Thanks, I'm glad you guys liked my bitwise OR puzzle. Hopefully I'll eventually be able to make puzzles that are *kinda* harder AND have a single solution.....

Yes, thanks skeeter84. It’s been a while since I’ve had a chance to do a bitwise OR puzzle.

Congrats Patrick.
You have created a fun site.

TY fzpowerman.

as a nudge to Patrick, if you do expand the database, people can finally submit the 21 x 21 puzzle. [wink]

Skeeter's puzzle was an enjoyable experience......I was able to do it on screen without having to print it off and look at possible solutions for various cages......enough of a challenge to keep me entertained for a while......look forward to more of the same......thank you [thumbsup]

Thanks, skeeter84, fot the puzzle [thumbsup]. Not difficult, but I have enjoyed it a lot. For this type of puzzle it is not necessary to create a twin, IMHO. A single puzzle is OK. To verify the unicity, the procedure I follow is to solve it analitically: if there is more than one solution you find them quickly.

The first of this type I sent, Feb 19, 2014, ( https://www.calcudoku.org/user/2014-02-19 ) was only a 7x7, yours is an 8x8 and I hope someone sends soon a 9x9 :-) .

With respect to the 25x25, thanks in advance to fzpowerman47 [thumbsup] , tremendous effort!!!. I have not tried it yet, but at a first glance it does not look very difficult since all cages are of one or two cells, and the puzzle is divided in five groups of five lines, either horizontally or vertically.

The main problems with very very large puzzles, apart of time consuming, are:

First, to provide space in the screen for the puzzle itself (I suppose that, in a mobile, it will be crazy), and to provide space in the window to send the solution, wide enough for around 40 digits.
Second. If you print it on paper you need a DIN A-3 sheet, at least, since, in a DIN A-4, the numbers are very small and it is difficult to follow the rows or columms and also you have little space in case of writing candidates in the cells.

In fact, I am thinking, when the puzzle officially appears, to go outside to obtain a printed copy in a big size paper (I have not an appropriate printer for it). In the other hand, to do it manually looks tedious :-) :-)

Also edited the top post, and posting here to make sure more people see it:

you can now get 25 points [woot] for the correct solution, use the puzzle code:

Great! That’s a opportunity to make up for the 7 points I missed out on yesterday. Might take quite a while to solve, though.

Yesssss, awesome, thanks and thanks again, Patrick [thumbsup] [thumbsup]
As Skeeter84, congrats to you and your site that I like very very much.
That said, you'll see, the 25x25 puzzle I made is enough easy.
I hope you'll like it. [smile]
