Same rules, same deductions, in half the time. 1. 1 A 6×6 grid split into regions of 2 rows by 3 columns. 2. 2 Every digit from 1 to 6 appears exactly once per row. 3. 3 Exactly once per column, and exactly once per region. 4. 4 Pre-filled digits are locked: they are your footholds. ## Why play? - All the benefits of sudoko, in one coffee break. - A solid stepping stone before the 9×9 grid. - A brand new grid every day. ## Tips - Each row crosses two regions and each column crosses three. For a given digit, rule out the rows and columns that already hold it: often only one cell is left in the region. - With only six digits, a row with four filled cells has just two candidates left. Check the matching columns: one of them often already contains one of the two. - Switch on Notes mode to jot down candidates. An impossible note is refused and the cells blocking it flash, showing you the conflict at no cost. - A wrong digit still counts as a mistake after you undo it. If you are torn between two digits, note both and work elsewhere instead of taking a chance. - Long-press a digit to lock it: it is highlighted across the grid and every tap on an empty cell places it. Handy for filling in one digit everywhere in a row of taps. ## Frequently asked questions
How do you play Sudolito? Fill the 6×6 grid with the digits 1 to 6. Each digit must appear exactly once in every row, once in every column and once in every region of 2 rows by 3 columns. Pre-filled digits are locked and give you a starting point.
Is Sudolito free to play? Yes. Sudolito is free and runs in your browser, on desktop or mobile, with nothing to download. Today's grid can be played without an account. A free account unlocks the archive of past days, and SIWA+ (€18 a year) removes ads and adds advanced stats.
How is Sudolito different from a classic sudoku? The rules are the same, only the size changes: 6×6 instead of 9×9, digits 1 to 6 and rectangular 2×3 regions. A game takes roughly half as long. For the full 9×9 version, SIWA offers Sudoko.
What happens if I enter a wrong digit? The digit turns red right away and blocks the grid until you undo it. It counts as a mistake in your score, even once undone. If you get stuck, a joker reveals a cell; jokers are unlimited, but each one costs points.
Does every Sudolito grid have a single solution? Yes. Each grid is generated by an algorithm and then checked by a solver, so it always has exactly one solution. Difficulty varies from day to day, from easy to hard, and the Sunday grid is always hard. It changes at midnight, your local time.
