This puzzle uses the Lots constraints invented by 99% Sneaky, including the new Parity Change Lots in Rodd Stevens and the Modular Lots invented by Heliopolix.
Normal Sudoku rules apply.
Inert Lines: All lines in the grid do not have rules of their own.
Odd Lots: A digit in a yellow circle indicates how many odd digits appear along the attached line.
Parity Change Lots: A digit in a pink circle indicates the number of parity changes [i.e. from odd to even or vice versa] between adjacent digits along the attached line.
Modular Lots: A digit in a teal circle belongs to a modular group ([147], [258], or [369]). That digit indicates how many digits from that modular group appear along the attached line.
Solution code: Row 8
