Samurai Star
You might be pleased to know that today’s puzzle is somewhat easier, despite being a lot bigger! It’s actually possible to comfortably solve this without making a single pencilmark, if you fancy an extra challenge.
It’s a Samurai Star / Flower Samurai puzzle. Just place 1 to 9 into each row, column and 3×3 box of the 5 underlying grids (there’s one in the centre too).
Good luck!

That was fun. I am enjoying the samurai flower pattern.
One rule I have found with this pattern is that for the long rows/columns, Any triplet set of digits within a box must match the box that is 3 distant (in any order).
I guess you could call this the Samurai Flower Rule if you wanted to. Thinking along these lines, you can apply this to other overlapping samurai patterns (with heavy modification of course). I was using this a great deal for the earlier skyscraper samurai puzzles.

A great puzzle made more enjoyable by the fact that I took you up on your challenge and managed to complete it without pencil marks!

The no pencil mark challenge was great. I managed to solve this one without them as well, though in a little more time.

One thing I’ve been meaning to work out is whether it’s actually necessary to state that there is a centre grid, or whether it just falls out of having 4 grids around the outside already. If so, it will simplify the puzzle description and leave something more for the solver to discover as they go.
I could easily see if this is likely to be true by building lots of test puzzles, but I think a more reasoned approach would be better.
