I think this puzzle is ideal as an intro to the series. Very approachable, yet not flat.

Took me a while as a beginner, but the early coloring and the end solving were really smooth, I enjoyed that a lot, thank you !

I had a x wing on low what I called red and 5 in box 7 and 9. I assumed the 5 had to be on the white dot to disambiguate the puzzle. was there another way to do it?

Fun time with colors!

A wonderful puzzle! 15:18 for me. It was a smooth ride using the xvs to help color in the rest of the grid, disambiguating the numbers at the end

A bit easier than some of the other ones, but I liked the addition of 5 being allowed on the lines. 10:50 for this one today.

I rated this 2/5 difficulty.

Another great addition to the series!

This one felt quite a bit more approachable than most of the others (in this and similar series), but was just a bit too complex for a 1* rating IMO. I think it is on the easier side of 2*, and should be reasonably straightforward for novice solvers who are familiar with full XV ruleset puzzles.

I could also understand why someone may land on 1* difficulty (the current posted difficulty is still 2* though), but IMO this puzzle does require some XV tricks that a true beginner to the rules may not be familiar with.

The break-in for this one was easier than I expected, as my coloring seemed to expand outward consistently after starting (the initial colored cells I chose were easy to work with). The midgame was very smooth as well, and I made progress consistently. The final disambiguation was similarly straightforward.

Overall, very nice puzzle. Thanks for sharing!
