Five

About Five

Five is a free daily German whispers sudoku from Mind Loft. Each day gives you a 9×9 sudoku with green lines drawn across the grid, and any two squares next to each other on a line must differ by at least 5. Rows, columns, and 3×3 boxes still hold 1 through 9 exactly once, and the lines plus a handful of printed digits carry the rest.

The rule splits the digits in two: 1 to 4 are low, 6 to 9 are high, and 5 can never go on a line at all, so a line always alternates low and high. A 4 can only sit beside a 9 and a 6 only beside a 1, which is where most boards crack open. Every board has a single solution you can always reach by logic, with no guessing. Wrong entries are never flagged, so spotting your own slips is part of the puzzle, and a clean solve scores a perfect 10 with the daily leaderboard decided on the clock.

A new board drops every day at midnight Eastern; weekdays print fewer digits as the week goes on, from 20 on Monday down to 13 on Saturday, and the Sunday Edition prints just eleven under eight lines. No app, no signup, play free in your browser. Want the rest of the family? Try Cages, the killer sudoku, Sando, the sandwich sudoku, and Mercury, the thermo sudoku.
