Logic Masters Deutschland e.V.

Lately Andrewsarchus has been making some too:
Active Loop
Active Friends
Active Circuits

The Rules:

1. [Sudoku] Normal sudoku rules apply, fill every row, column and 3x3 box with the digits from 1 to 9 once each.
2. [Renban] The blue lines are Renban lines, and must contain a consecutive set of digits without repeats.
3. [Active Cells] A cell is "Active" if it could be the destination of a numbered room clue--that is, if it is xth cell in from the edge of the grid, where x is the digit in the cell on the edge.
   Examples:
   • If R4C1 is 8, then R4C8 is active
   • If R1C1 is 7, then R7C1 and R1C7 are active
   • If R3C6 is active, then at least one of the following is true: either R3C1 is 6, R3C9 is 4, R1C6 is 3, or R9C6 is 7,
   Along every blue line, cells alternate between being active or inactive.
