. The player's task is to determine which cell of the field contains which letter. For this, there are hints that describe the relative position of various letters. For example ¥⇕Θ means that the signs ¥ and Θ are in the same column. There are 4 different types of hints in total. More details can be found in the in-game description of the rules.
