Touch Music Odd Talk: An Interesting Overlay

Murdoku combines Sudoku logic with murder mystery: players place suspects or victims in an N×N grid so each person appears only once per row and column, and whoever shares a region with the victim is the killer. The free web version supports Chinese, and it is based on a same-named bestselling book by Canadian puzzle designer Manuel Garand published in 2025, with 2 volumes out and a third due this October.
