RULES : Classic Sudoku rules apply. Additionally,
- Thermo Sudoku rules apply, i.e. there are some thermometer shapes in the grid. The digits are in increasing order from the bulb to the flat end of each thermometer.
- Renban Sudoku rules apply, i.e. each purple line contains consecutive digits.
- X Sums Sudoku rules apply, i.e. the clues outside the grid indicate the sum of the first X digits placed in the corresponding direction, where X is equal to the first digit placed in that direction.
I solved this on in 20 minutes, including a restart after 10 minutes because of a mistake. The interactions between the constraints are spectacular.
ReplyDeleteGood timing. Thanks for the feedback.
