I realised recently that I never made a Schrödinger cell puzzle, after solving James Sinclair's excellent Ungapatchka. So, I made this to fix the lacuna in my puzzle list. It's pretty tricky, so I'm thinking it's at least 4* - please enjoy.

The Rules:

• Normal Sudoku rules apply.
• Sudoku: place the digits 0-9 once each in every row, column and box.
• Schrödinger cells: each row column and box has exactly one Schrödinger cell, which contains exactly two digits. No two Schrödinger cells may share the same pair of digits.
• Cages: digits in a cage must sum to the total in the top left corner of the cage. If a Schrödinger cell appears in a cage, both of its digits must count towards the cage total. Digits *can* repeat in cages, if allowed by other rules.
• Renban: purple lines are renban lines. The digits on a renban line must be a consecutive set of digits, but may appear in any order. Digits may not repeat on a line. If a Schrödinger cell appears on a line, both of its digits count towards the consecutive set, and neither can repeat elsewhere on the line.
