An easy 6x6 with skipped numbers.

Following the honkhonk's idea of skipping numbers (thread "if you have time left" in this Section "Specific puzzles / your own puzzles") I have developped an easy to solve experiment, in the 6x6 format (with a unique solution); see, for instance, how simple is to almost inmediately determine d4, also using the parity rule, as in the standard puzzles.

Even without the parity rule, d4 is trivial to determine because you
give all 6 numbers, no?

Wouldn't it be more interesting if not all 6 numbers were known from the start?

Yes, Patrick, you are right, giving all the six numbes was intentional, in fact I was initially thinking of not including the comment below the puzzle so forcing to deduce the components, very easy, the six numbers, this particular puzzle is made to recall the attention of beginners, that's why that reference to the "parity", which in some way drives them to the "addition rule" (30, even, in this case and not 21, odd, etc.), obviously the "9" can not go inside the cage "45x" if the "1" does not exist, the puzzle itself is really easy, once the initial "surprise" has passed, it can be made with the components hidden, but that's the general idea about the possibility of creating puzzles of this type and even they could be made with some negative numbers to be deduced along the solution process... In other cases, the information of the numbers that compose the calcudoku may be given as a line below, as we do in the actual "fm 0" puzzles, when in some way it is "obvious" since the "0" always appears, alone or in cages "0x" or ":".
It's just an amusement for a "saturday night and sunday morning" (was that the tittle of that Karel Reisz's film?).
