Windoku. Hyper Sudoku.
Read full descriptionHide full description
Windoku is Hyper Sudoku — classic 9x9 Sudoku elevated by four shaded window regions that transform how you solve every puzzle. The four coloured windows are placed symmetrically inside the grid, each a 3x3 region that must also contain digits 1-9 without repetition. That gives you 13 constraint regions instead of the standard 9 — and it changes everything. Cells inside a window carry extra logical weight, the windows overlap with standard boxes and lines in ways that unlock powerful deductions, and the coloured grid is simply beautiful to look at. If you love Sudoku and want something visually fresh and logically richer, Windoku is for you.
