Donut Sudoku: The Delectable New Variant Cover

 

Synopses & Reviews

Synopsis:

How sweet it is! Solvers will gobble up this delectable new sudoku variant with a tasty twist. No numbers appear within the central box to start, leaving a "donut hole" in the middle with the numbers that are given sprinkled around the edges. That makes breaking into the central area more challenging—and provides sudoku lovers with a unique solving experience.
