Chaos Construction Containing Circles Counting Correct Cave Clues
(Published today, 00:00 by Scojo)
Rules:
- 0-4 Chaos Construction Sudoku: Divide the grid into 5 five-cell orthogonally connected regions. Place the digits 0-4 once each in every row, column, and region.
- Consider every cell of the grid to be a cave clue (which may be correct or incorrect). A digit in a correct cave clue counts the number of cells in its region seen orthogonally from that cell (including itself), where region borders and the edge of the grid block vision. A digit in a circle counts the number of correct cave clues that exist in its region.

Love the ruleset! Once I actually trusted the puzzle enough to solve it, rather than wasting time investigating all possible cave clues in all twelve 5-cell regions, it was smooth sailing, well signposted and resolved beautifully!
