What is Buzz Grid?
Buzz Grid is a sudoku puzzle where each stage asks you to complete a grid so no number repeats in any row, column or box. Boards come in three sizes, 4×4, 6×6 and 9×9, and the last six stages switch to killer rules: dotted cages carry a total, and almost nothing is printed. Every stage has a single answer reachable by pure logic, checked by the game's own solver, and a wrong digit never sticks to the board.
