This sudoku was created by my daughter Hunar Doulani. It was her first attempt at creating a 9x9 sudoku. She spent a good 4-5 hours on this. She is a big fan of Korean music. The theme of the sudoku is a Korean band Stray Kids which is abbreviated as SKZ.
RULES : Classic Sudoku rules apply. Additionally, there are some thermometer shapes in the grid. The numbers are in increasing order from the bulb to the flat end on each thermometer.
