Es gelten die normalen Sudoku-Regeln: Setzen Sie die Ziffern 1 bis 9 in jede Zeile, jede Spalte und jeden 3x3-Block ein.
Anti-Springer: Zellen, die durch einen Springerzug (wie im Schach) verbunden sind, dürfen nicht dieselbe Ziffer enthalten.
Pfeile: Die Ziffern entlang eines Pfeils ergeben als Summe die Ziffer im Kreis des Pfeils. Ziffern dürfen sich auf einem Pfeil wiederholen, sofern die übrigen Regeln dies zulassen.
Vierlinge: Die Ziffern in einem großen weißen Kreis auf einem Zellenschnittpunkt müssen mindestens einmal in den vier umliegenden Zellen vorkommen.

I found this to be 1.5*. Didn't use Phistomefel. Quad interactions plus arrows got me some good progress. Knights move finished it off. The extra .5* is because you have to understand how quads in 2 boxes interact to restrict a 3rd box and some of the more subtle knight's move logic.

Lovely puzzle, but I agree with others that this is a 2 star puzzle. I did not use the Phistomefel ring, but some of the cleanup and deducing digits requires a 2 star number of steps, in my opinion.

Solid 2*, even with knowing the Phistomefel ring; FAR too many tricky deductions to make for it to be considered any less.

Nice one. I think you can rate it 2*, because the break-in is nice and it then requires some effort to clean it up. You don't have to know Phistomephel's ring at all, and if you know it, it's just minor help for the break-in.

Same here. I am familiar with Phistomel’s ring, but as others pointed out you don’t need it. The quadruples with the arrows and the antiknight to cleanup options make it a very doable 1* puzzle.

I agree with Mozart, you don't need to know about the ring to solve this puzzle, at most you would need to know about quadruples (and their implication), so I think 1* is fair

I solved it without Phistomefel and consider it still as 1* puzzle. But nevertheless a fun sudoku.

For a beginner a 2.5*. I agree with other posters. If you need to know Phistomefel ring it's not a 1*. Once past that it's doable, but takes a while to figure it all out. Took me about 50 minutes. ¯_(•_•)_/¯

Really enjoyed this, especially after I remembered the anti-knight rule. I'm of the opinion that 1* should not require knowledge of theory though. I may be holding a minority opinion on that.

Some specific knight logic in there. So perhaps if you are less familiar with how the knight rule restricts other squares, this will certainly be 2*. Otherwise 1*.

Very nice puzzle

Nice puzzle, but personally I'm not ready to rate a Phisto puzzle just 1*

Submitting as 1* but up for review
