Fractal Sudoku
Nested Sudoku, infinitely deep
$0.99 · Designed for iPad. Not verified for macOS.
Fractal Sudoku takes the classic puzzle and turns it inside out.
Every cell on the board hides another full Sudoku puzzle beneath it.
Drill down to solve them and the answers cascade back up — building the
grid above, one square at a time, three levels deep.
