as easy as 12 ... 4

What does that mean? You think the difficulty is 3 stars?

Thank you for a lovely puzzle. I think 3 stars is fair as it is not at all obvious where to look for the break in. It took me absolutely ages to get going, but once started it all solved very smoothly.

You are much welcome, Hamsterbase, thank you for your comment! I absolutely agree that the break-in is harder than what follows. Thanks for sharing your perspective on the difficulty.

Thank you for all your kind comments! I am glad that you liked the puzzle and mostly found it approachable enough to be 2*.

as a beginner who definetly cant solve 3* yet, this is a very enjoyable 2* puzzle!

Very nice puzzle! I liked the break-in. I would say a 2.5 stars, but I’m not an expert solver. Anyway, thanks a lot!

Nothing crazy about this beautiful puzzle. 2* for me.

Not even a little? Do I have to change the title? :)
But without kidding, thank you for your comment, GeorgeTheToad2!

Fun puzzle, I guess easier than 3 stars. Thanks!

You are much welcome, Snookerfan, thank you for your comment! I am glad that you liked the puzzle. Difficulty was hard for me to estimate because of its decrease after the break-in. Let us see where it lands. I certainly won't be disappointed if the majority of people has it at 2*.

Very cool break-in, not where I expected it at first glance. 11:35, so 2 stars for me. Good fun, thank you!
