Now I’m sharing this new and very challenging puzzle: DEKADOKU (as I’ve named it). It’s truly beautiful. The colors are decorative. The rules are as follows: 1. Place all the combinations of two-digit numbers (from 00 to 99). 2. In each row or column, no number can have the same tens digit. 3. In each row or column, no number can have the same units digit.
