Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Killer: digits inside a caged region must not repeat and sum to the total shown in the corner.
Quadruples: each digit shown by a quadruple clue appears at least once in its four surrounding cells.
Even/odd: cells marked with squares contain even digits, and cells marked with circles contain odd digits.
Cells connected by an X sum to 10. Not all Xs are given.
Digits may not repeat along marked diagonals.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of row 2.

To the setter: you need to work on your setting (in the terms of format) skills. I had to guess a few things for the cage as in the set grid itself, nothing shows up, and it's partially hidden in the picture on this page. Once I knew what the value was, the puzzle actually we pretty smooth, but... yeah, couldn't give it a good rating because of that.

I agree with the last comment. These puzzles always feel inhuman, with computer-like deductions needed.

No human being would ever set a puzzle that obscures clues like this.

One of the more easier ones IF you realize the cage total is hidden on SudokuPad but partially visible in the image here.

Accidentally put in odd digits in the square at first, which made the puzzle far more challenging and engaging, until I realised that there were multiple solutions and re-checked the rules.

Die Summe in der Killerbox ist 3. Kann man in SudokuPad nicht sehen.
