Logic Masters Deutschland e.V.

This is a new game I came up with the night after my birthday. It's so simple that I couldn't sleep just thinking about it. The rules are easy: you have to place all the two-digit combinations (numbers from 00 to 99) in a grid, so that in each row and column, no two numbers have the same tens digit or the same ones digit. It’s like a double 10x10 Sudoku, but without regions, and forming a magic square (without counting the diagonals). The colors are just for decoration. Here I share an easy example, and I will share more later. Do you have any ideas for a good name for this simple but interesting game? Leave your comments!
