TETCOLOR

This game was written in Pascal by an employee of one of the Tula research institutes in 1991. Despite the external similarity with Tetris, it is not a perfect clone. The major differences are in the very principle of cleaning the screen. In Tetris, for this it was necessary to build continuous horizontal lines, but here lines of at least three cubes of the same color can line up horizontally, vertically and diagonals to be cleared.
