The brief
- Normal Sudoku rules apply.
- The grid is partially covered with fog. Correct digits will clear fog around that cell.
- Cells along lines between two filled circles must have values between those in the circles.
- Adjacent digits along a green german whisper line must have a difference of at least 5.
- Adjacent cells connected with a V must sum to 5.
- Adjacent cells connected with a X must sum to 10.
- A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.
- Digits along a blue line create a sumline where the sum of digits on a line within a particular 3x3 box must be the same for all the boxes the line passes through.
- Digits along a thin grey palindrome line read the same forwards or backwards.
- Digits along a magenta renban form a set of consecutive non-repeating digits in any order.
- Digits along a yellow nabner line cannot repeat and none may be consecutive.
- Digits along red Ten Line contain contiguous groups of cells that sum to 10. These groups of cells cannot overlap. Digits may repeat freely on the line, even within sums.
- Digits along each thermometer must increase starting from the bulb end.
- The digits along each arrow must sum to the digit in the circled cell.
- Cells with a filled circle must be odd.
- Cells with a filled square must be even.
