I've had the idea of ​​half cells for a while, but for a long time I didn't know how to implement it in SudokuPad. I've now found a solution. Important: the cells on the diagonals remain empty and have no effect on the lines!

• Normal Sudoku rules apply twice. The grid looks like a normal 9×9 Sudoku. However, each cell is divided by a diagonal from bottom-left to top-right, forming two triangular halves. Each triangular half contains its own digit. The lower triangles together form a complete Sudoku (rows, columns, and 3×3 boxes must each contain the digits 1–9 exactly once). The upper triangles also form a separate, independent Sudoku with the same rules.
• Green lines are german whisper lines. Adjacent digits on such lines must differ by at least 5.
• Pink lines are renban lines. They contain a set of non-repeating consecutive digits.
• The blue lines are region sum lines. Box borders divide them into segements and all segments have the same sum.
• Digits on an arrow sum to the digit in the attached circle.
• Red lines are parity lines. Each pair of adjacent digits on that line must contain one odd and one even digit.
• The peach line is an entropy line. Every three consecutive cells on the line must contain one low (123), one middly (456) and one high digit (789).
• Digits on a thermometer either increase or stay the same, starting from the bulb end to the tip.
