- The Level 8 guide explains a column-lock deduction without requiring the solver to choose between the two remaining brown squares.
Field notes
The instructions distinguish this game from number-based Sudoku: colored shapes define regions, and arithmetic is not part of solving. The site describes a progression from 4×4 opening boards to 9×9 puzzles, and its Level 8 example shows how shared column candidates can rule out other colors before a specific square is chosen. It also links to outside puzzle references and provides a correction route.
