Sudoku Pizza
I won't pretend to understand sudoku. There's too many grids, columns, rows, and numbers to deal with. The point is to fill each of nine grids with the numbers 1 through 9 such that each column and row is filled with 1 through 9 with no repeats. See, confusing, right?
But reduce it to pizza toppings, and now you're speaking my language. The Sudoku Pizza, created by Colordoku, replaces numerals with olives, basil, potato, onion, garlic, Italian salami, zucchini, sausage, and spinach. All arranged in a sudoku pattern. [via Neatorama via Gordon]
