Sudoku Farm

Fill in the sudoku with farm animals and crops without running out of food, water, feed, manure, fuel or clothes. Play holiday and world-region farms, or design your own.

Learn sudoku one technique at a time, from finishing a row to naked and hidden pairs. Each challenge has exactly one cell to find, with hints and a full explanation.

Solve each sudoku while scoring the right number of runs each inning. Each cell is an at-bat, and the inning ends after 3 outs.

Solve each sudoku while gaining the right number of yards before you have to punt. Each cell is a play.

No digit repeats inside a zone, and the zones are gerrymandered so most of them have a larger even sum than odd sum.

Two sudokus in one grid: every cell gets a number and a color, and every number-color pair appears exactly once.

Every row is a 10-frame game of bowling. The strikes and spares are in place: fill in the digits 0–7 so each row hits its score, sudoku style, on a 16×16 grid.
