“logic rather than mathematical computations”: Sorry, but this is not true. “a > b” is one of the simplest mathematical ideas going, but it is most certainly mathematical in a way that standard Sudoku is not. In a Sudoku puzzle, you can replace the numbers 1-9 with any nine different symbols - nine types of fruit for example. In a futoshiki puzzle, you CANNOT do this because the solver cannot decide whether {apple} is more or less than {banana}.
