About
Niclas Krasenbrink is a Sudoku author and puzzle book designer based in Germany. His work began with an old book of unusual grids, from Samurai to 16×16, and the question of why such variations are so little known. He now shares new puzzles regularly with an international Sudoku community on TikTok and turns the most popular formats into books.
A design lover at heart, he believes a Sudoku book should be as pleasant to look at as it is to solve, something you are happy to leave out on the coffee table. Paper, pen and hand lettering shape the look of his covers and layouts. His series Krasi's Sudoku combines classic grids with unexpected variations, always with clear instructions and complete solutions.
