However, and unlike Sudoku, each cell in the grid contains a letter and a number and each pair appears only once in the grid. This collection of 244 puzzles contains 3x3, 4x4, and 5x5 puzzles sorted into 'easier', 'harder', and 'numbers' categories. The hardest vaki puzzles are numbers only, where the puzzler has to work out which numbers form pairs with which numbers. The small easier puzzles are easy. The 5x5 numbers puzzles will challenge the experienced Sudoku enthusiast.
