Comfortably uncomfortable for me :). I really like how I literally have to think out of the box.

Rellik cages are mindboggling. I liked this puzzle a lot. Thanks.

You are much welcome, Klausku, thank you for your comment! I am glad that you enjoyed this puzzle. Concerning "mindboggling": Although I have thought quite a bit about the possible perspectives on Rellik Cages, I still feel there is a lot I have to get my head around. Hopefully, I can use the ruleset for some more interesting puzzles.

What an amusing puzzle! I laughed as the rellik restriction ping-ponged between the cages.

Thank you for your comment, OGRussHood! I am glad that you had a fun solve. The pingpong effect is something I really like as well about this variant/setup.

Really nice puzzle and a fun new ruleset, thank you! I would agree with 2/5 stars.
**
Thank you for commenting, MatthewDonovan! Nice to hear that you like this ruleset. I also agree that 2/5 is a fair difficulty rating. In the beginning, I had estimated it a little too lightly.

Amazing once again!! Super fun... This rule set needs to be featured on CTC.
If anyone is struggling with the ruleset then give the first puzzle a try, its a great intro puzzle. I definitely felt like this was smoother because of the logic I learned in the first. Great puzzle!!

Thank you for your kind comment, theParad0x! I am glad that you enjoy the variant and deem it CTC-worthy.

changed estimated difficulty from 1/5 to 2/5 due to first solvers responses, no changes to the contents of the puzzle

Very nice. Thanks!
Given my solving time it was a 2 star for me. And it was not so much the Rellik constraint that took the time, but the irregular. :-)
**
You are much welcome, Sinuit, thank you for your nice comment! I think you are right: The geometry/irregular sudoku is of more importance in this puzzle. I think I will change the estimated difficulty to 2/5 and we will see where it lands once the dust has settled.

This puzzle is fantastic. There are some new and fresh bits of logic that are very rewarding to spot. It's an intriguing new constraint with lots of possibilities. Well done!

Another excellent puzzle! I'm glad to see this variant explored further, thank you!
This might be more like 2 star difficulty, but I'm not sure.
**
Thank you for your kind comment, Puzzle Weasel! I am glad that you like this variant. Also thanks for sharing your opinion on the difficulty. I was a little torn between 1/5 and 2/5, so maybe it is a classic 1.5/5 difficulty puzzle. :)
Kind regards, sujoyku
