Excalibur, Super-Indexed
- XV and number dots
- Thermometers
The brief
Normal Sudoku rules apply. Numbers on thermometers increase from the bulb end. Numbers with an X between them sum to 10. Not all possible X are given. ALL numbers on the grid are super-indexed with two other numbers on the grid. Indexing is found by changing the row to the number, the column to the row and the and the number to the column. Example, if a 4 is in r7c8, then a 7 is in r8c4 AND an 8 is in r4c7. HINT: In any completely super-indexed puzzle, within each 3x3 box, the (1,2 and 3) occupy different rows and columns. The same is true for (4, 5, and 6) and also for (7, 8 and 9).
