Featured Puzzle: Gemini Sudoku #1
In Gemini Sudoku, you’re given a pair of Sudoku grids. The grid on the right works like a cipher for the grid on the left. Wherever a digit appears in the left grid, it maps to a specific digit in the same position in the right grid. For example 4 in the left grid might map to a 6 in the right grid. This means that for every 4 you discover on the left, you can place a 6 in the same position on the right.
